Spanish help?

¿Cómo estás tú?

I know that it means: "How are you?"

My question is, is the "tú" neccessary?

Wheneer I've spoken to or greated someone or they've greeted me in Spanish, I"ve never heard the "tu" on it, they/I would just say Cómo estás

The tu is not necessary. In fact, I’ve never heard anyone use it either

@Jenny1234 I wonder why it's being included in the duolingo Spanish lesson🤔. All it's explaining is that tu is informal and usted is formal .

@iamnikki my guess is it’s just a reinforcement to beginners that you use estas when referring to “Tu”.

I’m also curious as to whether it could be a part of the dialect from Spain. I haven’t been on the Duolingo app in a couple of years so I don’t remember which dialect of Spanish they use

@iamnikki ok I reread your comment. I think they’re teaching the beginners the way to get used to understanding the difference between formal and informal: Como esta usted v como estas tu.

Although, as per my earlier comment, it could still be part of a dialect
