Tips

register

枯 is more classical and literary than 干 (gān, dry) or 干枯 (gānkū, dried up). It often appears in poetry and formal writing to evoke desolation or the passage of time, as in 枯木 (withered wood) and 枯井 (dried-up well).

Components

radical

木 mù

tree; wood

Left tree radical - pictograph of a tree. It marks 枯 as belonging to the tree family but specifically a tree in decline: dried out, leafless, dead-standing. The pairing with "old" on the right is one of the cleanest mnemonics in the language - the old tree withers.

phonetic

古 gǔ

old; ancient

Right 古 supplies the sound - gǔ drifting to kū through historical k-onset alternation. It also reinforces the meaning: an old tree is a withered tree. 古 (ten generations of mouths) pictures something so old it has dried out. Same phonetic in 苦 bitter, 故 reason.
