abase

From Late Middle English abaishen, abashen, abaisse, abassen, abesse, abessen (“to be upset; to embarrass; to surprise; to confound; to bend down, stoop; to abase, degrade, disgrace”), from Middle French abaisser, from Old French abaissier, abessier (“to prostrate oneself; to lower, reduce”) (also compare Old French esbahir (“to amaze”), Vulgar Latin abbassiāre (“to lower”)), from a- (prefix indicating movement towards something) (from Latin ad (“toward, to”), ultimately from Proto-Indo-European h₂éd (“at, to”)) + baissier (“to lower”) (from Medieval Latin bassus (“short of stature, low; base”), possibly from Ancient Greek βᾰ́σῐς (bắsĭs, “foot; base, foundation”), ultimately from Proto-Indo-European gʷem- (“to step”)). The spelling of the English word has been influenced by base, thus ostensibly analyzable as a- (“towards”) + base. There exist verb cognates in galloromance languages such as Catalan abaixar (“lower; abase”) and Occitan abaissar, and similar word construction in other romance languages as Spanish abajo (“down, downstairs; below”).
