Although "Subha bakhair" is correct word-to-word legitimating translation, whereas generally there is no such greetings exist in Urdu speech, except "Shab-ba-Khair" for "Good night"

If someone just want to know how to formally greet morning or address somone with formal greetings in Urdu with exact common phrase, is "Aadab" or "Assalamuelekum" which still has been in common practice as first greeting commonly in homes.

Assalamuelekum, is in common practice in many schools, offices, work places as FIRST GREETING IN THE MORNING to each other. Otherwise, "Good Morning Miss/Sir" is also in common practice "as it is in English" in many Indo-Pak's private/gov. schools and offices. But "SUBHA KAHIR" never been heard or experienced in any school, work place or any private / government office. "Aadab" is also has been and still being in use as a common greetings by BBC World Urdu Radio Services since decades.

Thank you very much, I really appreciate for the support and efforts by whom, who do "agree" and who do not "agree" with my rendered answers. I do believe anyone's answer and opinion is respectful.

Certainly, everyone have right to "agree" or "disagree" by expressing their own point of view, and it should be left for the Asker to chose, or to decide, or to judge the most "appropriate" answer which they find most helpful to them. There is no point to push one "pro's" opinion to other who differ.

I will appreciate if my friends may kindly concentrate to support their proposed answers and avoid unnecessary debates.

Best Regards ..... Zack

"Adaab" is truer expression of "Good Morning" reflecting in Urdu culture. Although it can be translate word to word as "Subha Bakhair", but eventually it is never spoken commonly in Urdu speaking culture. "Good Morning" came from English culture, anyone who adopt this English manner, might say "Subha Bakhair", But in fact "Adaab" or "Assalamuelekum" is in common practice since decades. and still , whether Muslim or any other Urdu speaking society , commonly use "Adaab".
Even English Empire left their impression on Urdu.for example:the use of "salam saab" instead of "subh bakhair janab", when it is said to the superior's.whereas b/w equal level "adaab" or “adaab janab” is said among the Urdu speakers and otherwise "Good morning" is used as it is.
