Questions & Answers about حضرتك محتاج سكر في الشاي، ولا الشاي كده كويس؟
حضرتك is a polite way to say you in Egyptian Arabic. It literally comes from a word related to your presence, but in real life it functions as a respectful form of address.
It is very common in customer service, with strangers, older people, or anyone you want to speak to politely. A less polite or more neutral version would be إنت.
محتاج means needing / in need of. In Egyptian Arabic, words like this often act like everyday present-tense expressions, so حضرتك محتاج سكر means Do you need sugar?
It is very natural in this kind of situation. You could also hear عايز in other contexts, but محتاج fits well when asking whether someone needs something.
Yes. If you are speaking politely to a woman, you would usually say حضرتك محتاجة سكر في الشاي؟
Only محتاج / محتاجة changes here because it describes the person being addressed. Later in the sentence, كويس refers to الشاي, not to the person, so that part stays the same.
