Northcote W. Thomas, [2] "Properly speaking taboo includes only a) the sacred (or unclean) character of persons or things, b) the kind of prohibition which results from this character, and c) the sanctity (or uncleanliness) which results from a violation of the prohibition. The converse of taboo in Polynesia is 'noa' and allied forms which mean 'general' or 'common' . . .
