Ciao a tutti!
I have a question. I know that “to stop doing something” is smettere di fare qualcosa. Nevertheless I’ve heard Italian speakers add the pronoun la when using the verb in the imperative mood. So instead of
Smetti di fare questo!
I hear instead
Smettila di fare questo!
Is there a reason why the la should be there? It doesn’t seem to be doing anything. And why is it feminine (la) rather than masculine (lo)?
Grazie in anticipo!
