robust
💪 健 (healthy) + 壮 (strong/stout) = robust, sturdy build
健 means healthy or strong, as in 健康 (health); 壮 means stout or strong, as in 壮大 (grow strong). Together: a body or structure that is robust and sturdy. 壮 sounds like the zhuàng in this word.
壮 — 爿 (bed/plank, phonetic) + 士 (scholar/warrior)
A semantic-phonetic compound. 士 ('warrior, man') gives the meaning of strength and vigor, while 爿 ('plank, bed') supplies the sound. Originally describing a robust, sturdy man, it broadened to mean 'strong, robust, magnificent' in general.
