rump, footprint radical (no. 114)
禸 is a rare kanji with no clear standalone meaning. Its given glosses point to a rump or footprint, but these are likely tied to its role as a radical rather than a word used independently. Treat its meaning as uncertain.
The exact historical development of 禸 is uncertain. It is traditionally listed as a radical associated with footprints or animal tracks, but its pictographic origin is not well established.
The shape 禸 looks like a footprint with a heel and toes: the outer 冂 frames the print, and the inner 厶 suggests the arch. Picture an animal track left in mud.
For ジュウ, imagine a jeweler examining a rare footprint-shaped gem: jew -> ジュウ, and the footprint radical 禸 is the treasure.
