Formal:
* শুভ সকাল (Shubho Sokal) - This is the most formal and respectful way to greet someone in the morning.
Informal:
* সকাল ভালো (Sokal valo) - This is a more casual and friendly way to greet someone.
* ভোর ভালো (Bhor valo) - This is another informal greeting, often used among friends and family.
You can also add "আপনাকে" (apnake) to the beginning of any of these phrases to make them even more polite:
* আপনাকে শুভ সকাল (Apnake Shubho Sokal) - This is a very polite way to say "good morning" to someone you respect.
* আপনাকে সকাল ভালো (Apnake Sokal valo) - This is a more casual way to say "good morning" to someone you know well.
Choosing the right greeting depends on the context and your relationship with the person you're greeting.
