overjoyed

The word 'overjoyed' is a compound adjective formed within English. Its core, 'joy,' entered Middle English from Old French 'joie,' tracing back to the Latin verb 'gaudēre' (to rejoice). The prefix 'over,' of Germanic origin, intensifies the root, conveying a sense of being "excessively" full of joy. The adjectival suffix '-ed' completes the formation, creating a participle-like adjective that describes a state of being overwhelmed with delight. Thus, the literal construction "characterized by excessive joy" perfectly captures the modern sense of extreme happiness.
