sovereign: [13] A sovereign is etymologically someone who is ‘above’ others. The word comes via Old French souverein ‘ruler’, a descendant of Vulgar Latin *superānus. This was derived from the Latin preposition super ‘above’. In the 1490s the term was applied to a gold coin worth 22s 6d (£1.12½), a usage which served as a model in 1817 for its application to a gold coin worth one pound.
