Formal:
* آقای (Aghaye): This is the most common and formal way to address a man. It literally means "Mr."
* جناب (Jenab): This is another formal term, similar to "Sir" in English.
Informal:
* آقا (Agha): This is a more informal way to address a man, similar to "mister" or "sir" in English.
* جناب (Jenab): In some informal settings, Jenab can also be used as an informal address, but it's less common than Agha.
Example:
* آقای احمدی (Aghaye Ahmadi): Mr. Ahmadi (formal)
* آقا (Agha): Mister (informal)
It's important to note that the choice of address will depend on the level of formality and your relationship with the person you are addressing.
