The program's name combines [[http://en.wikipedia.org/wiki/Greek_language|Greek]] <ref>[[http://en.wiktionary.org/wiki/xen|xen - Wiktionary]]</ref> and [[http://en.wikipedia.org/wiki/Latin|Latin]] <ref>[[http://en.wiktionary.org/wiki/arbor#Latin|arbor Latin - Wiktionary]]</ref> roots to mean "strange or alien tree", as explained by Miller to [[Boris Baczynskyj]] during [[ACM 1984]] <ref>[[Boris Baczynskyj]] (**1985**). //The 15th ACM NACCC Anatomized//.
