Meaning & History
The first element of this archaic name is derived from Proto-Slavic rědъkъ "rare, sparse". Compare modern Russian redkij or redkiy, Croatian rijedak and Polish rzadki, all of which mean "rare, scarce, uncommon". The second element is derived from Slavic mir "peace", which gives the name the meaning of "peace is rare". Last but not least, it may be possible that in some cases, this name is a variant form of Radimir (see Radomir).
