WARD  , that which

guards or watches and that which is guarded or watched . The word is a doublet of " guard," which was adapted from the French comparatively late into English . Both are to be referred to the Teutonic root war-, to protect, defend, cf . " wary," " warn," " beware," O . Eng. weard, Ger. warten, &c., and the English " guardian," " garrison," &c . The principal applications of the term are, in architecture, to the inner courts of a fortified place; at Windsor Castle they are called the upper and lower wards (see BAILEY, CASTLE) ; to a ridge of metal inside a lock blocking the passage of any key which has not a corresponding slot into which the ridge fits, the slot in the key being also called " ward " (see LOCKS) . Another branch of meaning is to be found in the use of the word for a division into which a borough is divided for the purpose of election of councillors, or a parish for election of guardians . It was also the term used as equivalent to " hundred " in Northumberland and Cumberland . To this branch belongs the use for the various large or small separate rooms in a hospital, asylum, &c., where patients are received and treated . The most general meaning of the word is for a minor or person who is under a guardianship (see INFANT, MARRIAGE and ROMAN LAW) .
