Use apostrophes, capital letters, colons, commas, exclamation points, hyphens, periods, question marks, and quotation marks correctly in writing. Each punctuation mark has specific rules for its use, such as using apostrophes to form contractions and possessives, capitalizing proper nouns and the first word of sentences, and placing commas between independent clauses joined by coordinating conjunctions. Punctuation helps clarify meaning and ensure readers comprehend the writer's intended message.
