Is "româneşte" acceptable in place of "limba romana"? I've been to Romania a few times now and have always used, and learned to say, "vorbesc puţin româneşte", an no one has corrected me. However, if "vorbesc puţin limba romana" is the correct way to say it, I'd like to know for future reference.
Yes. According to the Romanian DEX, see link above, "româneşte" = "în limba română." Other than Sonkadonka's claim from above, I have never heard anyone to claim that "vorbesc româneşte" would be wrong and I have lived and studied in Romania for more than few months and had the privilege to speak with quite a few Romanians from different parts of the country... BTW, if you check above, you will find a reference to a very educational YouTube clip regarding your question!
