A noa-name is a word that replaces a taboo word, generally out of fear that the true name would anger or summon the force or being in question. The term derives from the Polynesian concept of noa , which is the antonym of tapu (from which derives the word taboo) and serves to lift the tapu from a person or object.
A noa-name is sometimes described as a euphemism, [1] though the meaning is more specific; a noa-name is a non-taboo synonym used to avoid bad luck, [1] and replaces a name considered dangerous. [2] The noa-name may be innocuous or flattering, or it may be more accusatory. [3]
the words for left, usually never positively biased, were turned into euphemisms in three language groups (Scandinavian, Greek, and Avestan).
