bandana

Bandana comes from Hindi बंधन (bandhan, "the act of binding, a bond"), which traces back to Sanskrit बध्नाति (badhnāti, "he binds"), and ultimately to the Proto-Indo-European root *bʰendʰ-, "to bind, bond."

The word entered English as a borrowing from Hindi, keeping close to its root meaning of binding or tying, since a bandana is fundamentally a cloth defined by how it's tied.

Bandana is a doublet of "bind" — both descend from the same Proto-Indo-European root *bʰendʰ-, meaning they're two branches of the same ancient word for tying things together.
