[Latin, from Greek lemma a thing taken; in logic, a premise taken for granted; eilem mai , perf. pa . of lamb anō =to take; Fr. lemme .] Math.: An auxiliary proposition, demonstrated on account of its immediate application to some other proposition. The conclusion of the lemma becomes requisite to the demonstration of the main proposition, and, rather than encumber that proposition, a separate demonstration is introduced. The idea of a lemma is, that it is introduced out of its natural place, and this serves to distinguish it from ordinary propositions which, entering in their proper places, are of more or le use in demonstrating subsequent ones. *lěm-mạn, s.
