seal

seal (n.1)

"design stamped on wax," early 13c.,
from O.Fr. seel (Fr. sceau), from V.L. *sigellum (cf. It. suggello, Sp. sello; also O.Fris., M.H.G. sigel, Ger. Siegel),
from L. sigillum "small picture, engraved figure, seal," dim. of signum "mark, token" (see sign).
An earlier borrowing directly from Latin is represented by O.E. insigel.
