Xenos (from Ancient Greek ξένος (xénos); pl. xenoi) is a word used in the Greek language from Homer onwards. The most standard definition is 'stranger'. However, the word itself can be interpreted to mean different things based upon context, author and period of writing/speaking, signifying such divergent concepts as 'enemy' or 'stranger', a particular hostile interpretation, all the way to 'guest friend', one of the most hallowed concepts in the cultural rules of Greek hospitality.
