Taro

Taro is a root vegetable. It is the most widely cultivated species of several plants in the family Araceae that are used as vegetables for their corms, leaves, stems and petioles. Taro corms are a food staple in African, Oceanic, East Asian, Southeast Asian and South Asian cultures (similar to yams). Taro is believed to be one of the earliest cultivated plants.[citation needed] The English term taro was borrowed from the Māori language when Captain Cook first observed Colocasia plantations in New Zealand in 1769. The form taro or talo is widespread among Polynesian languages: taro in Tahitian; talo in Samoan and Tongan; kalo in Hawaiian; taʻo in Marquesan. All these forms originate from Proto-Polynesian *talo, which itself descended from Proto-Oceanic *talos (cf. dalo in Fijian) and Proto-Austronesian *tales (cf. taleus in Sundanese & tales in Javanese). However, irregularity in sound correspondences among the cognate forms in Austronesian suggests that the term may have been borrowed and spread from an Austroasiatic language perhaps in Borneo (cf. proto-Mon-Khmer *t2rawʔ, Khasi shriew, Khmu sroʔ, Mlabri kwaaj,...).
