'sporadically-stopped' originates from the combination of 'sporadic' and 'stopped'. 'Sporadic' comes from the Medieval Latin 'sporadicus', meaning 'scattered', and 'stopped' is derived from the Old English 'stoppian', meaning 'to block or close'.

'sporadicus' transformed into the English word 'sporadic', and 'stoppian' evolved into 'stop', eventually forming the modern English term 'sporadically-stopped'.

Initially, 'sporadic' meant 'scattered or isolated', and 'stop' meant 'to block or close'. Together, they evolved to describe something that halts irregularly.
