This book offers a comprehensive investigation into advanced students' knowledge of vocabulary in their L1 and L2. As a cross-sectional study, it examines the quantitative aspects of students' vocabulary knowledge through parallel tests of upper secondary level vocabulary, specialised vocabulary, and advanced vocabulary in both their L1 and L2. It also, primarily in qualitative terms, investigates students' L1 and L2 knowledge of polysemous words, lexical fields of near synonyms and false friends. Knowledge of derivative forms, idioms, proverbs, idiomatically used prepositions and multi-word verbs offer insights into both the breadth and depth of students' L1 and L2 vocabulary knowledge. Finally, it considers the extent to which students' results can be attributed to differences between inferencing skills in their L1 and L2. In each subfield, the pedagogical implications of the findings are discussed. This book will be of interest to teachers and researchers focusing on the teaching and learning of vocabulary.

The comprehension, retention and production of idiomatic expressions is one of the most difficult areas of the lexicon for second language (L2) learners, even very advanced students, to master. This book investigates this under-researched and interesting aspect of language acquisition, shedding light on both conventional uses of idiomatic expressions as well as creative variant forms. The chapters in the book delve into different aspects of idiomatic mastery: students' comprehension of canonically used idioms in both their first and second language; the effects of multimedia and visualization techniques on learners' comprehension and retention of L2 idioms; students' misinterpretations of L2 idioms; L2 learners' comprehension of creative idiom variants and their use of idioms in free composition writing.
