best way is to lissten to both sound, full spead and slow speed. She do an "ah-breath" between those words.
lol! Un, Ahhhhh.... yup got it. I was silly for thinking it was Una, when all along it was Un ahhhh :)
The individual sounds seem to be taken from some longer recording. In my experience, the Italian accent leaves the tongue very far forward - on the teeth- on certain word endings, in this case, "un." The result is a release of air while the mouth resets from "n.". When slowed down, this effect is exaggerated. Listening to "un" and "una" side by side, the difference is apparent, as the "-a" sounds much more deliberate. Seems to be just a sloppy editing job.
perfect analysis! I was comforted to see that others heard the same confusing sound.
To all those complaining that the slow version is incorrect: Italian is not spoken as in the slow version. Never. That's just a learning aid for you. So saying that it is unfair because it is pronounced in an odd way is like saying that it is unfair that Italian has a different grammar than [insert language here] :-)
So what is the plural of nouns that end with e? Would it just be leoni because it's masculine? Can animals be both feminine and masculine, depending on the animal's gender?
As a general rule, nouns and adjectives ending in -e in the singular end in -i in the plural, regardless of gender (il cane, i cani; l'arte, le arti; l'otre, gli otri; la parte, le parti); of course there are a few exceptions.
As for animals' gender, not all of them have a grammatical one matching their biological one; just like in English there is a male lion (leone) and a female lioness (leonessa), but only one word for tiger/tigress (tigre, feminine) regardless of its gender.
