The clues for the words are usually provided in the form of a list of words or phrases, and the answers are usually related to a particular THEME. The goal of the puzzle is to fill in all the squares correctly. CLUE is a four-letter word that refers to the hints given to help solve the puzzle, while THEME is a five-letter word that refers to the overall topic or idea that the puzzle is based on.
