'intermittently-separated' originates from the combination of 'intermittent' and 'separated'. 'Intermittent' comes from Latin 'intermittere', where 'inter-' meant 'between' and 'mittere' meant 'to send'. 'Separated' comes from Latin 'separatus', the past participle of 'separare', where 'se-' meant 'apart' and 'parare' meant 'to prepare'.

'Intermittent' evolved from the Latin 'intermittere' through Old French 'intermettre', and 'separated' evolved from Latin 'separatus' through Old French 'separer'.

Initially, 'intermittent' meant 'to send between', and 'separated' meant 'to prepare apart'. Over time, 'intermittently-separated' evolved to mean 'occurring at irregular intervals with separation'.
