疲惫
pí bèi · HSK 7
tired
🪫 疲 = sickness radical 疒 + 皮 pí (skin) for sound; 惫 = 备 bèi (prepare) over 心 heart
Both characters carry a body-or-heart part plus a sound clue: 疲 wraps the sickness radical 疒 around 皮 (pí), 惫 stacks 备 (bèi) on the heart 心. Together pí bèi reads as worn-out-down-to-the-heart: exhausted, beaten, drained.
