When you think you've learned a word, all of a sudden there's a male and female version with the same meaning!
Haha, yes :D Same here :)
«Ele» is like «ei», but female form?..
Yep, exactly :)
Esti roman ?
Da eu sunt!!
That's kind of confusing, since ele is Portuguese for "he". I don't even study Portuguese much, but apparently enough to be confusing!
Do I have to use the term "om" when we refer to the human being in general?
Depends. Om is for both (= human), but also Ei could be used for a mixed group (Ei beau apa - group of boys or boys and girls)
