'intermittently-supplied' originates from the combination of 'intermittent' and 'supply'. 'Intermittent' comes from Latin 'intermittere', where 'inter-' meant 'between' and 'mittere' meant 'to send'. 'Supply' comes from Latin 'supplere', where 'sub-' meant 'under' and 'plere' meant 'to fill'.

'Intermittent' changed from the Latin word 'intermittere' and eventually became the modern English word 'intermittent'. 'Supply' transformed from the Latin word 'supplere' and became the modern English word 'supply'.

Initially, 'intermittent' meant 'to send between', but over time it evolved into its current meaning of 'occurring at irregular intervals'. 'Supply' initially meant 'to fill up', and this meaning has largely remained the same in modern usage.
