Fastidious Has a Disgusting Past

There's nothing offensive about fastidious workmanship, and yet the word fastidious traces to the Latin noun fastidium, meaning "aversion" or "disgust." "Fastidium" itself is probably a combination of the Latin words fastus, meaning "arrogance," and taedium, meaning "irksomeness" or "disgust."("Taedium" also gave us our "tedium.") In keeping with its Latin roots, fastidious once meant "haughty," "disgusting," and "disgusted," although those uses are now archaic or obsolete. The word came to be applied to someone who is squeamish or overly difficult to please, and later, to work which reflects a demanding or precise attitude.
