Water
noun
The kanji and the word are exactly the same. That means they share meanings as well.
みず
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: Be sure you always carry water when visiting the me zoo (みず). That's a zoo with rows and rows of cages of... me. And I'm thirsty!
水かジュースをもらえますか。
Can I get water or juice?
川の水はきれいなエメラルドグリーンだった。
The river water was a beautiful emerald green.
ふつうの水じゃなくて、ふじ山の水をもらえますか?
May I have some water from Mt. Fuji instead of ordinary water?
