köken: Inherited from Old Spanish fazaña, façaña, from Arabic حَسَنَة (ḥasana, “good deed, alms”), via Andalusian Arabic. Cognate with Portuguese façanha (which may be a borrowing from Hispano-Romance anyway). Coromines and Pascual suggest influence of Old Spanish fazer, from Latin facere. Such a derivation would help explain the voiced /dz/ of the Old Spanish term, already attested with -z- in the 12th…
köken: Formally a nominalization of bedrive (with the verbal noun drift as its second part). Influenced by Middle Low German bedrif and German Betrieb.
