'intermittently' originates from Latin, specifically the word 'intermittere,' where 'inter-' meant 'between' and 'mittere' meant 'to send.' 'Shown' is the past participle of 'show,' which comes from Old English 'sceawian,' meaning 'to look at or see.'

'intermittently' changed from the Latin word 'intermittere' and eventually became the modern English word 'intermittently.' 'Shown' evolved from the Old English 'sceawian' to the modern English 'show.'

Initially, 'intermittently' meant 'to send between,' but over time it evolved into its current meaning of 'occurring at irregular intervals.' 'Shown' has largely retained its original meaning of 'to display or make visible.'
