'[abruptly]' originates from Latin, specifically the word 'abruptus,' where 'ab-' meant 'off' and 'rumpere' meant 'to break.' '[fixed]' originates from Latin, specifically the word 'fixus,' where 'figere' meant 'to fasten.'

'abruptus' transformed into the French word 'abrupt,' and eventually became the modern English word 'abrupt.' 'fixus' transformed into the French word 'fixer,' and eventually became the modern English word 'fix.'

Initially, 'abruptly' meant 'broken off suddenly,' and 'fixed' meant 'fastened securely.' Over time, 'abruptly-fixed' evolved to mean 'suddenly resolved or stabilized.'
