Where it comes from
From Latin nūmen (“nod of the head; divine sway or will; divinity”) + -ous (suffix forming adjectives from nouns, denoting possession or presence of a quality). Nūmen is believed to derive either from Latin *nuō (“to nod”) or from Ancient Greek νοούμενον (nooúmenon, “influence perceptible by the mind but not the senses”) (ultimately from νόος (nóos, “mind; thought; purpose”)).
