Earlier in my studies of Historical Linguistics and Classical Latin I hypothesized of Common-Slavic *muži "man" (alongside with Lithuanian žmuo, Latin homo, -inis, Old-English guma) to have descended from PIE root for "earth" *dhegh'- in the form of *dhgh'-m-ón "earthling" contradicting the contemporary explanation reasoning that the Common Slavic word was a borrowing from Germanic *man- but failing to explain the /ž/ element in it /ref. Machek: Slovak and Czech Etymological Dictionary, 1975/.
Now, I wonder what the modern PIE etymology has to say about this, whether it's been resolved for good in the meantime, and what is the current state of affairs. Was I right back then?
