'suddenly-resolved' originates from the combination of 'suddenly' and 'resolved', where 'suddenly' comes from Middle English 'sodein', meaning 'unexpected', and 'resolved' from Latin 'resolvere', meaning 'to loosen or release'.

'suddenly' changed from the Middle English word 'sodeinly' and 'resolved' from the Latin 'resolvere', eventually becoming the modern English word 'suddenly-resolved'.

Initially, 'suddenly' meant 'unexpectedly' and 'resolved' meant 'to loosen or release', but over time it evolved into its current meaning of 'quickly and unexpectedly settled'.
