1911 Encyclopædia Britannica/Guardian

GUARDIAN, one who guards or defends another, a protector. The O. Fr. guarden, garden, mod. gardien, from guarder, garder, is of Teutonic origin, from the base war-, to protect, cf. O.H. Ger. warten, and Eng. “ward”; thus “guardian” and “warden” are etymologically identical, as are “guard” and “ward”; cf. the use of the correlatives “guardian” and “ward,” i.e. a minor, or person incapable of managing his affairs, under the protection or in the custody of a guardian. For the position of guardians of the poor see Poor Law, and for the legal relations between a guardian and his ward see Infant, Marriage and Roman Law.
