Depends on your dialect of English, some Americans on the East Coast don't pronounce the "h" like we do on the West Coast (i.e. "human", "huge") - But there's also some "h" words we use with the sound of "an" like when we say:
It is an honor. An honest request.
Some words the h at the beginning is effectively silent. honor/honour and honest are some of those words. Since the word begins with a vowel sound the 'an' is used before it. For other words where the h is sounded, such as hat, then the a is used. So it depends on your dialect whether the h is sounded and thus whether the an or a is used. Of course the translation I did for this one is an enormous bear which sidesteps the whole issue.
When you are standing in front of an enormous bear you tend not to worry about such things a lot.
Whether you pronounce the "h" (hyooj) or not (yoog) it's still a consonant sound that requires "a". I've never heard anyone talk about "an huge (ooj)" anything.
In my opinion, it should be right. Though, without context showing that it is a male, you can't truly know. Also, a lot of people refer to most animals as an 'it.' Try reporting it though, it could be correct.
There might be a few in upper Italy, we have a handful in Austria and the dolomites seem like a nice place for them.
Why is: It is a big bear, not acceptable? Is there a better word In Italian for big?
Huge isn't a word I would use, large should be accepted in my opnion. I reported it.
I think it's slightly different and "gigante" would be a closer Italian version.
Adjectives that end in 'e' (grande, enorme, verde) don't change to match gender they only change to match singular or plural (ie for plural they becomes grandi, verdi)
Not all words change, for example singular grande is always just grande, and anyway it would never change to match orso, but it might change to match the gender of orso (la/il or un/una)
Usually the voices in Duolingo have bad acting, here the woman's acting was a bit more decent than usual.
The adjective (ie. enorme) has to be put after the noun in Italian - there are some exceptions but mostly the noun comes first.
