'well-written' originates from the combination of 'well,' meaning 'in a good or satisfactory way,' and 'written,' the past participle of 'write,' which comes from Old English 'writan,' meaning 'to score, outline, draw the figure of.'

'written' changed from the Old English word 'writan' and eventually became the modern English word 'write.'

Initially, 'written' meant 'to score or draw,' but over time it evolved into its current meaning of 'to compose text.'
