Side note... This family lesion section is intensely morbid! "My grandmother was sad when my grandfather died" ok. I get it. "My cousin died when she was ten"?!?! I'm almost scared to continue!
Should accept "umur dia"
"umurnya sepuluh" is good ... There is no need to have "tahun" at the end.
Its a perfect sentence
What does "umurnya" even mean? I have no idea.
Ya: her, his
Umurnya: Her/His age. In sentence usually, (s)he was ... years old
Why couldnt you use .. sepupuku
Hopefully Tini, Sri, Tono, Andi and Dimas families are still ok.
when u already use umurnya, then why u need to end with tahun after sepuluh? isnt it understood...
