For example, a clue might be “Repel, as pests” with a solution like “DETER.” This action of causing something to leave is central to understanding how the clue functions within the puzzle’s framework.
Such clues, focusing on actions of expulsion or dissuasion, serve several crucial functions. They broaden the range of vocabulary employed, enriching the solver’s experience. They also introduce an element of complexity, requiring solvers to think beyond simple synonyms and consider a wider range of semantic relationships. This complexity contributes to the enduring popularity and mental stimulation provided by crossword puzzles. Historically, this type of clue has been a staple, reflecting a consistent need to test vocabulary beyond mere recall.
