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.

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.
