Oikos

''Oikos'' (Ancient Greek: (pronunciation oi•kos ; plural: ) was, in Ancient Greece, two related but distinct concepts: the family and the family's house. Its meaning shifted even within texts.

The ''oikos'' was the basic unit of society in most Greek city-states. In normal Attic usage the ''oikos'', in the context of families, referred to a line of descent from father to son from generation to generation. Alternatively, as Aristotle used it in his ''Politics'', the term was sometimes used to refer to everybody living in a given house. Thus, the head of the ''oikos'', along with his immediate family and his slaves, would all be encompassed. Large ''oikoi'' also had farms that were usually tended by the slaves, which were also the basic agricultural unit of the ancient Greek economy. Provided by Wikipedia
