* بخير، شكراً (bikhair, shukran): "I'm fine, thank you." This is a polite and common response.
* الحمد لله (Alhamdulillah): "Praise be to God." This is a very common and pious response, expressing gratitude for good health.
* تمام (tamaam): "Fine" or "Okay." This is a more casual and shorter response.
* كويس (kwayis): "Good." Similar to "tamaam" in level of formality.
* منيح (meni7): "Good" (Levantine Arabic). This is a slightly more informal variant used in Levant region (Syria, Lebanon, Palestine, Jordan).
The best response will depend on context. If speaking to an elder, a more formal response like "بخير، شكراً" is preferred. If speaking to a peer or someone younger, "تمام" or "كويس" might be more appropriate.
