"I am fine."
You're not correct, because you have to use the irregular verb "aller" for this sentence, and no other verb. Je vais bien/ça va (verb: aller)
"Je suis bien"= means another thing, it's I feel comfortable when you are in your new sofa for instance, but it's not related to your health or moral, and can't be a reply.
Je suis en forme, yes, but it's more specific. The expected answer for "Comment vas-tu?" is Je vais bien/ ça va, etc... You can reply with "je suis en forme", but it's a bit weird because it's unusual. Greetings are usually not so specific, and the forms are always the same.
In case it helps you remember:
"D'accord" literally means "of/in accord". We have (borrowed) the same word and expression in English: an accord is an agreement. You might have heard, "Then we have (an) accord (an agreement)," or, "We are in accord (agreement)," in movies.
So you can't use it to mean "okay" (a really, terribly vague English word, though convenient) in any old sentence. You can only use "d'accord" where "Got it (I understand)" or "(Yes,) I agree" are appropriate.
No, you can't say "je suis bonne", (first, it's sexual, and second, you can't say it because it's not the good words)
You have to use the verb "aller" in French to mean that, not "to be" in this context. Je vais bien/ Comment ça va?/ ça va?/ ça va!
You have to use the adverb "bien" and not the adjective "bon/bonne". Je vais bien.
I had no idea, I would also have thought it would mean more about a person's personal goodness. Can you explain any further what a person is implying sexually by saying "je suis bonne"? Is it like saying "I am sexually interested right now" or like "I'm a great sexual partner" or...?
Try holding a letter, say "e." A dropdown menu of accented versions should appear. Make your selection without lifting your finger off.
If not, find the tools to choose accented letters option on key to left of Space bar. It has a cog wheel on it. Cog indicates tools. Another option adds a microphone. Gives speech to text. Very handy for English .. when it gets it right!
I was exploring a different answer "je suis bien" and it was marked correct! I am just wondering, if this "je suis bien" consider an acceptable or one of the common answers to "comment allez vous?".... and whether it is a formal or informal answer... does it "je suis bien" have an added or different meaning from "je vais bien" or "Ça va bien"
