'hastily-resolved' originates from the combination of 'hastily,' derived from the Old English 'hæstlice,' meaning 'with speed,' and 'resolved,' from the Latin 'resolvere,' meaning 'to loosen or release.'

'hastily' evolved from the Old English 'hæstlice,' while 'resolved' came from the Latin 'resolvere,' transforming through Old French 'resolver' to the modern English 'resolve.'

Initially, 'hastily' meant 'with speed,' and 'resolved' meant 'to loosen or release.' Over time, 'resolved' evolved to mean 'settled or decided,' and 'hastily-resolved' now implies a quick, often insufficient resolution.
