What is Longman Dictionary of Contemporary English?
LDOCE is an advanced learner's dictionary that provides clear and accurate definitions, examples, synonyms, antonyms, collocations, idioms, phrasal verbs, grammar notes, register notes and more for over 230,000 words and phrases. It also includes audio pronunciations, pictures, videos, interactive exercises and quizzes to help you improve your vocabulary, pronunciation and grammar skills.
History and editions of LDOCE
LDOCE was first published in 1978 by Longman, a British publisher that specializes in educational books. It was one of the first dictionaries to use corpus linguistics, which is the study of language based on large collections of real texts. By analyzing how words are used in different contexts and genres, LDOCE aims to reflect the natural and authentic English that people speak and write every day.
Since then, LDOCE has been updated and revised several times to keep up with the changes and developments in the English language. The latest edition is the seventh edition, which was released in 2020. It contains over 165,000 examples from the Longman Corpus Network, which covers a wide range of sources such as books, newspapers, magazines, websites, blogs, social media, podcasts and transcripts. It also has an additional 1 million corpus examples on the DVD-ROM version.
Features and benefits of LDOCE
