A cruciverbalist is a person who is skilled at creating or solving crossword puzzles. The term is a combination of "cruci-" from "crucifix," meaning cross, and "verbalist" from "verbal," indicating a person who deals with words. cruciverbalists are often responsible for designing crossword puzzles, and they possess a deep knowledge of wordplay, vocabulary, and the techniques used in constructing and solving crosswords. They aim to make puzzles that are both challenging and enjoyable for crossword enthusiasts.
