Abstract
This research analyzes how Japanese compound verbs are treated in educational materials used at a foreign language university in Vietnam. Specifically, this research examines the polysemic compound verb stems -komu, -dasu, -ageru/agaru from the perspective of both frequency and semantic use. It was found that while -dasu occurs relatively frequently, the verb stems -komu and -ageru/agaru occur too infrequently. Additionally, all of these verb stems were hardly ever shown in forms expressing grammatical aspect. The results suggests a need for educational materials to address the expression of aspect using compound verbs, and for students to be encouraged to use them.
