Tips

history

The character 困 shows a tree 木 enclosed in a box 囗 — a tree confined in a small space. This gives the meanings of being trapped and exhausted.

usage

困 meaning 'sleepy' is very common in daily speech: 我困了 (I'm sleepy). For 'trapped,' it often appears in the passive pattern: 被困.

Components

radical

囗 wéi

enclosure

Big enclosure radical (Kangxi 31) — the outer wall. 困 literally pictures a tree boxed in by walls, unable to grow. From 'penned-in tree' came the meanings 'trapped / hard-pressed / sleepy / exhausted'. Same wall: 国 country, 园 garden, 围 surround, 因 cause.

semantic

木 mù

tree; wood

Tree inside the enclosure. The image is a sapling that cannot spread its roots and branches because the wall pens it in — a perfect ideogram for 'cornered / stuck / exhausted'. The same trapped-tree imagery survives in idioms like 困境 'predicament' and 围困 'besiege'.
