noun / adjective
satin
SAT-un/ˈsætn/
A fabric with a smooth lustrous face.
Blue satin drapes in smooth folds that catch the light.

Etymology
Old French satin already named the glossy cloth. Its deeper origin is disputed: the proposed connection to a Chinese port is rejected by the OED, which instead derives it from Latin seta, “silk.”
