- One who brings up, rear, fosters or nourishes, or is responsible for doing all or one or more than one of these;
- Guardian, patron; one who supervises or is responsible for carrying out improvements;
- One who occupies a central or focal position, who himself gathers people round himself of his own or round whom people gather out themselves;
- Leader, head, chief, or lord; one whose word is obeyed, and whose supremacy or over lordship acknowledged, and who has authority to dispose of men or things;
- Owner ; master.
