köken: Likely from Old French cisel, from cisoir (with a change in suffix), from Late Latin cīsōrium (“cutting instrument”), ultimately from Latin caedere (“cut”). The /n/ seems to have been taken from pincel (“paintbrush”).
köken: Borrowed from Ottoman Turkish قلم (kalem) (ultimately from Ancient Greek κάλαμος (kálamos)), whence modern Turkish kalem. Doublet of κάλαμος (kálamos) and καλάμι (kalámi).
