Nation, Paul Kyongho, H Where would general service vocabulary stop and special purposes vocabulary begin? Using frequency, text coverage, and range as criteria, this study looks at the dividing line between a general service vocabulary and a special purposes vocabulary. A general service vocabulary gives a good return for learning up to the 2000 word level and after that a special purposes vocabulary gives a better return for learning effort for those learners going on with special interests. © 1995.
