The British National Corpus (BNC) is a 100-million-word text corpus of samples of written and spoken English from a wide range of sources. It was compiled as a general corpus (collection of texts) in the field of corpus linguistics. The corpus covers British English of the late twentieth century from a wide variety of genres with the intention that it be a representative sample of spoken and written British English of that time.
