'hastily-assessed' originates from the combination of 'hastily' and 'assessed'. 'Hastily' comes from the Old English 'hæst' meaning 'speed' and 'assessed' from the Latin 'assessus', meaning 'to sit beside' or 'to evaluate'.

'Hastily' evolved from the Old English 'hæst' and 'assessed' from the Latin 'assessus', eventually forming the modern English compound adjective 'hastily-assessed'.

Initially, 'hastily' meant 'with speed' and 'assessed' meant 'evaluated'. Together, they convey the idea of a quick evaluation, often lacking depth.
