'intermittently-sent' originates from the Latin word 'intermittere,' where 'inter-' meant 'between' and 'mittere' meant 'to send.'

'intermittere' transformed into the French word 'intermettre,' and eventually became the modern English word 'intermittent' through Middle English.

Initially, it meant 'to send between intervals,' but over time it evolved into its current meaning of 'sent at irregular intervals.'
