Night, Evening
noun
The kanji and the word are exactly the same. That means they share meanings as well.
よる
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: It is the night, but it is your (よる) night.
夜のパリはロマンチックだ。
Paris at night is romantic.
今日の夜ごはんはパスタです。
Today's dinner is pasta.
私は夜に出かけることが多いです。
I often go out at night.
