There are all sorts of terms used for persons who grow up or live in more than one culture, particularly those children who are raised in a culture different than their parents’ culture. Most of these terms are unknown to people outside of expat life, but many are even unfamiliar to expats. TCK is becoming a pretty well known term, but there are so many subsets of TCKs, depending on what your parents did for a living. This glossary posted by Among Worlds is a great start to getting a handle on all the words to describe those intercultural beings who grew up internationally.
