'sporadically' originates from Greek, specifically the word 'sporadikos,' where 'spora' meant 'scattered.' 'Recorded' comes from Latin, specifically the word 'recordari,' where 're-' meant 'again' and 'cordis' meant 'heart.'

'sporadically' changed from the Greek word 'sporadikos' and eventually became the modern English word 'sporadic.' 'Recorded' transformed from the Latin word 'recordari' and eventually became the modern English word 'record.'

Initially, 'sporadically' meant 'scattered or dispersed,' and 'recorded' meant 'to remember or recall.' Over time, 'sporadically-recorded' evolved to mean 'recorded at irregular intervals.'
