'wonderfully' originates from the Old English word 'wundorlic,' where 'wundor' meant 'wonder' and '-lic' was an adverbial suffix.

'wundorlic' transformed into the Middle English word 'wonderful,' and eventually became the modern English word 'wonderfully.'

Initially, it meant 'full of wonder,' but over time it evolved into its current meaning of 'extremely good or pleasing.'
