'sporadically' originates from Greek, specifically the word 'sporadikos,' where 'spora' meant 'scattered.' 'Available' comes from Old French 'avaler,' meaning 'to be of use.'

'sporadically' changed from the Greek word 'sporadikos' and eventually became the modern English word 'sporadic.' 'Available' evolved from the Old French 'avaler' to the modern English 'available.'

Initially, 'sporadic' meant 'scattered or dispersed,' but over time it evolved into its current meaning of 'occurring at irregular intervals.' 'Available' has largely retained its original meaning of 'being of use or accessible.'
