Left half-tree element — simplified from
爿, originally a vertical wooden plank or bed-post (the left half of
木 split down the middle). In traditional
將 this piece was both phonetic (qiáng drifted to jiāng) and faintly semantic (a wooden support). It survives as the left side of
状,
壮,
床 — all carrying a faint plank or bed sense.
