Etymology
'demoniac' originates from Late Latin 'demoniacus', from Greek 'daimon-' / 'daimonios' meaning 'of a spirit or demon'.
'demoniac' developed from Greek 'daimon' (δαίμων) → Late Latin 'demoniacus' → Middle English 'demoniak' / 'demoniac', eventually becoming the modern English word 'demoniac'.
Initially, it meant 'pertaining to a demon' or 'possessed by a demon'; over time it also acquired figurative senses of 'frenzied' or 'extremely wicked' used in modern English.
