“The term manerium seems to have come in with the Conqueror, though other derivatives from the Latin verb manere, in particular mansa, mansio, mansiuncula had been freely employed by the scribes of the land-books. But these had as a rule been used as representatives of the English hide, and just for this reason they were incapable of expressing the notion that the Normans desired to express by the word manerium. In its origin that word is but one more name for a house. Throughout the Exeter Domesday the word mansio is used instead of the manerium of the Exchequer record, and even in the Exchequer record we may find these two terms used interchangeably ….” Frederic W. Maitland, Domesday Book and Beyond 108–09 (1921).
