The aim of this paper is to extend the application of a previous analysis of simple honourific expressions to modifier expressions including honourified adjectives. The morphological differences between honourific verbal predicates and adjectival predicates, and the identification of the target of honourification are examined. The author has proposed in previous papers an analysis of Japanese honourific constructions, based on the theories of light verbs and agreement. That proposal was made on the basis of expressions including honourified verbs and nouns. The previously proposed analysis is applied in conjunction with a structure of the adjective modifier construction similar to the relative clause structure.
