▲In [[lexicography]] "lemma" refers to a headword or heading in any kind of dictionary, encyclopaedia, or commentary. So, for example, the lemma of this article is "Lemma (linguistics)".

▲In [[morphology (linguistics)|morphology]], a ''lemma'' is the canonical form of a [[lexeme]]. ''Lexeme'', in this context, refers to the set of all the forms that have the same meaning, and ''lemma'' refers to the particular form that is chosen by convention to represent the lexeme. Lemmas have special significance in highly [[inflection|inflected languages]] such as [[Czech language|Czech]]. In this sense, a ''lemma'' can also be called a '''citation form'''.

▲In [[psycholinguistics]], the terms ''lemma'' has a more restricted use: it is an abstract form of a word that is used in speech production. In the best accepted psycholinguistic models, speech production has several stages, and the ''lemma'' occurs after the word has been selected mentally, but before any information has been accessed about the sounds in it (and thus before the word can be pronounced). It therefore contains information concerning only [[Meaning (linguistics)|meaning]] and the relation of this word to others in the sentence.
