Middle English prodigious English prodigious The adjective is derived from Late Middle English prodigious (“warning of disaster, portentous”), from Latin prōdigiōsus (“strange, unnatural; marvellous, wonderful, prodigious”), from prōdigium (“prophetic sign, omen, portent; prodigy, wonder”) + -ōsus (suffix meaning ‘full of’ forming adjectives from nouns). Prōdigium is derived from prō- (prefix denoting a forward direction, something before or prior, or prominence) + aiō (“to say, speak”) (ultimately from Proto-Indo-European *h₁eǵ- (“to say”)) + -ium (suffix forming abstract nouns). The English word is analysable as prodigy + -ous. The adverb is derived from the adjective.
