Part of speech: noun

Definition: A word that names or refers to a person, place, thing, or idea. Nouns and personal pronouns are always substantives by nature. Other pronouns, numerals and most determiners readily function as substantives in English and many other languages. When present participles function as substantives in English, they are called gerunds; many other languages prefer to use infinitives more often for this purpose. Care in translation is needed when adjectives are used as substantives, because languages differ in which ones are permitted and which ones must remain adjectives.

Example sentence: The right of the people to a substantive part in the government of the Church is recognized and sanctioned by the apostles in almost every conceivable way.
