Fixed expressions, including idioms and proverbs, give language colour, but they also sometimes give language learners headache. Finding the factors that affect, or are related to, the learning of such expressions has been a long standing concern of many researchers and practitioners. This book explores whether, and to what extent, lexical inferencing strategies can predict EFL learners' comprehension and production of English idioms and proverbs. This book may be of interest to foreign language learners and teachers, vocabulary learning researchers and materials developers.
