Yes it should be جارُك
When the sentence begins with a noun, it always ended by ( ُ ) and then the possessive prefix if there's one.
But in the dialect language we don't pronounce it. For exemple, here in Morocco, we pronounce it ( جارْك jarek )
Im confused too with the accents
It should be جارُكَ
Jaraka or jareka?!
Whats the difference
