Do You Need a Comma Before Again at End of Sentence

May 08, 2022 Post a Comment

In the early on 1990s, at school in Oxford, England, my English language teacher tried to teach u.s. how to use commas. I remember it so well because of the feeling of utter artifice that overcame me. In an try to simplify the circuitous rules of comma punctuation placement, my teacher used the rough-and-set up rule of "you should employ a comma where you would break in speaking". In retrospect, I think this merely confused me more than. I'chiliad sure many people take felt the aforementioned style.

Commas are one of the most frustrating grammatical concepts, even for native English speakers. Notwithstanding, there are specific rules for when y'all should and shouldn't use commas. Building our grammar checker we've identified 26 places where y'all might need a comma. In this article, I will explain all of these places along with examples of how to use commas in English language sentences. Just bookmark this article in case you ever get confused by a comma over again.

You'll come across lots of articles named things like "13 Rules for Using Commas" or "8 Unproblematic Comma Rules". The reality is that there are many more rules for using commas. Don't despair though. Different many rules in English language, they really brand sense, as they are designed to assistance avert defoliation. Missing commas tin take a HUGE impact on the meaning of your sentence. Missing commas can fifty-fifty cost a million dollars.

To produce this list, our team of linguists analyzed thousands of sentences and classified every comma in each judgement according to its use. They also found MANY mistakes besides. We used all of this data to build our listing and to railroad train the automated comma checker in our free grammer checker. All the data below is congenital into our grammer checker so that every time you brand a mistake you can come across why.

So, where exercise commas go in a sentence? This is the definitive list:

Earlier a coordinating conjunction when it separates 2 contained clauses.
Before "so" when information technology separates two contained clauses.
Earlier a coordinating conjunction when it separates an independent and dependent clause equally an Oxford comma.
Afterwards an initial/introductory adverb that modifies a whole sentence or independent clause.
After a time phrase that comes before a sentence or independent clause.
Later on a subordinate clause—1 that starts with a subordinating conjunction.
Earlier a subordinate clause—in some specific cases.
Between two adjectives when they both change the noun—coordinate adjectives.
After an introductory prepositional phrase.
Earlier and after a participle phrase.
When a word is omitted intentionally for stylistic reasons.
After an adverbial infinitive phrase.
At the finish of a quotation, earlier the endmost quotation marking.
Earlier an opening quotation marker.
To prepare off contrasting phrases.
Earlier an appositive.
Afterward an appositive.
Before "which" in nonrestrictive phrases.
To carve up list items.
To divide out a parenthetical element of a sentence.
To separate urban center and country/city and state.
To prepare off a vocative.
To divide the day from the calendar month, and the appointment from the yr.
Earlier and after "too."
In numbers as a separator.
Before and after "please."

That'southward a long list, and it requires some knowledge of grammatical terminology to procedure it. So let's look at specific questions and examples of comma usage.

Is information technology grammatically correct to put a comma earlier "and"?

It is grammatically right to apply a comma before "and" (and other coordinating conjunctions such as "just", "or", "nor") merely when it splits two contained clauses (i.e. if you remove the "and" you volition be left with two consummate sentences), or if yous're using information technology equally an Oxford comma.

There are three ways that "and" can be used in a judgement: - To separate two independent clauses, i.east. you lot should be able to remove the "and" and be left with two complete sentences. - To separate two dependent clauses, i.east. if you took the "and" away then you wouldn't have two sentences. - To carve up items in a listing, e.g. buckets and spades, or lions and tigers and bears. A comma is used before an "and" only if it is used to dissever ii independent clauses, or if information technology is used equally an Oxford comma to dissever the final item in a listing of iii or more things.

Right: He is great, and I admire him.

In this example in that location are two independent clauses as I could write: "He is great." and "I admire him."

If both the independent clauses are short then some writers may choose to omit the comma before the "and", but you volition never be incorrect to use it. So if yous're not sure so I advise you to include it.

If I wrote instead: "He is cracking and works hard," this is an independent clause and a dependent clause, considering "works hard" is not a complete sentence.

Correct: He is great and works hard. Incorrect: He is peachy, and works hard.

In some circumstances, y'all may use a comma before a conjunction such as "and" when it starts a dependent clause. This is when you are using the comma as an Oxford comma (sometimes known equally a serial comma). The conjunction must split the third item of a listing. eastward.g. I ate, slept, and dreamed of England.

Is it grammatically right to put a comma before "and so"?

The word "then" tin part as several parts of speech. For comma usage, the most of import usage is as a conjunction. In theory, "then" is not a analogous conjunction (similar "and", "or"), merely sometimes information technology is used every bit such.

Example: I went to bed, then I started dreaming.

Hither, "then" is used as a shortened grade of "and and so". Some people might strongly disagree with this sort of sentence, but the truth is that it is widely used, even past The New York Times.

Yous tin read more in this article.

We recommend that where "then" tin can exist replaced by "and and so" you use the same rules for comma placement as adding a comma before an "and", i.due east. add together i if the following phrase is an contained clause.

Should I use a comma afterwards an introductory adverb like "obviously"?

Adverbs are words that alter verbs or even whole sentences. They oftentimes end in "-ly". Examples include "chop-chop", "oft", "slowly". Y'all can see that they "add" some information to a "verb" or the sentence that they are modifying. Some adverbs don't terminate "-ly", eastward.g. "sometimes" or "often".

When an adverb modifies an unabridged sentence or contained clause that follows it then you should employ a comma after it.

Correct: Sadly, they didn't understand me.

Incorrect: Sadly they didn't empathize me.

Right: Strangely, the volume hasn't arrived.

Incorrect: Strangely the book hasn't arrived.

And so when "apparently" modifies the whole sentence or clause that follows it then it should be followed by a comma.

Right: Plain, he doesn't have a clue.

Incorrect: Evidently he doesn't accept a clue.

Should I use a comma after a fourth dimension phrase such equally "in the meantime"?

A fourth dimension phrase is something that gives details of the time that something happened. It might be a single discussion or a complete phrase. Some examples of fourth dimension phrases are tomorrow, at 2pm, five hundred years ago, and in the concurrently.

When a time phrase adds information to an independent clause or sentence that follows it and so it should exist followed by a comma. If the phrase or sentence comes earlier the time phrase and then it shouldn't take a comma before it.

Correct: Five hundred years ago, in that location were no grammar books.

Wrong: 5 hundred years agone there were no grammar books.

Correct: There were no grammar books five hundred years ago.

Incorrect: At that place were no grammar books, five hundred years ago.

Correct: Yesterday, there was no new news.

Incorrect: Yesterday there was no new news.

Right: There was no new news yesterday.

Wrong: There was no new news, yesterday.

How should I use a comma with a subordinate clause?

Subordinate clauses are sentence fragments that start with a subordinating conjunction (e.grand. after, although, as, as if, as long every bit). They tin can't course a sentence on their ain, only they add data to the main clause, usually some form of condition, eastward.m. if y'all do this, whenever you encounter him.

Subordinate clauses are great because they add variety to your writing, but ofttimes, writers are not sure how to use commas with them. A missed comma afterwards a subordinate clause is one of the about common mistakes that we see. So how do you punctuate a subordinate clause? It turns out there is a pretty simple dominion:

If a subordinate clause comes earlier the clause it is attached to then information technology should exist followed past a comma. You do not need a comma before a subordinate clause if information technology follows the main clause (except "whereas" and "although").

Correct: If you're gear up, we can brainstorm.

Correct: We can begin if you're ready.

Incorrect: If y'all're ready we can brainstorm.

Wrong: We can begin, if you're ready.

Correct: Although y'all're ready, we must wait.

Correct: We must wait although you lot're fix.

Wrong: Although you're set up we must expect.

Incorrect: We must look, although yous're ready.

Should you employ a comma before "whereas" and "although"?

The words "whereas" and "although" are subordinating conjunctions. The general rule for subordinating conjunctions states that you shouldn't use a comma before a subordinating conjunction that comes after the master clause. However, "whereas" and "although" are examples of "adverbs of concession," along with "though" and "even though". They are used where a dependent clause is contrasting to the main clause (a bit like "but"). You should utilise a comma to introduce a dependent clause that starts with an adverb of concession.

Correct: I waited at the door, whereas Katy waited in the street.

Wrong: I waited at the door whereas Katy waited in the street.

Should you employ a comma before "while"?

Slightly more complex is the question of whether you should use a comma before "while." While is a subordinating conjunction, only in some circumstances it tin can act as an adverb of concession likewise. In these circumstances it should have a comma earlier it.

If yous can supervene upon while with as, and so it shouldn't have a comma before it. It is just a normal subordinating conjunction. If you lot can replace while with whereas so you lot should employ a comma before it considering it is existence used equally an adverb of concession.

Correct: The man left the eating place while [as] information technology was raining.

Incorrect: The man left the restaurant, while [as] it was raining.

Correct: The human left the eatery, while [whereas] his partner stayed.

Wrong: The homo left the eatery while [whereas] his partner stayed.

Should yous have a comma earlier "because"?

In most circumstances, "because" is a subordinating conjunction, and then when it starts a dependent clause after the main clause, it shoudn't be preceded past a comma. All the same, there are two exceptions to this rule:

when the contained clause that comes before "because" contains a negative verb (e.g. don't, couldn't, wouldn't)
when the independent clause that comes before "because" contains 2 elements and it is unclear which i "because" refers to.

Let's expect at an example of when the independent clause that comes before "considering" contains a negative verb:

He didn't take the exit because of the fog.

This example is disruptive because yous're unsure whether it was the fog that caused him to miss the exit, or some unknown factor. e.g. He didn't accept the exit because of the fog, but considering he wasn't paying attention.

Where you hateful that the fog didn't crusade him to miss the go out it might exist best to rewrite it as: The fog didn't cause him to miss the exit. If you lot mean that he missed the exit considering of the fog, and then you should include a comma.

Correct: He didn't take the get out, considering of the fog.

Incorrect: He didn't take the go out considering of the fog. (ambiguous)

Correct: I couldn't come, because of the traffic.

Incorrect: I couldn't come because of the traffic. (cryptic)

Correct: I couldn't come considering of the traffic, only because my car broke downwards.

Correct: It wasn't the traffic that meant I couldn't come, information technology was because my auto broke down.

Let'due south await at an example of when there are 2 elements in the contained clause that precede "because" and the dependent clause could refer to either ane.

I thought you lot sent me flowers because I saw you yesterday.

Did you send me flowers considering you saw me yesterday, or did I think y'all sent me flowers considering I saw you yesterday and you hinted y'all might?

As a side note, these kinds of ambiguous constructions are best avoided. Rewrite them to exist unambiguous. Any sentence that cause ambiguity in your readers' minds stops them understanding your message.

Should I use a comma earlier "for"?

In some circumstances, "for" can be replaced with "because". In that case then information technology follows the rules for "because" outlined above, i.eastward. only include a comma before "for" when the verb in the independent clause that precedes it is negated and this might cause confusion.

Should I utilize a comma before "since"?

In some circumstances, "since" can be replaced with "because". In that instance and so it follows the rules for "because" outlined above, i.east. only include a comma before "since" when the verb in the independent clause that precedes it is negated and this might cause defoliation.

Should I utilize a comma between two adjectives?

Adjectives are words that modify a noun like "one-time", "ruddy", "greasy". They should really exist called "adnouns" to be consistent with "adverbs." Sadly, they're not, only that's a good way to think of them.

You should use a comma between 2 adjectives when they are coordinate adjectives. Coordinate adjectives are two or more than adjectives that depict the same substantive equally.

With coordinate adjectives yous can put "and" betwixt them and the pregnant is the same. Similarly, you can swap their order.

For example: The long, metal pole. "Long" and "metal" are both adjectives that describe the noun "pole": I could write "long pole" or "metal pole". I could likewise write "long and metal pole" and "metallic and long pole" and "metallic, long pole". They might sound slightly foreign merely the meaning is retained.

Cumulative adjectives build on each other and cannot be re-ordered or split with "and," for example: vivid xanthous jacket. It can't be "bright and xanthous jacket" or "xanthous bright jacket".

Because coordinate adjectives are equally important, they are separated by a comma. Cumulative adjectives aren't as important and and then they are not separated by a comma. Only use a comma to separate ii adjectives if you lot could also write "and" in that location and keep the same meaning.

Correct: The long, metal pole stuck out of the ground.

Incorrect: The long metal pole stuck out of the ground.

Correct: The vivid yellow jacket looked amazing.

Incorrect: The vivid, yellow jacket looked astonishing.

Do you always put a comma after a prepositional phrase?

An introductory prepositional phrase sets the scene for the main phrase. It is oft to practise with time or location, e.g. In the forenoon or In 2018. An introductory prepositional phrase starts with a preposition (words like in, on, after, earlier).

For curt introductory phrases (fewer than 4 words), you can choose to add a comma or not. For longer phrases, you should always use a comma.

Short prepositional phrase:

Correct: In the morning let'south become to the zoo.

Right: In the morning, let's go to the zoo.

Longer phrase:

Correct: On the forenoon of his birthday, Robbie wanted to go to the zoo.

Wrong: On the morning of his birthday Robbie wanted to go to the zoo.

Note: yous might also find these prepositional phrases in the middle of sentences later on a conjunction, e.g. He went to bed, and in the forenoon, he wanted to go to the zoo. For these, you lot should follow the same rules as if they came at the offset of a judgement.

Should I use a comma with a participle or gerund phrase?

Participle phrases are phrases that modify a noun or pronoun. They add together extra context. Hither are a couple of examples:

Example: Walking to the shops, he saw his cousin.

Example: Upset by his cousin, he went domicile.

Example: Frank, hoping to get promoted, applied for the role.

Instance: Anne applied for the role, hoping to get promoted.

Example: Katy walked home, tired from a hard twenty-four hour period in the part.

The two forms of participle phrase y'all can see here are:

Nowadays participle (always catastrophe -ing), e.g. walking, hoping.
Past participles (often ending -ed, but sometimes irregular), eastward.g. tired, upset.

Note: sometimes participle phrases can be disguised if in that location is an adverb on the forepart, e.g. Desperately seeking shelter, he ran into the edifice.

The comma rules yous need to know for participle phrases are:

For participial phrases earlier the main clause, put a comma after the participial phrase.
For participial phrases in the center of the sentence, the phrase requires commas both before and after it.
For participial phrases later on the main clause, put a comma before the participial phrase.

Practice I need a comma when I omit a discussion for stylistic reasons?

Sometimes when writing we omit words for stylistic reasons. This comma of omission is oftentimes seen when parallel structures are used, such as two sentences taking the same grade.

Example: I loved playing tennis; my blood brother [loved] volleyball.

Right: I loved playing tennis; my brother, volleyball.

Incorrect: I loved playing tennis; my blood brother volleyball.

We also need to include a comma of omission when we have removed a analogous conjunction (usually "and"). This construction is fairly rare.

Example: I opened the boot [and] saw the spare tyre.

Correct: I opened the kick, saw the spare tyre. Incorrect: I opened the boot saw the spare tyre.

Correct: Carrie mimicked his tilted caput, [and] then laughed.

Incorrect: Carrie mimicked his tilted head [and] so laughed.

Do y'all demand a comma later on an adverbial infinitive phrase?

Infinitive phrases begin with an infinitive (to + the simple form of the verb), e.thousand. to exist ameliorate, to win at lawn tennis, to save money.

Infinitive phrases tin can function in a judgement every bit nouns, adjectives or adverbs. From a comma perspective you only demand to worry about ones that function as adverbs. These are oft found at the start of a sentence, but are not the subject.

Instance: To be the best, you lot must practice.

Instance: To read more, please subscribe to our newsletter.

When an adverbial infinitive phrase introduces a main clause and so you should always follow information technology by a comma:

Correct: To be the best, yous must practise. Incorrect: To exist the best you must practise.

But be careful that the phrase is not interim as a noun. Never put a comma after an adverbial phrase when "is" or "was" directly follows:

Right: To be the all-time is his goal.

Wrong: To exist the best, is his goal.

When an adverbial infinitive phrase is found in the middle of a sentence you should surround it with commas. In this case, it is acting as an interrupter:

Correct: The adjust, to be fair, suited him.

Incorrect: The adapt to be fair suited him.

Incorrect: The suit, to exist fair suited him.

Wrong: The conform to be off-white, suited him.

When an adverbial infinitive phrase finishes a main clause then you shouldn't utilise a comma before it:

Right: The suit suited him to be fair.

Incorrect: The conform suited him, to exist fair.

Should I use a comma at the end of a quotation, earlier the closing quotation mark?

In American English language, you should always place a comma or catamenia inside quotation marks. In UK usage, y'all can cull. Most style guides, such every bit the Modern Language Association (MLA), Associated Press (AP), and The Chicago Manual of Style (Chicago) advise the American rule. If you lot're uncertain who your audience will be so it's best to always place your commas within of quotes. That way you'll never been seen as wrong.

Correct: "I'll come along later," said Mary.

Incorrect in U.s.: "I'll come forth afterwards", said Mary.

Incorrect in The states: "I'll come up forth later" said Mary.

Should I use a comma before an opening quotation marker?

When you include quoted cloth or dialogue in a sentence and so yous should proceed information technology with a comma unless it fits into the menses of the judgement seamlessly, e.one thousand. The President said that there is "no smoking gun" to exist institute.

In these cases, the sentence would exist syntactically right without the quotation marks, and you are only using the quotation marks to evidence that the quote is a direct quote. Often, in this scenario, the quote will exist preceded by "that", e.thousand. He said that "the country will proceed to grow."

Otherwise, yous should utilize a comma before opening quotation marks, e.yard. Sandra called out, "What do y'all want from the store?"

Should I utilize a comma before "which"?

To sympathize if yous should use a comma before which we need to understand the difference between a restrictive and a non-restrictive clause.

A restrictive clause is one where its removal would change the meaning of the sentence. It is necessary for understanding the meaning of the judgement. In the US, many style guides suggest that you should use "that" rather than "which" for restrictive clauses, eastward.1000. The fruit that we bought was tasty.

A non-restrictive clause does not alter the meaning of the judgement. This additional data is used with "which" and a pair of commas placed before and after the clause:

Correct: The fruit, which anybody institute tasty, was my best thought.

Wrong: The fruit which everyone found tasty was my best thought.

Wrong: The fruit, which anybody found tasty was my best idea.

Wrong: The fruit which everyone plant tasty, was my best idea.

"Which" tin can also appear as role of a prepositional phrase, east.thou. The team in which we played was bully. When "which" appears in a prepositional phrase, information technology should not be preceded by a comma. Other examples of which in a prepositional phrase are "on which" and "of which."

Correct: The games, the longest of which lasted two hours, were fun.

Wrong: The games, the longest of, which lasted two hours, were fun.

Correct: The situation in which we found ourselves was fun.

Incorrect: The state of affairs in, which nosotros institute ourselves was fun.

Should you employ a comma before "which" in an indirect question?

When you're using "which" at the start of an indirect question, it should be preceded by a comma.

Correct: I asked, which is the best?

Incorrect: I asked which is the all-time?

This is like to the rule about using a comma earlier a quotation as you tin imagine the indirect question being surrounded past quotation marks.

Should I use a comma before and subsequently an appositive?

An appositive is a give-and-take or phrase that helps to further identify a noun. Ofttimes the appositive tin can be swapped with the noun it helps describe.

Example 1: Manuel Picon, the former French President, visited the U.k. yesterday.

Example 2: The former French President Manuel Picon visited the United kingdom of great britain and northern ireland yesterday.

Notice that in the first example, we utilise commas effectually the appositive, but in the second example we don't. That's the trick hither. If the appositive is essential to the meaning of the phrase then we don't accept commas, i.eastward. in Example 2 if nosotros remove "Manuel Picon" we don't know which sometime French President we're talking about. In Example 1, nosotros know exactly who visited the UK, so nosotros add commas around the appositive considering it is non-essential.

In some cases it can be tricky to decide. For instance, if I say: My sister, Mary, will come then I may or may not use commas depending on the context. If I take several sisters and it is unclear which one will come without the appositive then I should non utilize commas. If I have simply i sister so I should use commas. Only consider whether the significant is unclear if the appositive is removed and if information technology is so don't use commas.

Should I apply a comma earlier "not"?

Commas are oft used to set off a contrasting element in a sentence. These contrasting elements oft first with "not": eastward.one thousand. He chose the greenish, not the red., It happened at night, non during the mean solar day.

When not starts a contrasting phrase and then you should continue it with a comma.

Not can also be used as a uncomplicated describing word. In this example, you wouldn't use a comma earlier not: due east.g. He is not happy., She is non going to come.

Should I use a comma earlier "all the same"?

Notwithstanding can be used to get-go a contrasting element in a sentence, eastward.g. She was lamentable, nonetheless relieved.

When yet is used to set up off a contrasting element of a sentence then it should have a comma before it, simply like with not.

Other examples of contrastive elements that should be preceded with a comma are:

You lot're coming, aren't you?

The statue seemed different, well-nigh alive.

The politician seemed stupid, peradventure even moronic.

This last case shows that sometimes contrasting elements can exist disguised with an adverb before them. So sometimes you might have to expect at the second word of a contrasting element to determine whether or non information technology needs to be proceeded with a comma.

Practice I demand to use a comma with list items?

When we have a list of 3 or more items, we use a comma to split the items in the listing. This comma is known as a listing comma, e.k. I like rice, beans, and plantains. Listing commas tin unremarkably be replaced past "and" or "or," eastward.one thousand. I like rice and beans and plantains.

Listing commas can separate lists of nouns, verbs, adjectives, dependent clauses, or even complete sentences. This can mean that y'all tin have a comma before an "and" that is followed past a dependent clause if it is the terminal item in a listing of dependent clauses. Some authors similar to join sentences with list commas, due east.g. I came in, I saw the package, and I opened it.

When using listing commas, the comma before the final "and" or "or" is optional depending on if you are using Oxford commas or not. How to use an Oxford (or series) comma.

How do I use commas with parenthetical elements?

A parenthetical chemical element is an element of a sentence that is added but is not essential to the meaning of the sentence. It adds color to the sentence, e.g. Of all the chilli sauces I've tried, and I've tried a lot, this is my favourite. or Some people, who I won't name, wouldn't similar this.

Unremarkably a parenthetical chemical element has a comma before and subsequently information technology. Instead, you lot might choose to use brackets or dashes to divide a parenthetical element from the balance of the sentence.

Here are some examples of parenthetical items used correctly with commas:

Maria, although she comes from Spain, hates paella.
This is, in my stance, the virtually important upshot.
The biggest issue, every bit you will see, is where we will store all the extra components.
The holidays in Spain, of which there are many, are generally religious.

Interjections such as "yes" and "no" are generally treated as parenthetical elements. When they come at the start of a judgement, they should be followed by a comma. When they come at the stop of a sentence, they should be preceded past a comma.

Should I utilize a comma between a city and a country/a city and a state?

In geographical names with ii or more than elements, you should apply a comma after each different element. This helps the reader to see the dissimilar component parts of the accost. You should likewise use a comma after the last item in the name unless it comes at the cease of the judgement in which case you should use a period (or question mark if it is a question). e.g. Is Oxford, England, full of clever people?

The main times when geographical names are equanimous of 2 or more entities are:

between a hamlet/boondocks/city and a country, e.chiliad. I live in Miami, Florida.
betwixt a village/town/city and a country, due east.g. I live in Liverpool, England.
between a county and a land, e.yard. I alive in Cook County, Illinois.
between a county and a country, e.g. I live in Cornwall, England.
between a village/town/city and a region, e.g. I live in Garsington, Oxfordshire.
betwixt a region and a state, e.k. I live in Tabasco, Mexico.

A classic instance would be if you lot used an address in a piece of text, e.k. Eric Wimp, living at 29 Acacia Route, Nuttytown, eats a banana to transform into Bananaman.

The parts of an address should be separated by commas and information technology should be followed by a comma unless it appears at the cease of a judgement.

Should I use a comma before and subsequently vocative?

A vocative is when you apply accost someone by name, e.g. Pass the table salt, Mary. or Are you a prince, Harry? or 1000000, are you there?

Vocatives are usually found at the beginning or the end of a sentence, only they can be included in the middle of a sentence, e.g. What, Harry, is your title?

Vocatives should e'er exist used with commas. Hither are the three rules for using commas with vocatives:

utilize a comma afterwards a vocative at the start of the judgement.
utilize a comma before a vocative at the stop of the sentence.
utilise a comma earlier and afterwards a vocative in the middle of the judgement.

Correct: What is that, Frank?

Incorrect: What is that Frank?

Correct: Frank, what is that?

Incorrect: Frank what is that?

Correct: What, Frank, is that?

Incorrect: What Frank is that?

Incorrect: What, Frank is that?

Wrong: What Frank, is that?

In some cases yous might not use someone'due south proper name to refer to them, but a championship, or other description. Some examples of this are: sir, madam, boy, darling, sweetheart, pal, gentlemen, folks. eastward.one thousand. It's great to see you here today, folks.

When using a vocative in the middle of a sentence, make sure that you're not actually creating a comma splice by joining two contained clauses.

Right: This is great, Joe. I love it.

Incorrect: This is great, Joe, I love information technology.

Correct: We love it, Louise. Nosotros'll use it.

Incorrect: We love it, Louise, we'll employ it.

Do you demand a comma to separate the mean solar day from the calendar month, and the date from the year?

When you write a appointment, you should use a comma to carve up the day from the month, and the appointment from the year, e.g. He was born on Oct 8, 1977. or Today is Tuesday, August viii, 2019.

Correct: I was born on Sat, October 8, 1977.

Incorrect: I was born on Saturday October eight, 1977.

Wrong: I was born on Saturday October viii 1977.

Incorrect: I was built-in on Saturday, October 8 1977.

If you put the twenty-four hour period of the month start, e.g. 12 May 2012, then at that place is no need to include commas in the date.

Do yous need a comma before or after "also"?

Too is an adverb. It's usually used to hateful "in addition" or "also." I would say that "as well" is one of the hardest words to know whether you lot should use a comma or non. It really depends and many editors will have contradictory views. On the other hand, yous could say that's corking news as you'll never be wrong. If you want to emphasize the "too" and then employ a comma, just if it'southward not that of import then you tin become abroad with leaving them out.

If "likewise" comes in the middle of a judgement then yous should either have two commas or no commas. If you simply accept a single comma before or after then that's definitely wrong.

Correct: I, too, like being with you. (accent)

Right: I too similar being with you lot. (no emphasis)

Incorrect: I too, similar being with you.

Incorrect: I, too similar being with y'all.

Right: I like y'all, too. (emphasis)

Correct: I like y'all too. (no emphasis)

When should I utilize a comma to separate numbers?

In English, we employ commas in numbers greater than 999 to dissever the number and make it clearer. Nosotros apply a comma every 3rd digit from the correct.

Incorrect: More 50000 people turned up to protest. Correct: More 50,000 people turned up to protest.

Note how much easier it is to read. The comma every 3rd digit is sometimes known as a "thousands-separator." Make sure you don't include a infinite on either side of this comma.

Correct: We will walk 10,000 miles.

Incorrect: We will walk 10, 000 miles.
