Where's your apostrophe?
Apostrophes are those tricky little upside-down commas that we all know and love. Although we all learned about apostrophes in elementary school (sometimes appropriately called "grammar school"), many people seem to misuse apostrophes with startling regularity.
I have personally been horrified to see apostrophes increasingly misused to form plurals on signs. (For example, "banana's for sale.") With this quiz, you can prove to all that your punctuation skill level is comparable to the average fourth-grader! Give it a try.
