Meaning & readings

sugar

On’yomi トウ

Origin

This character combines the classifier for grain or rice on the left with a sound hint on the right. The rice radical makes sense because sugar was traditionally made from sugarcane and other plant sources, so characters related to sweet food products use the rice classifier to show they belong in that category. The right side, the character for "Tang," doesn't mean anything in this compound—it just tells you roughly how to pronounce the word. Together, these parts create a character that visually signals "a sweet grain product" while giving you a hint at the pronunciation.
