* صباح الخير (Sabah al-khayr): This is the most common and formal way to say good morning in Arabic. It literally translates to "morning of goodness."
Informal:
* صباحك سعيد (Sabahuk sa'eed): This is a more informal way to say good morning and literally translates to "your morning is good."
* صباح النور (Sabah al-noor): This means "morning of light" and is considered slightly more poetic.
Note:
* In some dialects, you might hear variations like "صباح الفل" (Sabah al-fool) or "صباح الورد" (Sabah al-ward), meaning "morning of flowers." These are more playful and informal.
* It's always good to be aware of the context and the relationship you have with the person you're greeting.
Ultimately, the best way to greet someone is the way that feels most natural and comfortable for you.
