Question

I once knew the answer. It was not latin, greek or roman... I just can't remmber

Answer 1

tattoo (1)
"signal," 1688, "signal calling soldiers or sailors to quarters at night," earlier tap-to (1644, in order of Col. Hutchinson to garrison of Nottingham), from Du. taptoe, from tap "faucet of a cask" (see tap (2)) + toe "shut." So called because police used to visit taverns in the evening to shut off the taps of casks. Transf. sense of "drumbeat" is recorded from 1755. Hence, Devil's tattoo "action of idly drumming fingers in irritation or impatience" (1803).

tattoo (2)
"mark the skin with pigment," 1769 (noun and ver, both first attested in writing of Capt. Cook), from a Polynesian noun (e.g. Tahitian and Samoan tatau, Marquesan tatu "puncture, mark made on skin").

taboo
1777 (in Cook's "A Voyage to the Pacific Ocean"), "consecrated, inviolable, forbidden, unclean or cursed," explained in some Englishsources as being from Tongan (Polynesian language of the island of Tonga) ta-bu "sacred," from ta "mark" + bu "especially." But this may be folk etymology, as linguists in the Pacific have reconstructed an irreducable Proto-Polynesian *tapu, from Proto-Oceanic *tabu "sacred, forbidden" (cf. Hawaiian kapu "taboo, prohibition, sacred, holy, consecrated;" Tahitian tapu "restriction, sacred;" Maori tapu "be under ritual restriction, prohibited"). The noun and verb are Eng. innovations first recorded in Cook's book.

Answer 2

Tattoo was originally the Dutch word taptoo, from earlier taptoe, from the phrase Tap Toe.

Taboo is from Tongan "tabu".

Answer 3

1) "Tattoo" is from the Tahitian "tatau", means to mark something twice (ta = hand, u= colour)
2) "Taboo" is from Tongan, "tabu" meaning "prohibited"
