灯(ひ)light, lamp, torch

息(いき)を吹(ふ)きかけて蝋燭(ろうそく)の灯(ひ)を消(け)す。

I blow on the candle to extinguish its light.

ライターでロウソクに灯(ひ)をともしました。

I lit the candle's light with a lighter.

もう夕方(ゆうがた)なので、そろそろ街(まち)に灯(ひ)がともるでしょう。

Since it's already evening, the lights in the city will soon be lit.

伝統(でんとう)の灯(ひ)を絶(た)やそうものなら、先祖(せんぞ)たちに怒(おこ)られてしまうだろう。

If we were to extinguish the light of tradition, we would probably anger our ancestors.

停電(ていでん)して真(ま)っ暗(くら)です。せめてロウソクがあれば灯(ひ)をともせるのに…。

The power outage has made everything pitch black. If only I had a candle, I could light its light up...
