주석

The term lemma is used in text criticism to describe the reading given in the main text, which may be used as a heading in the apparatus itself. This usage connects it to mathematics (where a lemma is a proven proposition used as a step in a proof, a "given") and natural-language processing (where a lemma is the dictionary headword associated with an inflected form in the running text).
