'vaguely-presented' originates from the combination of 'vaguely' and 'presented'. 'Vaguely' comes from the Latin word 'vagus', meaning 'wandering' or 'uncertain', and 'presented' is derived from the Latin 'praesentare', meaning 'to place before'.

'vaguely' evolved from the Latin 'vagus' through Old French 'vague', and 'presented' evolved from Latin 'praesentare' through Old French 'presenter'.

Initially, 'vaguely' meant 'wandering' or 'uncertain', and 'presented' meant 'to place before'. Over time, 'vaguely-presented' evolved to mean 'described or shown in an unclear manner'.
