Meaning & readings

oil, fat

On’yomi ユ、ユウ
Kun’yomi あぶら

Origin

The character 油 combines water (the left component 氵, which classifies liquids) with the sound component 由 on the right. The water radical makes sense because oil and fat are liquid or oily substances. The 由 component doesn't contribute a meaning — it's there to hint at the character's pronunciation. Together, these parts create a character that means oil or fat, something slippery and liquid that flows like water.
