'island-raised' originates from English, specifically the words 'island' and 'raise', where 'island' meant 'land surrounded by water' and 'raise' meant 'to bring up.'

'island' comes from Old English 'ī(e)gland' and was later influenced in spelling by Old French 'isle'; 'raise' comes from Old Norse 'reisa' and Old English 'rǣran' (to rear), with the past participle forming modern 'raised'. The compound adjective formed in modern English by joining these elements.

Initially, the elements meant separately 'land surrounded by water' and 'to lift or rear'; over time they combined into the modern adjectival compound meaning 'brought up on an island.'
