What does demonically mean?
"Demonically" is an adverb meaning in a manner characteristic of a demon — that is, with fiendish, malevolent, or supernatural wickedness. It is formed from the adjective "demonic," which traces back through Latin daemonium to Greek daimonion, originally referring to a spirit or divine power before acquiring its strongly negative sense in Christian tradition. In contemporary usage the word appears almost exclusively in figurative contexts: a character may grin, laugh, or glare demonically, a machine may roar demonically, and a task may seem demonically difficult. Its connotations are overwhelmingly negative when applied to people, suggesting cruelty or malice, though it can be used playfully or hyperbolically for intensity. Writers of fiction, especially horror and fantasy, favour it for vivid characterization. A rarer variant, "demoniacally," carries the same meaning but is seldom encountered outside formal or archaic prose.

'Demonic' entered English through Latin and Greek — but its cousin 'pandemonium' was coined by Milton as the capital of Hell, giving this word family a literary pedigree few adverbs can claim.

Etymology of demonically
"Demonically" derives from the adjective "demonic," formed from "demon" plus the suffix -ic, with the adverbial -ally added. The noun "demon" comes from Latin daemon, itself borrowed from Greek daimon, meaning a spirit or lesser deity; in Greek usage the word was morally neutral, but Christian tradition recast demons as evil spirits, giving the English word its malevolent force. The adverb emerged in English by the seventeenth century as religious and literary writing about spirits flourished.
