… Riddles allow a certain degree of flexibility in their solutions. The audience is expected to think of all possible solutions. Thus aside from providing entertainment while a group goes about their world together, riddles are also perceived as vehicles for basic pedagogy. This teaching is fundamental: riddles employ expressions which allude to one thing but may also call to mind an entirely different thing. To be able to guess a riddle, one must widen his mental capacities for association and comparison, and the perception of basic likenesses and differences of things around him.
