A “have-not” crossword clue is a type of cryptic crossword clue that uses wordplay to indicate that something is missing. The missing element is usually a letter or a word, and the solver must determine what it is in order to complete the puzzle.
Have-not clues are often used to add an extra level of challenge to a crossword puzzle. They can also be used to create humorous or puzzles. For example, a have-not clue might be “What do you get when you take the ‘t’ out of ‘potato’?”, with the answer being “a potato”.
