Meaning & readings

lumber, log, timber, wood, materials, ingredients, talent

On’yomi ザイ
Nanori き、さい

Origin

The character combines wood (), the left component, with a sound hint () on the right that suggests how to pronounce it. Since wood is the meaningful part, the character naturally came to mean timber, lumber, and materials made from wood. The right side doesn't add a separate meaning—it's there mainly to guide pronunciation, while the wooden radical on the left carries all the semantic weight of what the character represents.
