"Are you fine?"
Translation:क्या तुम ठीक हो?
Do you mean 'क्या'? So first of all क्या means 'what', or can also be a question marker when used like this at the beginning of the sentence. Also there is no क्यी, it is always क्या.
How do we know the word order? It is telling me to put "aap" before क्या and then when tum is used to put क्या first??? HELP!!! my brain is exploding. Also my teacher said you can put क्या at the start if any sentence to make it a question, but I get marked as wrong by duolingo for the word order
The rule of thumb is that you place क्या at the start of the sentence for yes/no questions (by which I mean the answer to the question can just be हाँ or नहीं ). These are basically statements that are turned into questions by prefixing them with 'क्या' and correspond to questions which use 'Do', 'Will', 'Are' etc in English.
Eg: क्या तुम अमेरिका से हो? (Are you from America?), क्या आपने खाना खाया? (Did you have food?)
You put क्या right before the verb if it is a question that cannot just be answered by a 'yes' or a 'no'. These are questions that use a 'What' in English. Eg: तुम क्या खाओगे? (What will you eat?) आप क्या बोल रहे थे? (What were you saying?)
