'wind-blown' is a compound of 'wind' and the past participle 'blown' (from 'blow'). 'wind' originates from Old English 'wind', meaning 'moving air'; 'blown' is from the past participle of Old English 'blāwan' (to blow).

'wind' comes from Old English 'wind' and retained its form into Modern English; 'blāwan' (Old English) became Middle English 'blowen' and produced the past participle 'blown', which combined with 'wind' to form the compound adjective 'wind-blown'.

Initially the components meant 'moving air' and 'to blow'; together they have long meant 'moved or affected by the wind', a meaning that has remained stable into modern usage.
