Light, Sunlight
noun
The kanji and the word are exactly the same. That means they share meanings as well.
ひかり
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 have a ton of sunlight where you live. This creates heat. With this sunlight heat you're able to make your favorite food in the world: hickory (ひかり) smoked bacon. Mmm, taste that delicious bacon.
カーテンから光が入る。
Light comes in through the curtain.
日の出の光がまぶしい。
The light from the sunrise is dazzling.
夕べの光、見た？きっとUFOだったね。
Did you see that light last night? It was probably a UFO.
