'seaward' originates from Old English, specifically the word 'sǣweard,' where 'sǣ' meant 'sea' and 'weard' meant 'toward.'

'sǣweard' transformed into the Middle English word 'seaward,' and eventually became the modern English word 'seaward.'

Initially, it meant 'toward the sea,' and this meaning has largely remained the same in modern usage.
