so I'm fine
I'm so good
estoy asi asi
Estoy BienEstoy mas o menosorEstoy asi-asi(Some people say that this is used more for when a person is ok, and does not want you to help them, they will say asi, asi, like saying, "It's okay, I can do it myself" But it does not indicate that they are ok, it is not used in a proper sentence, mostly for a situation where they do not need help and are saying not to help as an indicator that they are ok to do it themselves.)
bien=good, asi-asi=o.k., mal=bad
You start by not saying "Estoy asi, asi" in the first place. It means "I'm that way, that way". It's a mistake made by Spanish students. Assuming you want to say "I'm so-so." In Spanish you would say, "Estoy mas o menos" or "Estoy regular". "Asi" means "like that" or "that way". You could say, "Soy asi" meaning "I'm like that" or "I'm that way" referring to some character trait of yours. You could also say "Estoy asi" meaning, again, "I'm that way" but referring to how you are positioned or some condition you are in.
It depends on how you are feeling. Most of the time, a polite response would the same as in English. I'm well. Estoy bien. There are many other possible responses. If you are happy, "estoy feliz". If you are ill, you could say "Estoy infermo." If you are just mediocre, "más o menos" or "regular". Whatever your condition or mood is.
Como estas usted is asking "How are you?" in a formal manner. You could reply with:Yo estoy mal (I am feeling bad)Yo estoy asi asi (I am so so)Muy bien (Very good)There are many ways to reply. You just need to say "Yo estoy" (I am) and then a word describing your attitude or feeling.
Nothing :) It's a mixture of Spanish and French. Did you mean "moi asi?" That means "me too" in French. "asi asi" is Spanish for "so-so." "moi" is French for "me."
'How are you?' = 'Como esta usted/estas?' (accent on 'a'; formal/informal) 'Me siento bien/mal/asi-asi' = 'I feel well/bad/so-so'
Así = thus, thusly, like this, that's the way.
bien (good) or mal (bad) then say gracias y tu (thanks and you?)Como esta? is the polite enquiry 'How are you' or 'How is he/she?' (but only if there is an accent on the 'a' in esta'. If not, it means either 'Like this (woman, or feminine gender noun)' or 'I eat this (feminine noun object)').Assuming it is WITH the accent, you could respond:Bien, gracias (Well, thank you)Asi asi, gracias (So-so, thank you)(To respond negatively might require more-complicated language in response)
"Deje asi" means "let it be"
That's how we do it.
