CHAKKA

The name "Jack fruit" is derived from the Portuguese Jaca,^[4] which in turn, is derived from the Malayalam language term, Chakka.The Portuguese first arrived in India at Cochin on the Malabar Coast. The Malayalam name Chakka was recorded by Hendrik van Rheede (1678–1703) in the Hortus Malabaricus, vol. iii in Latin. Henry Yule translated the book in Jordanus Catalani's (1678–1703) Mirabilia Descripta: The Wonders of the East.
The fruit is called a variety of names around the world. The common English name jackfruit is thought to derive from the Malayalam chakka or cakkai via the Portuguese jaca.^[5] This name is used by the physician and naturalist Garcia de Orta in his 1563 book Colóquios dos simples e drogas da India.^[7][8] A botanist, Ralph Randles Stewart suggests that it was named after William Jack (1795–1822), a Scottish botanist who worked for the East India Company in Bengal, Sumatra and Malaysia.^[9] This is unlikely, as the fruit was called a "Jack" in English before William Jack was born: for instance, in Dampier's 1699 A new voyage round the world
