The comma( , ) is a punctuation mark, and it appears in several variants in various languages. It has the same shape as an apostrophe or single closing quotation mark in many typefaces, but it differs from them in being placed on the baseline of the text.
In English writing, quotation marks or inverted commas(" ") (informally referred to as quotes or speech marks) are punctuation marks surrounding a quotation, direct speech, or a literal title or name.
