 note = {This quantitative study investigated the necessary elements of a principled vocabulary component that would supplement learners’ textbooks. This study then went on to investigate the receptive vocabulary sizes and textbook target language samples for three intact English communication classes in women’s university in western Tokyo. Using the Vocabulary Size Test（VST）data was collected and participant vocabulary sizes assessed, which were then compared to assigned textbook target language samples run through the Range program. Both the VST and Range utilized the British National Corpus（BNC）as the base-word source. Research questions（RQ）investigated included comparing participant vocabulary size to textbook requirements; whether textbooks implicated gaps in participant /learner vocabulary knowledge; and if any one element of a vocabulary component could best address gaps between participant and textbook vocabulary levels. Indeed, the findings produced evidence regarding the above RQs: discrepancies between participant and textbook vocabulary do exist; the assigned textbook does contribute to gaps in participant/learner vocabulary albeit in a relatively minor role; and, the teaching of affixes would clearly assist in closing the gap between participant vocabulary knowledge and the assigned textbook vocabulary requirements.},
