"Ea este o fată."
Traducere:She is a girl.
No, both "este" and "e" mean "is".
The verb does not change with the gender of the subject, the second one is just a shorter way of saying the same thing. (All the other persons of this verb have a single form, not two.)
- he is = el este / el e
she is = ea este / ea e
it is = este / el este / ea este
In Romanian we do not have a pronoun for animals/objects, so depending on the context, we can either translate it with the feminine/masculine pronoun, or we can skip it and say just the verb.
I hope this is helpful.
