comma
The comma ( , ) is one of the most commonly used punctuation marks in English. Commas are the same in appearance as apostrophes ( ’ ), but are placed on the bottom line of the text, in the same location as periods.
Generally speaking, commas are used to connect two or more elements in a sentence, but the way in which they do this varies widely, depending on what these elements are and how they are arranged in the sentence.
