"He is your son and he is happy, Samia."
Translation:هُوَّ ابْنِك وَهُوَّ سَعيد يا سامْية.
That's why I came here too, I will check it on the computer, but so far I use the app on my phone and somehow here I can't see the tips! So actually I would really appreciate to read here too the answer to this question, because this is the second time I meet this problem.
And I just checked now, so I reply to my own question here so that everyone could see it, because others might need it too: it depends on who we are talikng to: [a] sound at the end when we are talking to a masculine gender noun, and [i] sound when we talk to a feminine gender noun (i.e. not only people! It should be the same with e.g. "talking" ;) to a house vs. to a city)
