Note

The term lemma is used in text criticism to describe the reading in the text itself (as opposed to those in the apparatus); this usage is distinct from that of mathematics (where a lemma is a major step in a proof) and natural-language processing (where a lemma is the dictionary form associated with an inflected form in the running text).
