International Apostrophe Day
August 15 · Level 2 · #1875 of 2238

The apostrophe is a tiny mark with a big talent for starting arguments. This day is a friendly nudge to use it properly, whether it shows a missing letter or ownership.
How it is celebrated: grammar fans hunt for stray apostrophes on shop signs and menus, swap favourite examples of famous blunders, and quiz their friends and colleagues on when the mark belongs.
The word comes from the Greek apostrophos, meaning "turning away", as if the mark were turning its back on the letter that has gone missing.
