# Some Frills for the Modal Tic-Tac-Toe of Davies and Isard: Semantics of Predicate Complement Constructions

## Abstract

Predicate complement constructions are a rich source of semantic problems. The semantics of these constructions is explored in the context of the tictac-toe game playing setting of Davies and Isard {1972). Even in this limited setting, the implementations of these constructions are quite nontrivial, suggesting that such restricted settings provide a good testing ground for many key linguistic problems. Descriptive terms: language understanding systems, semantics, game playing, predicate complement constructions, presuppositions.
