A crossword puzzle clue phrased as a question challenging authority or source, often seeking a specific name or title, serves as a prompt for solvers to recall a particular figure associated with a famous quote, saying, or idea. For example, the clue “___ cogito, ergo sum” expects the solver to fill in “Descartes.” This type of clue tests knowledge of both the quotation and its originator.
Such clues provide a stimulating intellectual exercise, encouraging solvers to delve into history, literature, philosophy, and popular culture. They add a layer of complexity beyond simple vocabulary recall, demanding an understanding of context and attribution. Historically, crossword puzzles have utilized this question format to test deeper knowledge and engage solvers with a wider range of intellectual disciplines. This approach contributes to the enduring popularity of crosswords as both a pastime and an educational tool.
