Enthusiasm originally meant inspiration or possession by a divine afflatus or by the presence of a god. Johnson's Dictionary, the first comprehensive dictionary of the English language, defines enthusiasm as "a vain belief of private revelation; a vain confidence of divine favour or communication. " In current English vernacular the word simply means intense enjoyment, interest, or approval.
