Lexical Generalizations

Horizontal Generalizations

Lexical rules

If there is a grammatical word described by D then the corresponding words E’ are also grammatical

Lexical Generalizations

Lexical principles

If a word is described by D, then it is also described by E

Complex vs type antecedents

Outline

with MLR

Basic Lexicon

Lexicon external to the theory

Lexicon internal to the theory

Basic Lexicon - Lexicon external to the theory

Extra set of descriptions of word objects

G = <Σ, Θ, L>

Basic Lexicon - Lexicon internal to the theory

Ordinary implicational constraint on word objects

Word Principle

word D1 V D2 V…V Dn

Outline

with MLR

Extending the Lexicon

MLR – Meta-Level Lexical Rules (lexical entries)

DLR – Description-Level Level Rules (word objects)

Extending the Lexicon with MLR

R = {r1,…rn} (binary relations)

B = {β1… β n} (base lexical entries)

L: (full set of lexical entries)

for all λ in L and r in R such that r(λ,φ) in L

Extending the Lexicon with DLR

Binary relations between word objects

Integration of lexical rules at the same level as the other grammatical constraints

Change the Signature

Outline

with MLR

Open Questions

Distinguishing between lexical and structural information

Status of the input of the lexical rule

“Phantom” lexical entries
