The General Service List (GSL)
What is the GSL?
The GSL, or General Service List, is a list of words which were chosen because they were thought to be of greatest ‘general’ use to learners of English. How frequently they occur in English was one factor which was considered when selecting the words. The original list was compiled by Michael West in 1953. There were several problems with this list, and it was substantially revised in 1995 by John Bauman and Brent Culligan. Culligan, together with two other researchers, have recently produced a newer version of the GSL called the NGSL (New General Service List).
