funeral home \fu"ner*al home`\, n.
   An establishment, usually commercial, where the bodies of
   dead persons are prepared for viewing before burial or
   cremation; called also funeral parlor, mortuary, funeral
   chapel and informally, undertaker's. The body may or may
   not be preserved by embalming before viewing or burial, and
   in some cases the body is not exposed for viewing, though
   present in a casket. Often, some form of memorial service is
   held for the deceased at the funeral home, where friends and
   relatives may come to pay their respects to the dead, and
   express condolence to the family. The work of preparation of
   the body and many other arrangements related to the funeral
   and burial are carried out by an undertaker or mortician who
   manages the funeral home.
