Commas

A comma is a punctuation mark used to separate words, ideas, and phrases. A punctuation mark is a symbol or sign used to direct the reader’s understanding of a sentence. For example, we use periods to mark the end of a sentence, exclamation points to show excitement, and question marks to show that the sentence should be read as a question.
