'brave-hearted' originates from Middle English, combining 'brave' from Old French 'brave' meaning 'courageous' and 'hearted' from Old English 'heorte' meaning 'heart'.

'brave-hearted' evolved from the Middle English term 'brave' and 'hearted', eventually forming the modern English compound adjective 'brave-hearted'.

Initially, it meant 'having a courageous heart', and this meaning has largely remained the same in modern usage.
