'non-window-related' originates from Modern English, composed of the prefix 'non' (from Latin 'non', meaning 'not'), 'window' (from Old Norse 'vindauga', where 'vindr' meant 'wind' and 'auga' meant 'eye'), and 'related' (from Latin 'relatus', the past participle of 'referre', where 're-' meant 'back' and 'ferre' meant 'to carry').

'non' is inherited from Latin 'non'; 'window' changed from Old Norse 'vindauga' ('wind' + 'eye') into Old English and later modern English 'window'; 'related' comes via Latin 'relatus' and Old French/Middle English forms into modern 'related'. These elements were combined in modern English to form the compound 'non-window-related'.

The component elements originally meant 'not' (for 'non'), 'wind-eye' (for 'window'), and 'carried back/connected' (for 'related'); together in modern usage they have come to form the clear adjectival meaning 'not related to windows'.
