Burma

The term refers to the historical and former official name of the nation now known as Myanmar. While the name change occurred officially in 1989, "Burma" remains in common usage in many Western diplomatic and academic circles, often to signal a lack of recognition for the military government that implemented the name change.

As a proper noun referring to a specific sovereign entity, it is used exclusively in the singular. It does not function as a common noun and therefore does not have a plural form.
