köken: From Ancient Greek δυστυχῶς (dustukhôs), from δυστυχής (dustukhḗs) + -ως (-ōs), the former component from δυσ- (dus-, “bad”) + τύχη (túkhē, “luck”) + -ής (-ḗs, “adjectival suffix”).
köken: Equivalent to des (“the (adverb)”) + værre (“worse”). From Old Danish thi vær, from Old Norse því verr, cognate with Norwegian Bokmål dessverre, Swedish tyvärr, dessvärre. In the modern form the old dative thi (still extant as a conjunction) has been replaced by the old genitive des, which is used as an adverb with comparatives.
