The word "cotton" comes from the Arabic word "qutn" or "qutun". This was the usual word for cotton in medieval Arabic. Marco Polo in chapter 2 in his book, describes a province he calls Khotan in Turkestan, today's Xinjiang, where cotton was grown in abundance. The word entered the Romance languages in the mid-12th century, and English a century later. Cotton fabric was known to the ancient Romans as an import, but cotton was rare in the Romance-speaking lands until imports from the Arabic-speaking lands in the later medieval era at transformatively lowered prices.
