The aim of the paper is to examine the Korean ditransitive verb juda and deulida in terms of lexical aspect. Even though it is considered to be one of the inherent properties of verbs, the lexical aspect of a verb can be changed according to features of arguments and thematic relations of arguments in the sentence. The verb juda can function as achievement aspect, active achievement aspect or accomplishment aspect depending on the [±concrete]-feature of a direct object and the semantic role of an indirect object. The verb deulida, which is the honorific form of the verb juda, connotes the lexical aspect of achievement, accomplishment and active achievement according to the feature of a direct object.
