'intermittently-noticed' originates from the combination of 'intermittently' and 'noticed', where 'intermittently' comes from Latin 'intermittere', meaning 'to leave off', and 'noticed' from Latin 'notitia', meaning 'a being known'.

'intermittently' changed from the Latin 'intermittere' to the Old French 'intermettre', and eventually became the modern English word 'intermittently'. 'Noticed' evolved from the Latin 'notitia' to the Old French 'noter', and eventually became the modern English word 'noticed'.

Initially, 'intermittently' meant 'to leave off or pause', and 'noticed' meant 'a being known'. Over time, they evolved into their current meanings of 'at irregular intervals' and 'observed or perceived', respectively.
