'hastily' originates from Middle English, specifically the word 'hastily,' where 'hast' meant 'speed.' 'Constructed' comes from Latin, specifically the word 'constructus,' where 'con-' meant 'together' and 'struere' meant 'to build.'

'hastily' changed from the Old English word 'hæstlice' and eventually became the modern English word 'hastily.' 'Constructed' evolved from the Latin 'constructus' through Old French 'construire' and Middle English 'constructen.'

Initially, 'hastily' meant 'with speed,' and 'constructed' meant 'built together.' Over time, 'hastily-constructed' evolved to mean 'built quickly without thorough planning.'
