(January 2010) (Learn how and when to remove this template message) </Td> </Tr> <P> A mansion is a large dwelling house . The word itself derives through Old French from the Latin word mansio "dwelling", an abstract noun derived from the verb manere "to dwell". The English word "manse" originally defined a property large enough for the parish priest to maintain himself, but a mansion is no longer self - sustaining in this way (compare a Roman or medieval villa).' Manor' comes from the same root--territorial holdings granted to a lord who would remain there--hence it is easy to see how the word' Mansion' came to have its meaning . </P> <P> Within an ancient Roman city, aristocratic or just wealthy dwellings might be very extensive, and luxurious . Such mansions on one hill in Rome became so extensive that the term palatial was actually derived from the name Palatine hill and is the etymological origin of "palace". Mansions of considerable size and state significance are called palaces . </P>
