To show or express enthusiasm; to speak or act with eager excitement and approval.
Back-formation from enthusiasm (Greek en- 'in' plus theos 'god' plus -iasm, originally meaning divine inspiration). Created in the 19th century by removing the -iasm suffix.
Enthuse is a relatively young word—it didn't exist until the 1800s when English speakers essentially 'reversed' the word enthusiasm, working backward to create a verb form that didn't previously exist.
