Masculine

Since ca. 1400, at first as degen, but also dege, dägen, tägen. Usually derived from Middle French dague, but the origin of the e-vocalism is unclear. An eastern dialectal *degue is possible, but apparently unattested, whereas Czech dýka is considered a borrowing from German. See French dague and Italian daga for more. Probably also related with the family of English dagger. From the 17th century, the sense “dagger” is restricted to Dolch, while Degen comes to refer to longer weapons, especially thrust-oriented dueling swords. By the 18th century it was used of any sword worn as part of a uniform.
