1911 Encyclopædia Britannica/Denizen

DENIZEN (derived through the Fr. from Lat. de intus, “from within,” i.e. as opposed to “foreign”), an alien who obtains by letters patent (ex donatione regis) certain of the privileges of a British subject. He cannot be a member of the privy council or of parliament, or hold any civil or military office of trust, or take a grant of land from the crown. The Naturalization Act 1870 provides that nothing therein contained shall affect the grant of any letters of denization by the sovereign.
