To Shine At
To Shine On
intransitive verb, godan verb
The kanji is distinction. To distinct something would be nice, but this is used more like to shine at or to shine on, like when a light shines on someone on a stage, distinguishing them from everyone else.
The reading of the kanji is actually the same as the reading for this word, making things easy (both on'yomi and kun'yomi are さ).
暗い部屋に光が差しています。
Light is shining into the dark room.
よく日が差す部屋に変えてもらえませんか。
Can you change the room to one that has bright sunshine?
窓の外を見ると、もう雨が上がって薄日が差していた。
When I looked outside the window, the rain had already stopped and a soft light was shining through.
