'abruptly-changed' originates from the combination of 'abruptly' and 'changed', where 'abruptly' comes from Latin 'abruptus', meaning 'broken off', and 'changed' from Old French 'changier', meaning 'to alter'.

'abruptly' changed from the Latin word 'abruptus' and 'changed' from the Old French word 'changier', eventually forming the modern English term 'abruptly-changed'.

Initially, 'abruptly' meant 'broken off', and 'changed' meant 'to alter', but over time they combined to describe a sudden alteration.
