均 ＝ 土 ＋ 匀
ㄐㄩㄣ · jūn
adj/verb — even, equal, uniform; to level out

字源 FORM — what the parts do

土義earth — the ground being leveled
匀聲yún — gives the shape, worn to jūnevenly spread
{g,k,h}{j,q,x}ITyún → jūn — the {y/j} palatal crossing, tone shifts too
Earth (土) and 匀 (yún): ground raked flat, level all the way across. 說文 calls it 平徧也 — even and everywhere. The sound-piece 匀 already means evenly-spread, so it leans into the meaning while it carries the sound (yún worn to jūn). From leveled earth come 平均、均等 (equal), and 老少均安 (all alike, without exception).

故事 STORY — a scene to remember it by

土（土）耙得勻（匀）——這頭到那頭一樣平，這就是均。
The earth (土) raked even (匀) — flat the same from this end to that; that is 均.
