囊

Top cluster centred on the small 口 — the indexing radical, depicting the cinched mouth of a sack tied off with a lid stroke above and a horizontal binding below. Historical components have fused into this 5-stroke knot; treat it as one bag-mouth unit rather than splitting surrounding strokes.

Bottom 襄 supplies the sound — xiāng shifting to náng through nasal alternation. 襄 itself originally pictured someone hoisting and bundling cloth, so as phonetic here it doubles as a faint semantic hint: a heavy sack lifted up. The fullest stroke-block in the character, carrying most of the visual weight.
