Husband
noun
The kanji and the word are exactly the same. That means they share meanings as well.
おっと
Since this word is made up of a single kanji, it should use the kun'yomi reading. When learning the kanji, you didn't learn that reading, so here's a mnemonic to help you with this word: Think about your husband even if you don't have one. What's his name? It's Otto (おっと), and he's always leaving you at home because he's working at the auto (おっと) shop.
夫はスポーツが好きです。
My husband likes sports.
夫に聞いてみます。
I'll ask my husband.
私の夫の歯は、とても丈夫です。
My husband has very healthy teeth.
