'abruptly-guided' is a compound word formed from 'abruptly' and 'guided'. 'Abruptly' originates from Latin, specifically the word 'abruptus', where 'ab-' meant 'off' and 'rumpere' meant 'to break'. 'Guided' comes from Old French 'guider', meaning 'to lead or direct'.

'Abruptly' changed from the Latin word 'abruptus' and eventually became the modern English word 'abruptly'. 'Guided' evolved from the Old French 'guider' to the modern English 'guided'.

Initially, 'abruptly' meant 'broken off suddenly', but over time it evolved into its current meaning of 'suddenly'. 'Guided' has largely retained its original meaning of 'directed or led'.
