Sheep
noun
The kanji and the word are exactly the same. That means they share meanings as well.
ひつじ
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: Imagine a sheep fighting with Jesus. The first thing it does is hits Jesus (ひつじ) in the stomach with its fists, then hits Jesus again with its horns. Try to imagine this playing out, with an announcer calling the shots as well.
この羊の毛は白いです。
This sheep's fur is white.
今夜は羊のカレーにしましょう。
Let's make mutton curry tonight.
うちには子羊と子牛が両方います。
We have both lamb and calves.
