Definition: A comma separates elements in a sentence, such as items in a list or series, but it also shows that those elements are connected to each other within the same sentence. A comma is never used as an end mark, and it is read with a shorter pause than an end mark. One use of the comma is to separate three or more words, phrases, or clauses in a list or series. Commas go after each item except the last.
In British usage, there is no comma before the conjunction (such as and or or) before the last item in the series.
Each of the following sentences contains a series. If necessary, insert a comma (or commas) by clicking the space(s) after the appropriate word(s). If the sentence is punctuated correctly, click "correct as is" at the end of the sentence.
