Expatriate

An expatriate (in abbreviated form, expat) is a person temporarily or permanently residing in a country and culture other than that of the person's upbringing or legal residence. The word comes from the Latin ex (out of) and patria (country, fatherland), and is sometimes misspelled (either unintentionally or intentionally) as ex-patriot or short ex-pat (because of its pronunciation).
