usted is the formal "you" and is conjugated the same way as el/ella. so they are the same verb. the informal you "tu"(accent over u) would be vuelves. it all depends on whom you are calling you. traditionally "Tu" is used with close friends, family, and people that are younger than you. usted used when speaking to authority, someone older than you, or someone ou might not know so well.
I don't think you are looking too deep, but you are making weird assumptions that will really hinder your language learning.
A word having multiple meanings in one language does not mean the analogous word in another language for one meaning will have all of those other meanings in the second language. There is not even a guarantee you will be able to find a word in another language that has a certain meaning. Extreme example is some language don't have a word for certain colours. There is not a perfect one to one relationship.
That would make sense when you think about it like irse means leave, unfortunately volverse means to become/to turn into/to get. Me vuelvo rojo en el sol.-I get red in the sun. Te vuelves loco- You go out of your mind.
Oh also, to return (something) actually has its own verb- devolver.
I was under the impression that vuelve meant "turn" rather than "return". I know volver is "to turn", therefore, why is ella revuelve incorrect? (I had forgotten the verb regresar. I think that would be more appropriate and that revolver may mean more "rotate" than "return", so I am not certain that revuelve fits. Yet vuelve seems off also.)
I was sitting there, selling turnips on a flatbed truck, crunching on a porkrine when she pulled up, she had to be thinking this is where rednecks come from. She had Hollywood written on her license plate, she was lost and looking for the interstate, needing directions, and I was the man for the job. I told her way up yonder past the caution light theres a little country store with an old coke sign, you gotta stop and ask miss bell for some of her sweet tea. Then a left will take you to the interstate, but a right, will bring you right back here to me. I was sitting there, thinking bout her pretty face, kicking myself for not catching her name, I threw my hat and thought you fool, it could've been love. Well, I knew my old ford couldn't run her down, she prolly didn't like me anyhow, so I watched her disappear into a cloud of dust. I told her way up yonder past the caution light, there's a little country store with an old coke sign, you gotta stop and ask miss bell for some of here sweet tea. Then a left will take you to the interstate, but a right, will bring you right back here to me. Is this georgia heat playing tricks on me or am I really seeing what I think I see the woman of my dreams coming back to me hee ee. She went way up yonder past the caution light, dunno why but something felt right, when she stopped and asked miss bell for some of her sweet tea, well mamma gave her a big ole' glass and sent her right back here to me. Thank God for good directions, and turnip greens. For some reason it didn't take this, and I really don't know why. Can I get an explanation?
