Like munia ("duties"), it is derived from Proto-Indo-European *(e)meyǝ- ("change, swap"). As is the case with such derivatives as "municipality", and "immunity", the concept of trading goods and services in a way that conforms to a society's laws is quite pertinent to this term. From the addition of the "co-" prefix came "communis" ("common, public"), which is cognate to the Old High German "gimeini", Old English "gemǣne", Old Dutch "gimēni" and Old Saxon "gimēni."
