The word 'abruptly-fired' is a compound formed from 'abruptly' and 'fired.' 'Abruptly' comes from Latin 'abruptus' meaning 'broken off,' and 'fired' is the past participle of 'fire' meaning 'to dismiss from a job.'

'Abruptly' entered English from Latin via Old French, and 'fired' as a term for dismissal became common in the 19th century. The compound 'abruptly-fired' is a modern formation.

Initially, 'abruptly' meant 'suddenly' and 'fired' meant 'dismissed.' The compound now specifically refers to being dismissed from a job suddenly and without warning.
