An inner enclave is a part of a country that is surrounded on all sides by a part of another country. If the enclosed part belongs to a country that is not definitively bounded and surrounded by another country, then it is called the inner pocket of the country that surrounds it and the outer pocket of the country that owns it. A semi-detached enclave is the part of a country that can only be reached by land by crossing another country.
The pocket of the earth is its entrance, that is, the place from which one enters it, and the hole through which the head comes out of the garment is called a pocket, as well as the bag that penetrates the garment and inside which one’s things are placed. The entanglement of the thing is to take it from its sides.
The word enclave is French from the verb enclaver from the Latin vernacular, inclāvāre, meaning to close. Exclave is a generative English, similar to the French word.
The French word enclave is synonymous with the Arabic haram in some cases.
