Transitive Verb
noun
Remember how 自動詞 was "intransitive verb"? Intransitive verbs are when something just happens. You aren't doing the action to them. This word, however, is the other kind. A transitive verb is when you are directly doing something to something else. That's why it has other in there, because it's a verb (動詞) you do to another thing, directly.
たどうし
This is a jukugo word, which usually means on'yomi readings from the kanji. If you know the readings of your kanji you'll know how to read this as well.

Is memorization the only way to learn if the verb is transitive or intransitive?
