'unhurriedly' originates from the prefix 'un-' meaning 'not' and the word 'hurried,' which comes from the Middle English 'hurrien,' meaning 'to move with haste.'

'hurried' changed from the Middle English word 'hurrien' and eventually became the modern English word 'hurried.'

Initially, it meant 'to move with haste,' but over time it evolved into its current meaning of 'not rushed.'
