I am aware that sentences are sometimes made to show specific aspects of a language. However, I can not imagine ever saying, "Her onion is hot." "That onion," makes more sense as the sentence is about an onion. "Her dress is pretty," is, perhaps, a better illustration of the possessive.
My question, if I really have one, is just that. Am I learning Romanian with an awkward phrasing, or is this really no issue?
