'suddenly-ceased' is a compound word formed from 'suddenly' and 'ceased'. 'Suddenly' originates from Middle English 'sodein', from Old French 'soudain', from Latin 'subitaneus', meaning 'unexpected'. 'Ceased' comes from Old French 'cesser', from Latin 'cessare', meaning 'to stop'.

'suddenly' evolved from the Old French 'soudain', while 'ceased' evolved from the Old French 'cesser'. The combination of these words into 'suddenly-ceased' is a modern English construct.

Initially, 'suddenly' meant 'unexpectedly', and 'ceased' meant 'to stop'. The combination retains the original meanings, emphasizing an abrupt stop.
