Did you realize this guy's name is an early Reconquista noble title ~ in gaelic ~ so he's either descended from Cornish knights, or Bretons ~ a "sa" is the fellow who held the flag on one end or the other of a line of mounted knights so they could make an orderly advance into the enemy's lies. "la" is pretty much an article as in "of the", and "Zar" would have to do with "castle" or "strong point" ~ and although "zar" is originally an Arabic term, it's fully infiltrated into Spanish.
Cornish knights
Cornish Game Hens is more like it....
