2-categories and two categories

Actually I think there is an audible difference between the way native speakers of English (of whatever dialect) pronounce 2-categories and two categories, just as there is a subtle difference between the way the White House (the American presidential mansion), the white house (a residence of like color) and even the White house (where the White family reside) are pronounced. The phenomenon is called a "superfix" by linguists. (And once again, categorist in their idle moments show linguistics to be their favorite hobby.) Best Thoughts to all, David Yetter
