'sporadically' originates from Greek, specifically the word 'sporadikos,' where 'spora' meant 'scattered.' 'Seen' is derived from Old English 'seon,' meaning 'to see.'

'sporadically' changed from the Greek word 'sporadikos' and eventually became the modern English word 'sporadic.' 'Seen' evolved from the Old English 'seon' to its current form.

Initially, 'sporadic' meant 'scattered or dispersed,' but over time it evolved into its current meaning of 'occurring at irregular intervals.'
