What does deus mean?
'Deus' is the Latin word for 'god,' adopted directly into English without translation. In contemporary usage it almost never appears on its own; instead, English preserves it inside a handful of learned phrases inherited from classical and medieval scholarship. By far the best known is 'deus ex machina' — literally 'god from the machine' — which names the ancient Greek and Roman theatrical device of lowering a god onstage by crane to resolve an otherwise hopeless plot. Today the term criticizes any contrived, unearned solution to a story's problems. Other survivals include 'deus absconditus,' the hidden god of certain theological discussions. Because 'deus' derives ultimately from the same Indo-European root that produced 'divine,' 'deity,' 'Jupiter,' and even the name of the Greek god Zeus, it sits at the head of a remarkably wide family of words about divinity. Writers invoke it when they want a tone that is scholarly, classical, or faintly ironic, and its very Latinness is part of its effect: it signals learning rather than everyday speech.

Etymology of deus
'Deus' is the ordinary Latin noun for 'god,' going back through Proto-Italic to the Proto-Indo-European root *dyeu-, meaning to shine or the daylight sky, which also yielded the Greek Zeus and the Sanskrit deva. English borrowed the Latin word whole, largely through scholarly and ecclesiastical writing of the medieval and early modern periods, rather than developing it naturally from Old English. Its most prominent modern life is in the borrowed phrase 'deus ex machina,' taken from Greek dramatic practice but given its Latin form by Roman writers such as Horace.
