To Be Accompanied By
To Preside Over, To Subdue
transitive verb, ichidan verb
This word consists of kanji with hiragana attached. Because the hiragana ends with an う sound, you know this word is a verb.
The kanji itself means obey, and this verb is transitive, so some of its meanings refer to when you make someone obey you, or in other words to preside over or to subdue. Depending on the context though, it often just means to be accompanied by someone. To help you remember this, imagine that everyone you're accompanied by obeys you!
