The primary purpose of this paper is to investigate the relation between intentionality and affectedness. Specifically, I make a semantic generalization called the Complementarity of Intentionality and Affectedness (CIA), which states that intentionality and affectedness cannot be entailed in a minimal accomplishment predicate (the combination of a verb and its complement(s) which is a causative accomplishment) at the same time. This mutual exclusivity of entailments of intentionality and affectedness is observed in Korean accomplishment predicates, which have multiple readings in which either the subject is necessarily intentional or the patient is necessarily affected, but not both. After the introduction of the CIA, I argue that English conative alternations are an instance of the CIA: The conative constructions (e.g. He kicked at the ball) entail intentionality, but not affectedness; on the contrary the corresponding transitive verb constructions (e.g. He kicked the ball) entail affectedness, but not intentionality. Finally, I
