'intermittently' originates from Latin, specifically the word 'intermittere,' where 'inter-' meant 'between' and 'mittere' meant 'to send.' 'Associated' comes from Latin 'associatus,' where 'ad-' meant 'to' and 'socius' meant 'companion.'

'intermittere' transformed into the Old French word 'intermettre,' and eventually became the modern English word 'intermittent.' 'Associatus' transformed into the Old French word 'associer,' and eventually became the modern English word 'associate.'

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