This phrase describes a specific type of crossword clue where the answer is a word or phrase signifying an inability to articulate thoughts or feelings, such as “speechless,” “dumbfounded,” or “tongue-tied.” A clue might be phrased as “Unable to speak (3,1,4,5)” with the answer being “AT A LOSS FOR WORDS.” This type of clue tests vocabulary and comprehension of idiomatic expressions.
Such clues offer a richer challenge than simply matching synonyms, requiring solvers to understand the nuances of language. They contribute to the overall enjoyment and educational value of crosswords, expanding vocabulary and reinforcing familiarity with common figures of speech. Historically, cryptic crosswords, originating in the UK, have favored this more complex clue structure, contributing to the ongoing popularity of these puzzles.
