  1. Compound: In linguistics, a compound is a lexeme that consists of more than one stem. Compounding or composition is the process of word formation that creates compound lexemes. That is, in familiar terms, compounding occurs when two or more words are joined together to make them one word. The meaning of the compound may be very different from the meanings of its components in isolation.
    • also known as 合成词
  2. Compound when applied to a human habitat refers to a cluster of buildings in an enclosure, having a shared or associated purpose, such as the houses of an extended family. The enclosure may be a wall, a fence, a hedge or some other structure, or it may be formed by the buildings themselves, when they are built around an open area or joined together.
    • also known as Компаунд
  3. Compound: In military science, a compound is a type of fortification made up of walls or fences surrounding several buildings in the center of a large piece of land. The walls can either serve the purpose of being tall, thick, and impenetrable, in which case they would be made of wood, stone, or some other like substance; or dangerous to attempt to scale, in which case they could be made of barbed wire or electrified. Compounds can be designed to double as living spaces and military structures in the middle of hostile territory or as a military area within a country's territory; they are also used by the extremely wealthy, powerful, paranoid or criminal to protect against threats to themselves or their property.
  4. Compound: A migrant worker compound is a key institution in a system such as that which regulated labour on mines in South Africa from the later nineteenth century. The tightly controlled closed compound which came to typify the phenomenon in that country originated on the diamond mines of Kimberley from about 1885 and was later replicated on the gold mines. This labour arrangement, regulating the flow of male workers from rural homes in Bantustans or Homelands to the mines and jobs in urban settings generally, became one of the major cogs in the apartheid state. The single-sex hostels that became flash points for unrest in the last years of apartheid were a later form of compound.
  5. Compound: A substance formed by chemical union of two or more elements or ingredients in definite proportion by weight.
