This four volume study and report was undertaken to aid students of English as a second language by encouraging them to make use of fixed expression (cliche) as a nonliteral filler when speaking. Over 135,000 words of natural language were examined and a range fixed expressions were isolated and placed into the categories of interjection, circumlocution, quantification, emphasis, and officialese. The research shows that first-language speakers use a fixed expression once in every five words, which results in a comfortable familiarity with their own language in everyday speech. It is concluded in this report that fixed expressions must be taught to second-language learners to give them further self-assurance when speaking English. (TS)
