OK. You’ve heard that term too many times. But still doesn’t know the meaning quite exact, right?
Now here it is
Xenophobia is an intense and/or irrational dislike and sometimes fear of people from other countries. It comes from the Greek words ξένος (xenos), meaning “foreigner,” “stranger,” and φόβος (phobos), meaning “fear.” The term is typically used to describe a fear or dislike of foreigners or of people significantly different from oneself.
