Yoruba riddles (àlọ́) are word puzzles traditionally shared in evenings. Formula: “Àlọ́ ó!” (Here is a riddle!) Response: “Àlọ́!” Riddler describes something for others to guess.

Example: “A tiny house full of meat” – answer: groundnut/peanut. Riddles test observation, knowledge, and quick thinking. Children learn through play; elders demonstrate wisdom.

Riddles preserve cultural knowledge – they reference plants, animals, tools, and customs. Modernization reduces riddling practice, but it remains in some families and cultural events. Entertainment with educational value.
