To Console

Because the hiragana ends with an う sound, you know this word is a verb. The kanji itself means consolation and the verb vocab version is to console.
Since this word consists of a kanji with hiragana attached, you can bet that it will use the kun'yomi reading. You didn't learn that reading with this kanji, so here's a mnemonic to help you: I'm going to console you for what happened to you. The nag saw (なぐさ) was turned on and buzzed through your leg. What a nagging feeling. You need some consoling.
