Usted is the same as the third person in Spanish. It is equivalent to el and ella

anonymous · Answer

Usted isn't exactly the same as el y ella. It can be used as a more general you without gender. You talk to me. Usted me habla. She talks to me. Ella me habla, etc.

It has different meaning - "you", correct. What I meant to say is that it is on the same level as el and ella in terms of 3rd person. I was unclear.
