'sporadically-supervised' originates from the combination of 'sporadic' and 'supervised'. 'Sporadic' comes from the Medieval Latin 'sporadicus', meaning 'scattered', and 'supervised' is derived from the Latin 'supervidere', where 'super-' meant 'over' and 'videre' meant 'to see'.

'Sporadicus' transformed into the English word 'sporadic', and 'supervidere' evolved into 'supervise', eventually forming the compound adjective 'sporadically-supervised'.

Initially, 'sporadic' meant 'scattered or isolated', and 'supervised' meant 'overseen'. Together, they evolved to describe something that is overseen in an irregular manner.
