I was thinking about the words 'pronumeral' and 'pronoun',pronumeral and pronoun; I realisedrealized they both share a prefix, and are both proxies for numerals and nouns. I was wondering if there is any connection between the words, as 'proxy' since proxy also begins with 'pro'pro. If 'proxy'proxy is unrelated, is there any reason for the two words to start with 'pro'pro?
