'hastily' originates from Middle English, specifically the word 'hastili,' where 'hast' meant 'speed.' 'Changed' comes from Old French 'changier,' meaning 'to alter or exchange.'

'hastili' transformed into the modern English word 'hastily,' and 'changier' evolved into 'change' in English.

Initially, 'hastily' meant 'with speed,' and 'change' meant 'to alter.' Together, they convey the idea of something altered quickly.
