11.144

𤯝瘀（於據反說文積血也從疒女厄反於聲也時人呼疒云病脚俗談非典語也經文從水作淤非也淤青泥也）。

𤯝瘀 (於 + 據 fanqie. The Shuowen says: 'Stagnant blood.' It takes 疒 (女 + 厄 fanqie) as semantic and 於 as phonetic. Contemporaries call 疒 the 'illness foot', which is vulgar speech and not classical diction. In the scripture text it is written with 水 as 淤, which is incorrect; 淤 means blue-green mud).
