The apostrophe has three main uses: 1) to form possessives, 2) to show contractions, and 3) to form some plural forms. It is used to create possessive forms for singular and plural nouns, especially people's names. When forming possessives of plural nouns, the plural is formed first before adding the apostrophe. Contractions allow blending of sounds by omitting letters from verb constructions, with the apostrophe showing what is left out. The apostrophe is also used to form plurals of digits and letters.
