Quotation marks have 3 basic uses: 1) to enclose direct quotations that are shorter than 3 lines and use the exact words from the source. 2) to enclose unusual words that have ironic, satirical, incongruous, or sarcastic meanings. 3) to enclose titles of short works like articles, poems, songs, or chapters within books. Punctuation goes inside the quotation marks except for colons and semicolons.
