Page "Vulcan (Star Trek)" Paragraph 12

The term for the purge of emotion is Arie ' mnu.

It is stated that it does not translate properly into any Earth language.

In Diane Duane's novel Spock's World, it was suggested that Arie ' mnu closely translates into " passion's mastery ", but that linguist Amanda Grayson, Sarek's wife and Spock's mother, in her work on the universal translator, had mistranslated the Vulcan word to mean " lack of emotions ".
