What is the purpose of a comma in writing?

The comma functions as a tool to indicate to readers a certain separation of words, phrases, or ideas in order to prevent misreading the writer’s intended meaning. When a sentence is spoken aloud, a comma often represents a pause, which in verbal conversation functions to clarify meaning.

Why do people put commas at the end of sentences?

What are the five primary uses of a comma?

Separating the main elements of a sentence from each other. Setting off a parenthetical element from the rest of the sentence. Separating elements in a series. Setting off dialogs or quotations.

Can you replace a period with a comma?

A comma after a period is necessary when the period ends an abbreviation in a list, introductory expression, parenthesis, salutation, compound sentence, and inverted complex sentence. But, no comma is needed when the abbreviation is used as a name title or prefix, essential sentence element, and suffix.

Does a comma go before or after but?

You should put a comma before but only when but is connecting two independent clauses. I would go for a walk, but it’s raining outside.

Can a sentence end with a coma?

How do you end a quote without a period?
