historical usage of taboo

Captain James Cook, the English navigator, explorer, and cartographer, used and defined tabu, taboo (he used both spellings) as “a word of a very comprehensive meaning but [which] in general signifies forbidden,” in an entry in his journal in 1777 during his third voyage when he visited the island of Tongatapu, the main island of the Kingdom of Tonga and the location of its capital.
Tabu is also the variant in some other Polynesian languages of Melanesia and Micronesia. In Maori (the Polynesian language spoken on New Zealand), the form is tapu, which is also the reconstructed Proto-Polynesian form. Hawaiian has the variant kapu (Hawaiian changes Polynesian initial t- to k- ).
Use of tabu, taboo as a noun and verb is only in English: all the Polynesian forms are adjectives.
