Formal:
* صبح بخیر (Sobh be kheir): This is the most common and formal way to say "good morning." It literally translates to "Good morning."
Informal:
* صبح شما بخیر (Sobh-e shoma be kheir): This is a slightly more polite way to say "good morning" and translates to "Good morning to you."
* صبح به خیر (Sobh be kheir): This is a more casual way to say "good morning" and is often used between friends or family.
Note: It's important to use the correct form depending on the context and who you are talking to. For example, you would use "صبح بخیر" when talking to a teacher or a stranger, but "صبح شما بخیر" when talking to a friend or family member.
