The word 'vaguely' originates from Latin, specifically the word 'vagus,' meaning 'wandering' or 'indeterminate.' 'Confirmed' comes from Latin 'confirmare,' where 'con-' meant 'together' and 'firmare' meant 'to strengthen.'

'Vague' evolved from the Old French 'vague,' and 'confirm' from the Old French 'confirmer,' eventually becoming the modern English words 'vague' and 'confirm.'

Initially, 'vague' meant 'wandering' or 'indeterminate,' and 'confirm' meant 'to strengthen together.' Over time, 'vaguely-confirmed' evolved to describe something not clearly or fully confirmed.
