However, it's important to note that "Moldavia" can refer to a few different things:
* The historical region of Moldavia: This region is located in present-day Romania and Moldova. In this context, "Moldavias" would be used if referring to multiple historical regions with that name (which is unlikely).
* The country of Moldova: This is a sovereign state that is officially called the Republic of Moldova. In this context, "Moldovas" would be incorrect. You would simply use "Moldova" to refer to the country, even when talking about multiple countries.
So, while "Moldavias" is technically a grammatically correct plural, it's not commonly used and might be confusing in most contexts.
