vegetable; dish
菜 is a sound-and-meaning character. 艹, the grass or plant sign at the top, points to edible plants; 采 below supplied the historical sound clue. 采 itself once pictured a hand gathering from a plant, which also makes the whole form memorable, but that visual connection is not the character’s complete scholarly derivation. 菜 is not securely attested in oracle-bone script, so this hand-drawn old-style form shows its established plant-over-采 structure rather than claiming a prehistoric vegetable picture.
