Middle English, squeamish, particular, haughty, from Old French fastidieux, from Latin fastīdiōsus, from fastīdium, squeamishness, haughtiness, probably from fastus, disdain.(American Heritage® Dictionary of the English Language, Fourth Edition)
From Latin fastidiosus ("passive: that feels disgust, disdainful, scornful, fastidious; active: that causes disgust, disgusting, loathsome"), from fastidium ("a loathing, aversion, disgust, niceness of taste, daintiness, etc."), perhaps for *fastutidium, from fastus ("disdain, haughtiness, arrogance, disgust") + taedium ("disgust"). Confer French fastidieux. (Wiktionary)
