'intermittently' originates from Latin, specifically the word 'intermittere,' where 'inter-' meant 'between' and 'mittere' meant 'to send.' 'Produced' comes from Latin 'producere,' where 'pro-' meant 'forward' and 'ducere' meant 'to lead.'

'Intermittently' changed from the Latin word 'intermittere' and eventually became the modern English word 'intermittent.' 'Produced' evolved from the Latin 'producere' through Old French 'produire' to modern English 'produce.'

Initially, 'intermittently' meant 'to send between,' but over time it evolved into its current meaning of 'occurring at irregular intervals.' 'Produced' has largely retained its original meaning of 'to bring forth or create.'
