Birbhadra ji , Plz don't make a fooll out of ur self, when u don't know something its better to keep quiet, U know what " Something is better than nothing but remember nothing is better than nonsense". The word Shah came from the word persian, mean s king or saint. Thats how the word Badshah came , baad means great in pushto and theword shanshah also came from persian, sahan means highest place or the word throne. as far u r talking about gujrati shah , its different man, In Nepali there are two word "Sa", if u ask the persiaqn speaking people they will tell u what is the different. As far the nepalese Shah Dynasty goes their surname was" KHA" and one of the moghul emperor gave them the title shah.
