taffeta

Taffeta entered Late Middle English from Old French taffetas, which came from Medieval Latin taffata, itself borrowed from Classical Persian تافته (tāfta), the past participle of تافتن (tāftan).

The facts available don't describe a shift in meaning — only the chain of languages the word passed through on its way into English.

Taffeta is directly related to the Persian verb تافتن (tāftan), from which its ancestor word tāfta was formed.
