Other forms: mansions
A mansion is a very large and impressive house. A country mansion, an eighteenth-century mansion, the mansion has forty rooms.
It always suggests wealth and it usually suggests age. In London, Mansions with a capital M in a block's name — Prince Albert Mansions — means a Victorian or Edwardian block of flats, which is almost the opposite of a single grand house and confuses visitors. Note the Mansion House, the official residence of the Lord Mayor of London, and mansion tax, a political term for a levy on expensive homes.
