I am using an app to learn Italian, and it has been showing me sentences such as,
"Mio cugino fa l'avvocato."
I understand that this means, "my cousin is a lawyer," or, "my cousin works as a lawyer". However, I don't understand the difference between it and,
"Mio cugino è un avvocato."
Do these sentences mean exactly the same thing, or is there a subtle difference?
