surfeit

There is an abundance—you could almost say a surfeit—of English words that derive from the Latin facere, meaning "to do." The connection to facere is fairly obvious for words spelled with "fic," "fac," or "fec," such as sacrifice, benefaction, and infect. For words like stupefy (a modification of Latin stupefacere) and hacienda (originally, in Old Spanish and Latin, facienda) the facere factor is not so apparent. As for surfeit, the "c" was dropped along the path that led from Latin through Anglo-French, where facere became faire and sur- was added to make the verb surfaire, meaning "to overdo." It is the Anglo-French noun surfet ("excess"), however, that Middle English borrowed, eventually settling on the spelling surfeit.
