From Middle English byen, from Old English bycġan (“to buy, pay for, acquire, redeem, ransom, procure, get done, sell”), from Proto-West Germanic buggjan, from Proto-Germanic bugjaną (“to buy”), of uncertain origin. Perhaps from Proto-Indo-European bʰūgʰ- (“to bend”), or from Proto-Indo-European bʰewgʰ- (“to take away, deliver”). Cognate with Scots buy (“to buy, purchase”), obsolete Dutch beugen (“to buy”), Old Saxon buggian, buggean (“to buy”), Old Norse byggja (“to build, settle”), Gothic 𐌱𐌿𐌲𐌾𐌰𐌽 (bugjan, “to buy”). The spelling with “u” is from the Southwest, while the pronunciation with /aɪ/ is from the East Midlands.
