-gry puzzle
The -gry puzzle is a popular word puzzle that asks for the third English word that ends with the letters -gry other than angry and hungry. Specific wording varies substantially, but the puzzle has no clear answer, as there are no other common English words that end in -gry. Interpretations of the puzzle suggest it is either an answerless hoax; a trick question; a sincere question asking for an obscure word; or a corruption of a more straightforward puzzle, which may have asked for words containing gry (such as gryphon). Of these, countless trick question variants and obscure English words (or nonce words) have been proposed. The lack of a conclusive answer has ensured the enduring popularity of the puzzle, and it has become one of the most frequently asked word puzzles.
The ultimate origin and original form of the puzzle is unknown, but it was popularized in 1975, starting in the New York area, and has remained popular into the 21st century. Various similar puzzles exist, though these have straightforward answers. The most notable is "words ending in -dous", which has been popular since the 1880s.
