Politely: "Hai, genki desu. Anata wa?"
Casually: "Genki dayo! Anata wa?"
genki desu ka or ikaga desu ka
Genki desu. Anata WA genki desu ka? I am well. How are you?
O genki desu ka→How are you? watashiwa o genki desu is wrong. When you describe yourself,do not use [o]. watashi WA genki desu→I'm fine. anata wadaijoubo desuka? is wrong.daijoubo is daijoubu. anata WA daijoubu desuka?→Are you well?
Genki Desu Ka? is how you say it.
I think you mean "genki desu ka". The correct way of spelling it in English would be "ogenki desu ka". It is Japanese for "How are you?" One would usually answer by saying "Genki desu. Anata wa?' which means "I'm fine, and you?"
You may say 'konnichiwa. genki desu ka,' written: こんにちは。元気ですか
This can generally be translated as: (by line) O genki desu ka? How are you? Watashi ha genki desu. I am well. Anata ha daijoubu desu ka? Are you all right?
kumusta (how are you) = お元気ですか? (o genki desu ka)
Watashiwa o genki desu means "I am fine" or "I am well"HoweverWhen speaking about yourself and your own condition, it would be improper to say o-genki (the 'o' here is a form of honorific).It would be much more natural to saywatashi WA genki desu.or simply genki desu.
if someone asked you "ogenki desu ka" (how are you) you can answer him by saying "genki desu" (i'm fine)
o genki desu ka? (oh ge (as in get) n-key de (as in desk) s ka (as in car)
Polite : 'O genki desu ka ano kata wa?' Casual : 'Genki na no ka aitsu?' or 'Dou shiteru kare wa?'
