One form, the lemma
(or citation form), is chosen by convention as the canonical form of a lexeme. The lemma is the form used in dictionaries as an entry's headword
. Other forms of a lexeme are often listed later in the entry if they are uncommon or irregularly inflected.
The notion of the lexeme is central to morphology
the basis for defining other concepts in that field. For example, the difference between inflection
can be stated in terms of lexemes:
- Inflectional rules relate a lexeme to its forms.
- Derivational rules relate a lexeme to another lexeme.
A lexeme belongs to a particular syntactic category
, has a certain meaning
) and, in inflecting languages, has a corresponding inflectional paradigm
. That is, a lexeme in many languages will have many different forms. For example, the lexeme run has a present third person singular
, a present non-third-person singular form run
(which also functions as the past participle
form), a past form ran
, and a present participle running
. (It does not include runner, runners, runnable
etc.) The use of the forms of a lexeme is governed by rules of grammar
. In the case of English verbs such as run, they include subject-verb
agreement and compound tense
rules, which determine the form of a verb that can be used in a given sentence
- The root morpheme is the primary lexical unit of a word, which carries the most significant aspects of semantic content and cannot be reduced to smaller constituents.
- The derivational morphemes carry only derivational information.
- The suffix is composed of all inflectional morphemes, and carries only inflectional information.
The compound root morpheme + derivational morphemes is often called the stem
The decomposition stem + desinence
can then be used to study inflection.
run is here intended to display in small caps
. Software limitations may result in its display either in full-sized capitals (RUN) or in full-sized capitals of a smaller font. Either is regarded as an acceptable substitute for genuine small caps.
