As I expected. Actually, same in english; "strange" is anything that's weird or not ordinary; "stranger" is an unknown or foreign person. "Foreign" was later borrowed from the French and never returned.

We have the same word but in a different set of meanings: "stran" is foreign, alien; "stranac" is a foreigner, however "strange" in the sense of weird or unusual is "čudan" - from "čudo", miracle, which is more from the verb "čuditi se", to wonder (at seeing a miracle or unusual event), then "čudak" (a strange or weird guy) etc.
