Dictionaries are mines whose word-gems encapsulate centuries of language history and cultural traditions; they are store-houses of meanings and uses, 'lamp genies' to be set free at the very moment readers set their eyes on their entries.This book is an attempt to free such lamp genies, by discussing the role of dictionaries in the identification and expression of cultural aspects in language, with special reference to English. As such, its eleven chapters have been arranged to focus on general, genre-specific, monolingual and bilingual lexicography, both from a diachronic and a synchronic perspective.The book will be of use to lexicographers and lexicologists, as well as to corpus linguists, historical and contemporary English scholars, students of English, and anybody interested in the juice of culture(s) that can be fruitfully extracted from dictionary entries.
