Bandage is a Germanic word that emigrated to France and came back dressed in a French suffix — a linguistic round trip from "bind" to bende to bandage.
A strip of material used to bind a wound or protect an injured part of the body. Also used as a verb meaning to apply such a strip.
From French bandage, from bande (strip, band), from Old French bende, from Proto-Germanic *bindō (a binding), from *bindaną (to bind) Key roots: *bindaną (Proto-Germanic: "to bind, tie"), *bʰendʰ- (Proto-Indo-European: "to bind").
Bandage took a remarkable round trip between languages. The word began as a Germanic root (*bindaną, "to bind"), was borrowed into Old French as bende ("strip"), gained the French suffix -age to become bandage, and then was borrowed back into English. This Germanic-to-French-to-English boomerang is a common pattern — English is full of words that left as rough Germanic roots
