'hopefully' originates from the English word 'hopeful,' which is derived from the Old English word 'hopian,' meaning 'to wish or expect.'

'hopeful' changed from the Old English word 'hopian' and eventually became the modern English word 'hopeful,' with 'hopefully' as its adverbial form.

Initially, it meant 'full of hope,' but over time it evolved into its current meaning of 'in a hopeful manner.'
