The name Robert is a Germanic given name, from hrod "fame" and beraht "bright". It is also in use as a surname.

After becoming widely used in Continental Europe it entered England in its Old French form Robert, where an Old English cognate form (Hrēodbēorht, Hrodberht, Hrēodbēorð, Hrœdbœrð, Hrœdberð) had existed before the Norman Conquest. The feminine version is Roberta. The Italian form is Roberto.

In Italy during the Second World War, the form of the name, Roberto, briefly acquired a new meaning derived from, and referring to the Rome-Berlin-Tokyo Axis.

A house is a building or structure that has the ability to be occupied for habitation by humans or other creatures. The term house includes many kinds of dwellings ranging from rudimentary huts of nomadic tribes to complex structures composed of many systems.English-speaking people generally call any building they routinely occupy "home".

The social unit that lives in a house is known as a household. Most commonly, a household is a family unit of some kind, though households may be other social groups, organizations or individuals.

The English word house derives directly from Old English Hus meaning "dwelling, shelter, home, house," which in turn derives from Proto-Germanic Khusan (reconstructed by etymological analysis) which is of unknown origin. The house itself gave rise to the letter 'B' through an early Proto-Semitic hieroglyphic symbol depicting a house. The symbol was called "bayt", "bet" or "beth" in various related languages, and became beta, the Greek letter, before it was used by the Romans.
