What is a bnc number?

A BNC (British National Corpus) number is a unique identifier assigned to a specific word or phrase within the British National Corpus, which is a 100 million word collection of samples of written and spoken language in English. Each word or phrase in the corpus is tagged with a BNC number for easy reference and analysis. Researchers and linguists use these numbers to track language usage patterns, study word frequencies, and conduct various linguistic analyses.
