Components

radical

艹 cǎo

grass; plant (top radical)

Grass radical on top - also 苦's indexing radical. The original meaning is botanical: a bitter herb (苦菜, 'bitter vegetable'). From the literal taste came the metaphorical 'hardship, suffering.' Same radical in 茶 (tea - also bitter), 草, 花, 药 - every plant lives here.

phonetic

古 gǔ

ancient; old

Bottom 古 supplies the sound: gǔ → kǔ with regular g-/k- velar alternation. Same phonetic anchors 故 (gù), 估 (gū), 姑 (gū), 枯 (kū), 胡 (hú) - recognise the 古 cluster and a wide net of g-/k-/h- readings opens up.
