'erratically-stalled' originates from the combination of 'erratic' and 'stalled'. 'Erratic' comes from Latin 'erraticus', meaning 'wandering', and 'stalled' is derived from the Old English 'steall', meaning 'place' or 'position'.

'Erraticus' transformed into the Middle English 'erratik', and 'steall' evolved into the modern English 'stall', eventually forming the compound adjective 'erratically-stalled'.

Initially, 'erratic' meant 'wandering' or 'roaming', and 'stall' meant 'place'. Over time, 'erratically-stalled' evolved to describe something that stops unpredictably.
