Breath
noun
The kanji and the word are exactly the same. That means they share meanings as well.
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: You smell someone's icky (いき) breath. It's gross. Your skin crawls and your eyes roll back in your head from the icky, icky smell. You might die.
