Light
noun
What makes it bright around here? It's light!
Note: 明かり is mostly used for light coming from a specific source, like a lamp or light bulb. You'll learn a more general word for light in a couple levels.
Since this word has okurigana (hiragana attached to the kanji) you know that it's probably going to be the kun'yomi reading. You already know the reading from the kanji!
女はランプの明かりの下に立った。
The woman stood under the light of the lamp.
この辺は明かりが少ない。
There's not much light around here.
今日は月の明かりだけで、キャンプができそうです。
It seems like we can camp with only the moonlight today.
