Error #9




Check all of your nouns ending in -s to see if any of them are possessives. To make a noun possessive, you must add either an apostrophe and an -s (Ed's book) or an apostrophe alone (the boys' gym). Possessive personal pronouns, however, do not take apostrophes: hers, his, its, ours, yours.
