Do you neew to repeat the subject? And is it compulsory in Romanian like in French or can you omit it like in Spanish?
All four are present tense.
a mânca (to eat)
a bea (to drink)
Later on, you'll learn about the past tense. Right now, though, we're just working on the present indicative. The past tense of mâncăm and bem would be am mâncat and am băut respectively, which are the same as the eu form.
