'well-performed' originates from the combination of 'well,' meaning 'in a good or satisfactory way,' and 'perform,' from Old French 'parfornir,' meaning 'to carry out, finish, or accomplish.'

'perform' changed from the Old French word 'parfornir' and eventually became the modern English word 'perform.'

Initially, 'perform' meant 'to carry out or finish,' but over time it evolved to include the idea of executing with skill, as in 'well-performed.'
