'advantageously-situated' originates from the combination of 'advantageous' and 'situated', where 'advantageous' comes from the Latin 'advantage' meaning 'benefit' and 'situated' from Latin 'situare' meaning 'to place'.

'advantageous' evolved from the Old French 'avantage' and 'situated' from the Latin 'situatus', eventually forming the modern English term 'advantageously-situated'.

Initially, it meant 'placed in a beneficial position', and this meaning has largely remained the same in modern usage.
