A lexical unit is a conventionalized linguistic expression that constitutes an identifiable unit of the lexicon and is associated with a relatively stable pairing of formal realization and lexical meaning ^[1]. It may be realized as a single lexeme or as a fixed or semi-fixed multiword expression, provided that the expression is treated as a stored and describable lexical entity rather than as a freely generated combination of independent words ^[1][2]. A lexical unit may have inflectional variants and may exhibit syntactic, morphological, semantic, collocational, and pragmatic properties; these properties form part of its lexicographic description ^[1]. The term is broader than word form, which denotes a particular orthographic or phonological realization, and may be broader than lexeme, which commonly denotes an abstract vocabulary item encompassing its inflected forms; lexical units can therefore include phraseological expressions whose lexical status is not reducible to a single lexeme ^[1][2].
