While concordances and word lists are the two most usable forms of corpus data, word lists are largely absent from both practitioner awareness and ongoing research in data-driven learning (DDL). This is mainly because word lists work behind the scenes in the design of DDL instruction rather than up front as concordancers do in the hands of learners. Both are instances of DDL in the sense of language patterning exposed with computer software. Examples of these points are elaborated and a proposal is made to integrate word list research within DDL.
