köken: Inherited from Old Czech cětka, from Proto-Slavic *cęta + -ka, from Gothic 𐌺𐌹𐌽𐍄𐌿𐍃 (kintus), from Latin centum. First attested in the 14th century.
Unknown. Attested since the first half of the 17th century. In view of мисю́рка (misjúrka, “a kind of helmet-armour with a net”), Ukrainian місю́рка (misjúrka, “a kind of helmet-armour with a net; glass-pearl”) apparently borrowed from a Turkic language which changes /b/ to /m/, doublet of би́сер (bíser, “beads, pearls”) or whatever Turkic word that armour name hails from.
