It is not compulsory in the UK.
There aren't "last names for girls" and "last names for boys." Its just last names. For the first names there are names for different genders, but not for the last names. Some last names are: Zamora, Smith, Turner, Williams
College football, as a whole, doesn't decide on when to do anything. The institutions themselves decide whether or not to place names on the back of jerseys, and to this day, some teams have names and some do not.
i don't know try reading the names and take a guess
Though it is traditional in many Western societies it is not compulsory.
Something is compulsory if you have to do it, if you are forced to do it. If you have a choice, it's non-compulsory.
NothingSora, Kairi, and Riku do not have last names. --------------------------------------------------------------------------------------------------------------I would say that it is not that they don't have last names, it is that their last names are currently unknown.--------------------------------------------------------------------------------------------------------------I agree, but it is a possibility that they might not even have last names.
bryant
Any Spanish last names
Their last names are Subaku.
Their last names are not known, but their first names are Shanna and Stephanie
Neither Bert nor Ernie weren't given last names, so nobody knows what their last names are.
