She can talk fairly normally, since she's practised at the language, but it is true that the language is very primitive, and it tends to be extremely inadequate for portraying inner, unobservable traits and qualities--then again, most Tralgs don't really believe too much in inner traits, since those can't be seen. So if you told a Tralg that there was an animal that had feathers and lived in a nest and laid eggs but then it got sick and now it has membranous wings and compound eyes and an hard shell, and then you asked the Tralg if it was a bird or an insect, the Tralg would be likely to tell you that it is now an insect.
