noun 1) a particular part of speech in English, whose normal function is to name a person, place or thing, ¶1-3-3, ¶11-3-1; 2) a word opposing a nominal by having plural and possessive forms, ¶1-1-3; a n. in this sense is classed by this particular formal criterion — it follows the n. paradigm (declension); a n. is said to have a possessive form, ¶14-1-2, but though the marker belongs on the noun, this morpheme arguably attaches syntactically to the superordinate nominal or noun phrase; a n. may also refer to a certain morpheme (one, body, thing) that combines with either an identifier or an article to form varieties of a pronoun, which has the normal possessive form
