Forms

ἐνθουσιαστικός (enthousiastikós), feminine ἐνθουσιαστική, neuter ἐνθουσιαστικόν; comparative ἐνθουσιαστικώτερος, superlative ἐνθουσιαστικώτατος; adverb ἐνθουσιαστικῶς.[1][2]

Etymology

It is from Ancient Greek ἐνθουσιάζω (enthousiázō, “to be possessed by a god”).[3] That verb is formed from ἔνθους (énthous), a contracted form of ἔνθεος (éntheos, “possessed by a god”), with the verb suffix -ιάζω (-iázō), and Wiktionary suggests that οὐσία (ousía) influenced its shape.[4][5]

Earliest recorded meaning

Plato uses it first, of a prophetic, divinely inspired nature in the Timaeus, and in the Phaedrus has the neuter as a noun for a state of inspiration.[1][5][6]

Semantic evolution

Plato and Aristotle use the word in two directions.[1] Passively it describes someone inspired or filled with a god, and Aristotle applies it especially to souls carried away by music.[1][5] Actively it describes what produces such rapture: certain melodies and harmonies in Aristotle's Politics, and mental illnesses joined with madness in the Problemata.[1][5] Strabo uses it of the ecstatic cults of the Cabiri and the Corybantes, Plutarch speaks of an inspired, initiatory wisdom, and Iamblichus of ecstasy produced by inspiration.[2][1]

Modern Greek took the word over as a learned form, Modern Greek ενθουσιαστικός (enthousiastikós), which now means rousing or expressing enthusiasm, as in an enthusiastic song or enthusiastic comments.[7][8]
