'sandbank' originates from Old English, specifically the words 'sand' and 'banc,' where 'sand' meant 'sand' and 'banc' meant 'bank or ridge.'

'sand' and 'banc' combined in Old English to form 'sandbanc,' which eventually became the modern English word 'sandbank.'

Initially, it meant 'a bank of sand,' and this meaning has largely remained the same in modern usage.
