The origin of the given name Árpád is much simpler than a “pet name“ based on the noun for barley. It is the name of the chief of the seven Hungarian tribes who conquered the Hungarian basin in the 10th century. Some of Bela Kalman's examples seem rather odd, but I think he was mainly studying names that occurred prior to the 16th century. I think there are better discussions of Hungarian name origins out there. I have heard that in later times, at least until fairly recently, given names were required by law to come from a list of those that were acceptable, most of them biblical and/or named for saints. Any truth here? Since name days are celebrated in Hungary rather than birthdays, I have sometimes wondered what happened with people who were given unusual names that would not show up among the name days. Janet
