Pronouns, per Merriam-Webster, are “words in a language that are used as substitutes for nouns or noun phrases”. But it also seems that pronoun might mean supportive of (pro) a noun as opposed to against (con) a noun. Connoun would make a good word of the day…if it were, in fact, a word…or maybe, anyway. Likewise, antinoun could be a reasonable antonym for pronoun. Pronoun also could be interpreted as a professional (pro) noun. With all of these possibilities, it seems rather limiting for a pronoun to have to settle for being a mere substitute or sub (lesser) noun.
