Light
Lamp
noun
The kanji means lamp, and the noun version means essentially the same thing: a light or a lamp.
While 光 refers to light in an abstract sense and 明かり to the illumination something gives off, 灯り (or sometimes just 灯) refers to a manmade light source — whether a lamp, a candle, or even an indistinct light glimpsed in the distance at night. Compared to more modern terms like ライト, it feels gentler and warmer, and appears more often in poetic or descriptive contexts like novels or songs.
This word uses a kun'yomi reading for 灯 that you haven't learned yet, so here's a mnemonic:
The reading sounds just like 明かり, another light-related word. Makes sense, if you think about it, since a light will make 明かり (あか) when it's lit.
灯りが見える
to be able to see a light
灯りがともる
a light gets lit, a light comes on
灯りが消える
a light goes out
遠くにぽつんと灯りが見える。
A lone light can be seen in the distance.
窓から暖かい灯りが見えた。
A warm light could be seen through the window.
灯りの消えた町は、どこかさびしかった。
The town felt somehow lonely once all the lights had gone out.
その部屋には、小さなロウソクの灯りだけがともっていました。
The room was lit only by the light of a small candle.
