   • 1989 December 3, Pam Mitchell, Ronnie Gilbert, “Carrying On The Honorable Tradition Of 'Protest Music'”, in Gay Community News, volume 17, number 21, page 9:

     They were learning to do what in all my years in the music business I never saw — which was women running a record company, women producing concerts, women learning to be engineers, women moving into this absolutely all-male enclave. You never saw a woman in any of those positions, in any of that work except as secretaries and "go-fers".

   • 2014 November 17, Roger Cohen, “The horror! The horror! The trauma of ISIS [print version: International New York Times, 18 November 2014, p. 9]”, in The New York Times‎^[1]:

     What is unbearable, in fact, is the feeling, 13 years after 9/11, that America has been chasing its tail; that, in some whack-a-mole horror show, the quashing of a jihadi enclave here only spurs the sprouting of another there; that the ideology of Al Qaeda is still reverberating through a blocked Arab world whose Sunni-Shia balance (insofar as that went) was upended by the American invasion of Iraq.

   • 2017 May 11, Andy Beckett, “Accelerationism: how a fringe philosophy predicted the future we live in”, in The Guardian‎^[2]:

     Since 2013, he has become a guru for the US-based far-right movement neoreaction, or NRx as it often calls itself. Neoreactionaries believe in the replacement of modern nation-states, democracy and government bureaucracies by authoritarian city states, which on neoreaction blogs sound as much like idealised medieval kingdoms as they do modern enclaves such as Singapore.

3. (computing) An isolated portion of an application's address space, such that data in an enclave can only be accessed by code in the same enclave.
   • 2010, Mike Ebbers, Dino Tonelli, Jason Arnold, Co-locating Transactional and Data Warehouse Workloads on System z, page 245:

     When an enclave spans a system boundary in a sysplex, it is called a multisystem enclave.

Enclaves are generally also exclaves, though exceptions exist (as detailed at list of enclaves and exclaves), and in common speech only the term enclave is used.

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).

• 
  C is A's enclave and B's exclave.
• 
  C is an exclave of B, but not an enclave of A.

A pene-enclave (resp., pene-exclave) is an area that is an enclave "for practical purposes", but does not meet the strict definition. This is a very technical term.

enclave (third-person singular simple present enclaves, present participle enclaving, simple past and past participle enclaved)

1. (transitive) To enclose within a foreign territory.
