Riddles designed to measure Spanish-English bilingualism are presented. The riddles are given in three forms: (1) the background material in English with the answer required in Spanish, (2) the background material and answers in English, and (3) only answers given, either in English or Spanish. The riddles are useful as classroom language exercises, and provide opportunities for practicing both oral and reading comprehension. When the answer-only format is used, they function as stimuli for conversation or writing. 9 sample riddles are presented. (RW)
