silken

From Middle English silken, selken, seolkene, from Old English seolcen, from seolc (“silk”) + -en, from an unattested early Proto-West Germanic borrowing from Latin sēricum, from Ancient Greek σηρικός (sērikós, “silken”), from σήρ (sḗr, “silkworm”) + -ικός (-ikós, “-ic”). Equivalent to silk + -en (“made of”). Cognate with Scots selkin, silkin (“silken”), Icelandic silki (“silken”).
