c.1250, from O.Fr.
humble, earlier
humele, from L.
humilis "lowly, humble," lit. "on the ground," from
humus "earth." Senses of "not self-asserting" and "of low birth or rank" were both in M.E. The verb is c.1380 in the intrans. sense of "to render oneself humble;" 1484 in the trans. sense of "to lower (someone) in dignity."
"Don't be so humble; you're not that great." [Golda Meir]
To
eat humble pie (1830) is from
umble pie (1648), pie made from
umbles "edible inner parts of an animal" (especially deer), considered a low-class food. The similar sense of similar-sounding words (the "h" of
humble was not pronounced then) converged in the pun.
Umbles, meanwhile, is M.E.
numbles "offal" (with loss of
n- through assimilation into preceding article), from O.Fr.
nombles "loin, fillet," from L.
lumulus, dim. of
lumbus "loin."
