A home is a place of residence or refuge. When it refers to a building, it is usually a place in which an individual or a family can rest and store personal property. Most modern-day households contain sanitary facilities and a means of preparing food. Animals have their own homes as well, either living in the wild or shared with humans in a domesticated environment. "Home" is also used to refer to the geographical area (whether it be a suburb, town, city or country) in which a person grew up or feels they belong, or it can refer to the native habitat of a wild animal. Sometimes, as an alternative to the definition of "home" as a physical locale ("Home is where you hang your hat"), home may be perceived to have no physical location—instead, home may relate instead to a mental or emotional state of refuge or comfort. Popular sayings along these lines are "Home is where the heart is" or "You can never go home again". There are cultures in which members lack permanent homes, such as with nomadic people.
A mansion is a large dwelling house. U.S. realtors define a mansion as a dwelling of over 8,000 square feet (740 m2). A traditional European mansion was defined as a house which contained a ballroom and tens of bedrooms. Today, however, there is no formal definition beyond being a large and well-appointed house. The word itself derives (through Old French) from the Latin word mansiō ("act of remaining or staying", a verbal noun from manere "to remain" or "to stay".) In the Roman Empire, a mansio was an official stopping place on a Roman road, or via, where cities sprang up, and where the villas of provincial officials came to be placed. The Scots word "manse" originally defined a property large enough for the Minister of the parish to maintain himself, but a mansion is no longer self-sustaining in this way (compare a Roman or medievalvilla). 'Manor' comes from the same root — territorial holdings granted to a lord who would remain there — hence it can be seen how the word 'Mansion' came to have its meaning.
