@Per utramque cavernam: This has me confused. What stems do we consider on suffixation?... Previously I had no impediment in taking "-ulus" from some earlier "-elos", since I imagined "porculus" being "porc-ulus" (as "pork-" is the root). But, if we make its stem "porco-" then "-lus" seems obvious" (and I then agree, when it seems rational to diminish the noun in "porko-" and not the undefined root in "pork-"). But then what to make of this "-eus", apparently from some "-eyos" (again this "-e-"?)? Why "argenteum" and not "argentoeum"? If here the "-o-" is "removed" to insert "-eus", might not the "-o-" in "porko-" be removed to insert "-elos" ("pork-elos" > "porculus")? What "-e-" is this? We see it also in *h₁léwdʰ-eros (ἐλεύθερος, līber) and the Ancient Greek form is better to prove it. There are many Ancient Greek words apparently with this "-elos" ("-ελος"). Might it not be the Latin "-ulus"? -GuitarDudeness (talk) 15:18, 2 February 2018 (UTC)
