What words are most useful for learners of English? Introducing the New General Service List. Learning vocabulary is a complex process in which the learner needs to acquire both the form and a variety of meanings of a given vocabulary item. General vocabulary lists can assist in the process of learning words by providing common vocabulary items. In response to problems identified in the currently available General Service List, the authors decided to investigate the core English vocabulary with very large language corpora using current corpus linguistics technology.

New resources are being added regularly to the new CASS: Briefings tab above, so check back soon.
