  1. lemma

    A lemma is a proposition or statement in logic or mathematics that is used to help prove a larger theorem. It is a preliminary, subsidiary, or intermediate theorem in an argument or proof. While not typically the main focus or end goal, a lemma is crucial for the logical progression towards a more significant theorem or conclusion. Lemmas are often used multiple times in proving a single overarching theorem.

Webster Dictionary

    a preliminary or auxiliary proposition demonstrated or accepted for immediate use in the demonstration of some other proposition, as in mathematics or logic

  2. Etymology: [L. lemma, Gr. lh^mma anything received, an assumption or premise taken for granted, fr. lamba`nein to take, assume. Cf. Syllable.]


  1. Lemma

    In mathematics, a lemma from the Greek λῆμμα is a proven proposition which is used as a stepping stone to a larger result rather than as a statement of interest by itself. There is no formal distinction between a lemma and a theorem, only one of intention – see Theorem terminology. A good stepping stone leads to many others, so some of the most powerful results in mathematics are known as lemmata, such as Bézout's lemma, Urysohn's lemma, Dehn's lemma, Euclid's lemma, Farkas' lemma, Fatou's lemma, Gauss's lemma, Greendlinger's lemma, Jordan's lemma, Nakayama's lemma, Poincaré's lemma, Riesz's lemma, Schwarz's lemma, Itō's lemma and Zorn's lemma. While these results originally seemed too simple or too technical to warrant independent interest, they have turned out to be central to the theories in which they occur.

Chambers 20th Century Dictionary

  1. Lemma

    lem′a, n. (math.) a preliminary proposition demonstrated for the purpose of being used in a subsequent proposition: sometimes in logic a premise taken for granted: a theme:—pl. Lemm′as, Lemm′ata. [L.,—Gr. lēmmalambanein, to take.]
