A Word Form Record is a lexical record about a single word form.

    • lexical entry Information about individual words [q.v.] that must be stipulated is put into the lexicon [q.v.] in the form of descriptions that we call lexical entries. They are ordered pairs, consisting of a phonological form (description) and partial feature structure description. Fully resolved lexical sequences [q.v.] consistent with lexical entries can serve as the INPUT values to lexical rules [q.v.].
    • lexical rule Lexical rules are one of the mechanisms (along with the type type hierarchy [q.v.]) used to capture generalizations within the lexicon. Families of related words - such as the different inflectional forms of a verb - can be derived from a single lexical entry [q.v.] by means of lexical rules. We formalize lexical rules as a type of feature structure with features INPUT and OUTPUT. There are three sybtypes of lexical rules: derivational (relating lexemes [q.v.] to lexemes), inflectional (relation lexemes to words [q.v.]), and post-inflectional (relating words to words).
    • lexical rule instantiation Our lexical rules [q.v.] are descriptions, specifying the value of some features and leaving others unspecified. A lexical rule instantiation is a fully resolved feature structure that is consistent with the specification of some lexical rule.
    • lexical sequence Ordered pairs that can serve as the INPUT and OUTPUT values of lexical rules [q.v.] are called lexical sequences. They consist of a phonological form and a fully resolved feature structure.
    • lexicon The list of all words [q.v.] (or lexemes [q.v.]) of a language is called its 'lexicon'. The lexicon is the repository of all idiosyncratic information about particular words including syntactic, semantic, and phonological information. In some theories of grammar, the lexicon can also contain a great deal more systematic information organized by a type hierarchy [q.v.] and/or lexical rules.
