Kayf al-aal? = How are you? (or Kayf aalak? to a man, Kayf aalik? to a woman)
Anaa bi-khayr, al-amdu li-Llah. = I am fine, praise God.
Wa anta/anti? = and you? (m/f)
Kayfa tashcur al-yawm? = How do you (m.) feel today?
You can answer this question with the sentence, "I feel....." Ashcur bi.... = I feel...(with noun)
But just like in English, it's easier in Arabic to answer with something like "I am hungry" than it is to say "I feel hunger." Many adjectives describing a physical state of being end with -aan. To make them feminine, as with other adjectives, you add -ah at the end.
