Entusiasmo: when inspiration had a god within

When Italians speak of entusiasmo for a project, they usually mean involvement, joy or eagerness to get started. Treccani records precisely these everyday uses of the Italian word. The discovery is that its history begins with a much less ordinary image: a person feeling filled by a divine force. The current meaning and the ancient one belong to the same history, but they are not interchangeable. [1]

The documented etymological chain leads from Greek enthousiasmós to the verb enthousiázō, to be inspired, and the adjective éntheos. That adjective combines en, within, and theós, god. This is therefore more than a chance resemblance between modern sounds: dictionaries trace connected Greek words. Il Nuovo De Mauro dates the Italian word to 1543–49; a dictionary’s dating does not, however, credit somebody with inventing the emotion itself. [2][1]

In ancient Greek culture this kind of inspiration concerned, among others, poets and people delivering religious pronouncements. Treccani’s encyclopedia recalls the question discussed by Plato: an inspired poet does not necessarily possess a rational explanation of what they say. The term later travelled through philosophical and religious debates, including Shaftesbury’s reassessment in his 1708 letter on enthusiasm. This is historical context, rather than a discovery announced in our own century. [3]

An example invented by our editors: a girl suggests building a cardboard town and persuades two friends to collect boxes. Saying that she works con entusiasmo aptly describes her involvement. There is no need to imagine a deity handing her the plans. If the cardboard bridge then collapses, the feeling does not become false: her eagerness to build was sincere, while the bridge’s strength was never guaranteed by it. [1]

A second editorial example: two people look at the same drawing. One immediately exclaims that it is wonderful; the other starts looking for materials and time to make it. We could use entusiasmo for both, although their actions differ. De Mauro includes intense admiration as well as dedication to a person or an ideal. Our scene explores those shades of meaning; it is neither testimony nor a psychological experiment. [2]

The important limit is that knowing a word’s origin does not require using it only in its oldest sense. In our editorial reading, the distance between divine inspiration and everyday involvement instead prompts a question about context: what does the speaker mean here? This English page also tells the story of the Italian word entusiasmo. It does not automatically assign the Italian word’s dating to English enthusiasm or offer a competing origin legend. [1][2]
