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.
A house is a building or structure that has the
ability to be occupied for dwelling by human beings
or other creatures. The term house includes many
kinds of different dwellings ranging from rudimentary
huts of nomadic tribes to free standing individual
structures. In some contexts, "house"
may mean the same as dwelling, residence, home,
abode, lodging, accommodation, or housing, among
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 can be other
social groups, such as single persons, or groups
of unrelated individuals. Settled agrarian and industrial
societies are composed of household units living
permanently in housing of various types, according
to a variety of forms of land tenure. English-speaking
people generally call any building they routinely
occupy "home". Many people leave their
houses during the day for work and recreation, and
return to them to sleep and for other activities.
A growing point of interest is the energy consumption
of a house; while many houses in Japan have no insulation
at all, in Europe from 2018 all houses built should
have no energy consumption at all.
