Riddle: Which word is the odd one out: BAIL, FAIL, PAIL, RAIL, SAIL, TAIL?
Answer: FAIL is the odd one out because it does not have a homophone. BAIL has BALE (like a bale of hay), PAIL has PALE, SAIL has SALE, TAIL has TALE, and RAIL has RALE. FAIL has FALE, which is not a real word, and therefore cannot be a homophone.
