*Apostrophes indicate possession – something belonging to something or someone else.
*To indicate something belonging to one person, the apostrophe goes before the ‘s’. For instance, “The girl’s horse.”
*To indicate something belonging to more than one person, put the apostrophe after the ‘s’. For example, “The girls’ horse.”
*Apostrophes are also used to indicate a contracted word. For example, “don’t” uses an apostrophe to indicate that the word is missing the “o” from “do not”.
*Apostrophes are never used to make a word plural, even when a word is in number form, as in a date.
