köken: Borrowed from Old Church Slavonic дрьзость (drĭzostĭ), as *дёрзость (*djórzostʹ) would be expected. By surface analysis, де́рзый (dérzyj) + -ость (-ostʹ).
köken: From Old Swedish diærver, from Old Norse djarfr, from Proto-Germanic *derbaz. According to Svenska Akademiens ordbok it may be related to the same stem as Old English deorfan ("to work; to act") and Lithuanian dirbti ("to work"), or Ancient Greek τρέφω (tréphō) ("to make solid; to make fat; to feed; to nurture"). Nationalencyklopedins ordbok suggests a relation to German derb ("coarse").
