'islander' originates from the word 'island,' which comes from Old English 'ī(e)gland,' where 'ī(e)g' meant 'island' and 'land' meant 'land.'

'ī(e)gland' transformed into the Middle English word 'iland,' and eventually became the modern English word 'island.'

Initially, it meant 'land surrounded by water,' and this meaning has largely remained the same in modern usage.
