A fellow member of a Latin Discord server I participate in posted this link to an article with a question regarding how one would interpret the phrase "solitō māiōre". Despite our efforts to interpret it, we couldn't come up with any meaningful literal(-ish) translation. Google (and other search engines) yielded no fruitful results either, with the only meaningful information gained being the knowledge that it was likely an epigram or idiom of some kind (which was often labeled with "Aus. Epigr. 56.3" in the results I could find).
What does this phrase, "solitō māiōre", mean?
