'peacefully-built' originates from the English word 'peaceful,' which comes from the Old French word 'paisible,' meaning 'peaceful,' and 'built,' from the Old English 'byldan,' meaning 'to construct.'

'peaceful' evolved from the Old French 'paisible' and 'built' from the Old English 'byldan,' eventually forming the modern English term 'peacefully-built.'

Initially, 'peaceful' meant 'full of peace,' and 'built' meant 'constructed.' Together, they evolved to describe something constructed in a peaceful manner.
