Components

radical

虫 chóng

insect; worm

Right 虫 - pictograph of a coiled snake or worm, generalised to all insects and small creatures. As the indexing radical it carries the imagery: corrosion is metaphorical worm-action, slowly eating something away. Same radical drives 蛀 (worm-eaten), 蚊 mosquito, 蜂 bee, 蛙 frog.

phonetic

饣 shí

eat; food

Left food radical - three-stroke side form of 食. Here it doubles as phonetic and semantic: the sound shí passes straight through, and the 'eating' meaning is the heart of the character - erosion is gnawing slowly away. Originally written 蝕 with full 食 above 虫.
