Etymology
The word 'breakup' is a transparent compound formed from two native English elements. The verb 'break' carries its ancient Germanic sense of separating into pieces or ending continuity. The adverbial particle 'up' is used here in a phrasal verb construction to add a sense of completion or finality to the action. Thus, the literal meaning of "to break completely" evolved logically into the modern abstract nouns describing the definitive end of a relationship or the fragmentation of a whole entity. This compounding process is a common and productive method in English for creating new lexical items from existing Germanic roots.
Analysis
Structure: break (to separate) + up (completive particle)
'Break' is from Old English 'brecan' (to shatter, divide), of Proto-Germanic origin. 'Up' is from Old English 'up', 'upp' (upward, completely), also of Proto-Germanic origin. In this compound, 'up' functions as an intensifying or completive particle.
