English language lexicographers monitor and record uses of language and use databases to interrogate a wide range of evidence. They consider both the meaning and usages of words and compile definitions in a structured manner.
Lexicographers writing definitions for English learner dictionaries also take into consideration the difficulties learners have with learning English. Bilingual lexicographers translate words and expressions, rather than defining them.
Lexicographers edit, proofread and check the accuracy of their own and others' text, and perform editorial tasks. They reassess existing entries and use evidence and judgement to identify and consider possible new entries.
