buy แปลว่า

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.
