the mark , used to separate items in a list or indicate a pause in a sentence
A comma (,) is a punctuation mark used to indicate a pause or separation in a sentence. It helps clarify meaning by separating items in a list, such as "apples, oranges, and bananas," or by setting off clauses and phrases, like in "After dinner, we went for a walk." Commas are also used before conjunctions in compound sentences, as in "I wanted to go, but it started to rain." By organizing sentences and improving readability, commas play an essential role in written communication, ensuring that ideas are expressed clearly and effectively.
