I think you are thinking of a series comma. It is used when there are three or more things listed. Example: I bought the butter, milk, and eggs. The second comma is the series comma. I was taught that it is the preferred method, but many publishers do not use it, particuarly newspapers. No. In lists you can omit the last comma: the idea is that the comma takes the place of and anyhow. This method is more common in England. In America the use of the extra comma (called the Oxford comma) is more common. Like the above answerers have already explained, you don't necessarily need the last comma in a series of words/phrases. Whether you use it or not depends on where you learned English, who you learned it from, and personal preference. I think the extra comma helps the reader to understand what they are reading, but it really doesn't matter. <br /><br /> However, you may also be talking about using <i>and</i> in a compound sentence. For example, you would say, "George ran a mile, and he also practiced rim shots." Note the comma between the two complete phrases. You only put it there if the second phrase is insubordinate, or stand-alone (it needs a subject and a predicate). Without the comma, you would have to remove the subject like so: "George ran a mile and also practiced rim shots." <br /><br /> As a review, you DO use a comma if you have two or more STAND-ALONE (subject and predicate) clauses.
No, you do not need to put a comma after "To begin with" when it is used as an introductory phrase in a sentence.
Exclamations are typically separated from the rest of a sentence by a comma. "Oh! I didn't know that!" "Oh, it isn't that important."
Not usually : "Thank you for listening to me" does not need a comma. However, if you write their name afterward ("Thanks, Fred."), you need a comma after thank you.
A comma is typically used before "but" when it connects two independent clauses. However, if "but" is joining phrases within a single sentence, a comma is not necessary.
You generally need to put a comma before a subordinate clause when it follows an independent clause. This comma helps indicate the separation between the two clauses and improves clarity in the sentence structure.
you do not have to put the comma there
it needs a comma
"In five years, things happened." Yes you do need a comma.
No. There is no word in English that always requires a comma before it.
Not necessarily. The comma indicates a pause in speech. Use a comma after "but" only to indicate a noticeable pause in speech. If there is no pause, there should be no comma.
No
No, you do not need to put a comma after "To begin with" when it is used as an introductory phrase in a sentence.
Exclamations are typically separated from the rest of a sentence by a comma. "Oh! I didn't know that!" "Oh, it isn't that important."
Only proper nouns and I are capitalized after a comma. But is a conjunction, so no, it doesn't need to be capitalized.
You only need one space after a comma.
Not usually : "Thank you for listening to me" does not need a comma. However, if you write their name afterward ("Thanks, Fred."), you need a comma after thank you.
When you combine two independent clauses, you need to separate them with a semicolon--not a comma. If you use a comma instead of a semicolon, the result is called a comma splice.
