We hear a lot about Xenophobia in the news at the moment, but what does the word actually mean? Anne Thompson from The Cambridge Greek Lexicon Project explores the true meaning of the word "xenos" (usually translated as foreigner) and shows that the word has many more positive senses than you might think. A "xenos" is not only a foreigner or a stranger but also an ally, a lifelong friend, a guest, and a host. Indeed "xenoi" were protected by Zeus, the king of the gods.
