where do the definitions on google come from
Google Dictionary It was believed that, until August 2010, Google used many definitions from Collins COBUILD.[1] COBUILD entries were easy to recognize by their characteristic full-sentence definitions as well as grammar codes such as [N-VAR], which in Google Dictionary went unexplained. In August 2010, a blog site reported that Google Dictionary switched from the Collins COBUILD Advanced Learner's English Dictionary to the Oxford Pocket Dictionary of Current English as its English definitions provider.[2] This report, although close, was not quite accurate, as in fact the content now came from another Oxford dictionary, the Oxford American College Dictionary.[3]
