COBUILD Advanced Dictionary of American English, English/Japanese

COBUILD is a joint research project by Collins, a major British dictionary publisher, and the University of Birmingham. The COBUILD Advanced Learner's English Dictionary, which was developed based on The Bank of English™, a corpus of roughly 650 million words, is an epoch-making dictionary of living English.
Here, we have taken the dictionary of American English unabridged, and added Japanese, including definitions, examples, and explanations of expressions targeted at Japanese learners, creating the first English and English/Japanese COBUILD dictionary.
The full-sentence definitions that are a special feature of COBUILD provide readers with a precise understanding of the meaning of words and phrases, helping them not only to build their vocabulary but giving them mastery of the actual use of expressions and allowing them to express themselves in simple and natural English.
Also, a sound button appears with each word, allowing users to hear the word pronounced correctly by a native English speaker.
