Usage notes 
An enclave is an area surrounded by another area, while an exclave is an area cut off from the main area. An area can be cut off without being surrounded (such as Kaliningrad Oblast, cut off from the rest of Russia by Lithuania, Poland, and the Baltic Sea) hence exclaved without being enclaved, or surrounded without being cut off (such as the Kingdom of Lesotho, enclaved in South Africa, but not exclaved).
