'enthusiastically-gathered' originates from the combination of 'enthusiastically' and 'gathered'. 'Enthusiastically' comes from the Greek word 'enthousiasmos', meaning 'inspired or possessed by a god', and 'gathered' is derived from the Old English 'gadrian', meaning 'to bring together'.

'enthousiasmos' transformed into the Latin 'enthusiasmus', and eventually became the modern English word 'enthusiastic'. 'Gadrian' evolved into the Middle English 'gaderen', and eventually became the modern English word 'gather'.

Initially, 'enthusiastically' meant 'inspired by divine influence', but over time it evolved into its current meaning of 'showing intense and eager enjoyment'. 'Gathered' has largely retained its original meaning of 'brought together'.
