Is Carlos A nickname because growing up that was my nickname and is Carlos Alberto a first and last name ?

Carlos Alberto are christian names (FIRST AND MIDDLE NAME when you see them together)

But those names can be used separately too. Carlos Perez or Alberto Perez. (Perez is the last name)

Carlos Alberto isnt an particularly quickly ahead first and middle call used jointly, Carlos is amazingly quickly ahead tho. Carlos means "Charles" in English yet Carlitos might want to nicely be used as a nickname (Charlie xD) ... Karl Michel is Carlos Miguel in Spanish btw ... xD

Carlos is Spanish for Charles. Karl is another version of Charles. A nickname can be anything. People call me Duck. My ex-husband's name is Paul, but some people call him Pablo.

Carlos Alberto could be a first and middle name or a first and last name. There aren't a lot of rules with names. You can call yourself anything you like and name your kid almost anything. Some places won't allow you to give a kid a vulgar or obscene name.

i know what you mean,when i was growing up,i was called, little little kid,how times change.such is life,what can i say.
