On occasion, crossword puzzle crafters will draw on other languages for their answers. But how are you supposed to know whether the answer is in English or something else? You'll have to rely on the clue to tell you. If the wording of the clue references a specific city or country, or if part of the clue is in a foreign language, that's a pretty surefire indicator that your answer should be in that same language [source: Sayles]. Few crossword puzzle enthusiasts are actually fluent in the languages most often found in the clues, but a basic knowledge of articles, verbs and personal titles in some of the more common languages will go a long way. French, Spanish, German and Latin are particularly popular with puzzle crafters.
