There are the transitive verbs being causative in its meaning. The transitive morphemes such as ?-as-?, ?-os-?, ?-s-?, ?-se-? contain continuity with the causative morphemes of ?(sa)seru? on the formal characteristics. The transitive morpheme [-as-] is seen as a turning point converting a transitive meaning into a causative meaning. The morphemes such as [-os-, -s-, -se-] are categorized as direct and indirect factor by the influence on objects of a subject, which are the transitive or the causative meaning through the process of the middle stage. As a result, the morpheme [-(sa)seru-] is typically expressed as the causative meaning. We categorize the transitive verbs into three types: typically direct meaning, direct and indirect meaning, indirect meaning as to the intention and the activity of the subject. In summary, we try to induce them to typically be a causative meaning, which is to be realized by ordering, commanding, requesting objects as to the intention of the subject.
