'enthusiastically' originates from Greek, specifically the word 'enthousiasmos,' where 'en-' meant 'in' and 'theos' meant 'god.' 'Designed' comes from Latin, specifically the word 'designare,' where 'de-' meant 'out' and 'signare' meant 'to mark.'

'Enthousiasmos' transformed into the French word 'enthousiasme,' and eventually became the modern English word 'enthusiasm.' 'Designare' transformed into the French word 'designer,' and eventually became the modern English word 'design.'

Initially, 'enthusiastically' meant 'possessed by a god,' but over time it evolved into its current meaning of 'with great excitement or interest.' 'Designed' has largely retained its original meaning of 'to plan or create.'
