lemma etymology

Etymology

The word "lemma" has its origins in ancient Greek:

  • Lemma (λήμμα): "thing taken," "assumption," "premise"

Meaning

In mathematics, a lemma is a proposition that is proven as an intermediate step in the proof of a larger theorem. Lemmas are typically used to break down complex proofs into smaller, more manageable chunks.

Origin

The term "lemma" was first used in mathematics by the ancient Greek mathematician Euclid (c. 300 BC) in his influential work, "The Elements." Euclid used lemmas to assist in the proofs of his geometrical theorems.
