taboo

Etymology and origin of the English word taboo

Formation
Borrowing
Borrowed from
Tongan tabu

Pronunciation

  • IPA: /təˈbuː/, /tæˈbuː/[1]

Etymology

It is borrowed from Tongan tabu (“under prohibition, forbidden”),[2][3][4][5] first used in English by Captain James Cook in 1777, in the account of his voyage to the Friendly Islands (Tonga).[2][5][4] Similar words exist in other Polynesian languages, such as Hawaiian kapu;[2][5] Etymonline doubts the explanation of Tongan tabu from ta “mark” and bu “especially”.[5]

Earliest recorded meaning

Set apart or consecrated for a special purpose; forbidden, inviolable or cursed (1777).[6][4][5][3]

Semantic evolution

In Polynesian languages the word is generally an adjective; its use as a noun and as a verb are English innovations, both found in Cook in 1777.[4][2][6][3] By 1791 the verb meant to forbid something by social influence,[6] and from 1826 the adjective was used figuratively of anything banned by custom or good taste.[6] In 1883 anthropologists extended the noun to similar customs among other peoples.[6]
