The antonym for the word jaded is Refreshed
An antonym is one of two words that have completely different meanings. The two words are opposites of one another. There may be more than one antonym for a term. By the way the opposing meanings are related to one another, antonyms can be divided into three groups. They are gradable antonyms in cases where the two terms have definitions that fall along a continuous spectrum of meaning.
They are complimentary antonyms when their meanings do not fall along a continuum and there is no other linguistic connection between them. They are relational antonyms when the contrast between the two meanings only exists within the context of their relationship.
