Lexical Rule Instantiation

A Lexical Rule Instantiation is a Feature Structure that satisfies a Lexical Rule.

• AKA: Lexeme Instantiation Rule, Instantiation Rule.
• Example(s):
  • …
• Counter-Example(s):
  • Inflection Rule,
  • Derivation Rule,
  • Morphological Compounding Rule.
• See: Lexicon, Lexeme, Lexical Semantics, Lexical Unit, Word Formation Process, Morphological Processing, Part-of-Speech, Compound Word Generation Process, Word Sense Disambiguation.

  • QUOTE: The objects that satisfy lexical rules are LEXICAL RULE INSTANTIATIONS. Lexical rule instantiations are fully specified feature structures. They are not, however, models of words or sentences. We incorporate the effect of lexical rules into our construction of models of sentences by using the lexical sequences that are the OUTPUT values of lexical rule instantiations to license word structures. (See Chapter 9 for a formal description of how this works(...)

     Lexical Licensing is defined in terms of lexical sequences that are legitimate outputs of lexical rules. The instances of the type lexical-sequence are defined as follows:

(38) Lexical Sequences:

[math]\displaystyle{ \langle \omega, \phi \rangle }[/math] is a lexical sequence if and only if [math]\displaystyle{ \omega }[/math] is a phonological form (an atom), [math]\displaystyle{ \phi }[/math] is a feature structure, and either:

1. G contains some lexical entry [math]\displaystyle{ \langle d_1, d_2\rangle }[/math] such that [math]\displaystyle{ \omega }[/math] satisfies [math]\displaystyle{ d_1 }[/math] and [math]\displaystyle{ \phi }[/math] satisfies [math]\displaystyle{ d_2 }[/math], or

2. there is some lexical rule instantiation licensed by G (a feature structure of type l-rule) whose OUTPUT value is [math]\displaystyle{ \langle \omega, \phi \rangle }[/math].

 ::* 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.
