Meaning

noun the condition of being treated like a god

noun an embodiment of the qualities of a god

noun the elevation of a person (as to the status of a god)

originFrom Middle English deificacion, from Middle French deifier + -acion or borrowed directly from Latin deificātiō(n), from deific(ā) (“deify”) + -tiō(n) (noun suffix), from de(i) (“god”) + -ficō (“make”). By surface analysis, deif(y) + -ication. * In the Christian, theological sense, influenced by the use of deificātiō(n) as Latin translation of Byzantine Greek θέωσις (théōsis).
