Punctuation is the use of marks or symbols in writing and printing to clarify meaning and guide the reader's understanding. It helps to organize and structure sentences, indicate pauses or stops, emphasize certain words or phrases, and convey the intended tone or expression. Common punctuation marks include commas, periods, question marks, exclamation points, colons, semicolons, quotation marks, apostrophes, hyphens, parentheses, brackets, and ellipses.
