The stars are shining.
You've got some glittery paint on your right shoe.
I’m sure I saw something shining over there.
This word consists of kanji with hiragana attached. Because the hiragana ends with an う sound, you know this word is a verb. The kanji itself means sunlight, so the verb is to shine or to glitter. Just imagine what happens when sunlight hits things!
Remember how you learned the reading for 光? Well this is almost the same thing. Just change the り to る and you'll know this reading!
