Genoa is sewn into the word jeans
An English contract dated 15 June 1580 mentions a "merchant of Jeane", a merchant of Genoa — Genova in Italian. The Ligurian port's cloth, sturdy and cheap, had been valued in English trade since the sixteenth century, and the Republic's navy used it to fit out ships and dress its sailors. From the French bleu de Gênes, the blue of Genoa, English drew the word jeans. By the time Jacob Davis and Levi Strauss patented the modern trousers, between 1871 and 1873, the city's name was already stitched into the word.
