Dumb crambo is a parlor game and poetic exercise where participants must guess a word that rhymes with a given word through pantomime or gesture, or create verses using rhyming words without using the obvious rhyme. In literary contexts, it refers to verse-making constrained by predetermined rhyme requirements, emphasizing the game-like aspects of poetic composition. This tradition highlights poetry's recreational dimensions and the creative challenge of working within arbitrary constraints, demonstrating how limitation can stimulate inventiveness and how play can generate literary forms.

Dumb crambo is a word game where players rhyme without revealing the word—used in poetry for riddles, puzzles, or playful concealment of meaning.
