Are you a learner of English? If you want to write an article or report for your class, you need to know the vocabulary and grammar used in academic writing. If you don’t know what an “academic text” is, you won’t be able to write a proper paper. That’s why you need the Oxford Learner’s Dictionary of Academic English. It is a dictionary that provides you with the vocabulary and grammar that you need to write an article.

This dictionary provides a deep discussion of Words and Phrases. You can find definitions, synonyms, antonyms, example sentences, and a lot more. So, if you need to write an article, you can look up the words in the dictionary and get the meaning and the grammar.
