Kaliningrad is an exclave of Russia, located between Poland and Lithuania.
**Exclave** → It is formed from "ex-" (meaning out of or away from) and "clavis" (meaning key). The word "exclave" refers to a portion of territory that is separated from the main part and is surrounded by foreign territory, thus being 'out of' the main area.
Think of a piece of land that is 'out of' its main territory — 'ex-' means out, and 'clavis' relates to being key or essential, highlighting its separation.
