oscarra

oscarach, oscarra

bold, fierce, Irish oscar, champion; from the heroic name <Oscar>, son of <Oisian> (Irish Oisín, little deer or os, q.v.). Possibly <Oscar> stands for *ud-scaro-, "out-cutter", root scar of sgar, q.v. Zimmer derives it from Norse Ásgeirr, spear of the Anses or gods, and Oisian from the Saxon Óswine, friend of the Anses; which should give respectively Ásgar and Óisine, but the initial vowels are both o short in Oscar and Oisian. Doomsday Book has Osgar.
