The British National Corpus (BNC) is a large, structured collection of written and spoken English from various sources. It was created to provide a comprehensive resource for linguistic research and analysis, representing a wide range of genres, including literature, newspapers, and conversations. The BNC contains over 100 million words, making it one of the most extensive databases of English language usage. Researchers and linguists use the BNC to study language patterns, vocabulary, and grammar. It helps in understanding how English is used in different contexts and regions, contributing to fields like linguistics, language education, and computational linguistics. The corpus is a valuable tool for anyone interested in the English language.
