What is the likely historical relationship between the Greek word sindon and the Indus region?

Greek sindon referred to a fine cloth and is often connected etymologically with Sindh or textiles from the Indus region. Since the Harappan script is unread, it cannot be claimed that Harappans themselves called their cotton “sindon.” The decisive clue is the institution or practice named in the stem. It referred to fine cloth and may preserve an association with textiles from the Indus region fits that evidence because it matches the specific chronology, agency and function contained in the question. A comparison with the alternatives is useful: It was the Harappans’ own deciphered word for cotton, It named an iron weapon and It was a Roman term for rice are genuine historical terms or names, but each belongs to a different office, patron, text, region or sequence. Reading the question as a relationship among person, period, place and institutional purpose prevents that mistake. The supporting source also helps separate later textbook shorthand from the more precise historical formulation. The compact memory link is therefore It referred to fine cloth and may preserve an association with textiles from the Indus region together with the factual context above, not the isolated option letter.
