Formal:
* သူငယ်ချင်း (thu nge chin) - This is the most common and formal way to say "friend".
Informal:
* မိတ်ဆွေ (meik swe) - This is a slightly more casual way to say "friend".
* အပေါင်းအသင်း (a pong a thin) - This refers to "friends" or "companions" in a group setting.
Close Friend:
* အချစ်ဆုံးသူငယ်ချင်း (a chit soun thu nge chin) - This means "best friend".
* ချစ်သူ (chit thu) - This literally means "lover" but can also be used to refer to a close friend.
It's important to note that:
* The way you address someone as a "friend" depends on your relationship with them and the situation.
* It's always best to err on the side of formality when speaking Burmese, especially if you're not sure of the appropriate level of closeness.
