I have noticed a difference in the pronunciation of the vowel [o] in the first syllabe of compleanno, compared to the last and also to the first in domani. I think that the three of them are unstressed, but in com it appears closer to the [u] in suo. Is there a reason for that? Am I hearing right? Could it be that compleanno being a composite word has two stressed syllabes?
(Sorry if this has been explained before.)
I agree. It seems that Duolingo has taught us that when in doubt of gender to always select male AND when the clue here is "il suo", why would I select "her" instead of "his"? Seriously, if anyone will please answer this question in a manner it is truly teaching us, please help.
