1610-20; < Frenchbergamote < Italianbergamotta < Ottoman Turkish; compare Mod Turkishbey armudlu literally, bey's pear (beybey + armut pear (< Persian) + -u 3rd singular possessive suffix); Italian form perhaps by association with Bergamo, Bergama, with -otta as alteration to a familiar suffix; the citrus apparently so called from its resemblance to the pear
kind of citrus fruit, 1690s, from Fr. bergamote (17c.), from It. bergamotta, said to have been named for Bergamo, town in Italy, though the town is on the opposite end of the peninsula from where the fruit grows. Probably this is a folk-etymologization from Turkish beg-armudi "prince's pear." Bergamo is Roman Bergamum, from a Celtic or Ligurian berg "mountain," cognate with the identical Gmc. word.
