To Answer
To Reply, To Respond
intransitive 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 answer so the verb version means to answer.
The reading is the kun'yomi reading as you'd expect with all the hiragana, but luckily that's the reading you learned with the kanji so you should be able to read this.
