That's basically what I was going to point out. I don't know any Carlitas but I know a boy named
Carlos, that we sometimes call
Carlito.
He loves that. -ita/-ito is a Spanish diminutive, indicating "little". My aunt's name is
Marita because her mother's name is
Mary.
I really like Carlita though. I adore
Lolita, but people consider it unusable because of the book, which I don't understand, because it's simply a regularly used Spanish diminutive of
Lola.
