I want to know the answer to the following question:
What does it mean to have the letters OU added to the ending of a males last name ?
All the background I'm provided with is that "Although surnames in mainland Greece are static today, dynamic and changing patronymic usage survives in middle names where the genitive of father's first name is commonly the middle name (this usage having been passed on to the Russians).". Is that enough to answer the question?
Answer: no
