0 a form of a word that appears as an entry in a dictionary and is used to represent all the other possible forms. For example, the lemma "build" represents "builds", "building", "built", etc.:
The lemma and form together make up the information associated with the lexical entry for each word in the lexicon.
The lemmatised form is simply a convenient representation of the headword lemma.
During the lemma selection process, semantically and syntactically appropriate lexical items are selected from the mental lexicon.
The first part of the lemma below also follows by construction.
The lemma below states that any two types, that are convertible after an application of small substitutions, have equal interpretations.
We start with a preliminary lemma, which states that proper has indeed the desired effect.
T he next lemma shows how context-sensitive reduction steps are simulated by the second transformation.
The following lemma follows immediately from (2.2) and properties of the norm residue symbol.
