For teachers and ESL/EFL materials writers, this is a basic 2400-word vocabulary list arranged in
four levels of 300, 600, 1200, and 2400 essential words. Although based on various word
frequency lists, The Learner's Lexicon also includes words chosen to meet the specific needs of
learners surviving and participating in an English-speaking context.
Because of the tremendous variation among learners and their
backgrounds and needs, this lexicon, limited to 2400 words, is based
on a generalized list of words that virtually all learners need
to know, whether child or adult, immigrant or traveller. A close
examination of the list will reveal that the 0-300 level is heavy
with function words and very basic verbs and adjectives, whereas
the number of nouns is more limited. As one progresses through the
list, the proportion of nouns increases as do the number of derivations,
as the learners' ability to express themselves becomes more sophisticated,
and the topics of communication become more numerous and wider.
This lexicon purposefully goes only to the 2400-word level, because
beyond this level, the predictability of the learner's requirements
becomes less and less certain, and more and more diffuse. A more
detailed explanation of the text and its use can be found in the
Introduction link above.
