Meaning & History
There are two possible explanations for the meaning of the first element of this name. The first explanation is that it is derived from Proto-Slavic měšati "to mix, to stir" (compare Croatian miješati, Slovak miešať and modern Polish mącić and mieszać, all of which mean "to mix, to stir"). The other explanation is that it is derived from Proto-Slavic mǫčiti "to torture, to torment" and Proto-Slavic mǫka "torture, torment", via Polish męka "torture, torment". Also compare the modern Polish verbs męczyć "to torture, to torment", ciemiężyć "to oppress" and uciemiężać "to oppress, to burden". Finally, the second element of this name is derived from Slavic mir "peace". As such, one could say that this name means something along the lines of "he who oppresses peace".
