Do I sound natural and formal in these sentences? As in the birth certificate of my brother, Seyed Akbar, is said the word “Seyed” is added to the beginning of his name. So, in his documents he can be “Seyed Akbar Hosseini” or “ Akbar Hosseini”, based on the years, documents are produced or bank accounts are opened. The same thing is true for my father and the other brother, seyed adel.
