The Missing Letter
Solve the crossword, find the letter no answer starts with, and save it for the week's Mystery Word.
Every day: A new crossword each day in which every answer starts with a different letter; the one letter of the alphabet left over is the day's missing letter, and the week's letters unscramble into a Mystery Word.

The Missing Letter is a daily crossword from Merriam-Webster, written by Matt Gaffney using the Collegiate Dictionary. Many clues are dictionary definitions, and each answer begins with a different letter. The letter of the alphabet that no answer starts with is the day's missing letter, and at the end of the week you unscramble the missing letters into a Mystery Word.
