Does anybody know if and how following expressions denoting the "honeycomb" could be connected? I am lost.
 
There is a word in Czech, having the same meaning: "strdí". If we compared it to other Slavic expressions, we can get PS *strIdI/strIdU. It has been compared to MidNld ro:te, röte "honeycomb", Nld raat and G Ross(e), all < PG hruti < IE *k^rudi- ? Could it be like that?
 
Then, what about these:
 
Latin  "kerion"
Russian "korž"
French: "rayon"
