"هَل جَدَّتَك خَلْفَك يا سيث؟"

Translation: Is your grandmother behind you, Seth?

[Christoph55835]

Should be جَدَّتُكَ

[lukas.tu]

But the grammar taught in the this course shows differently. like this one

[sartma]

Hovering over خلفك doesn't show the meaning...

[Is6Li3XB]

(ghalfaka) meaning is missing. please fix it. thanks

[tsuj1g1r1]

It's khalfaka though. And for what it's worth, it means "behind you (male, singular)."

[TheQaswarah]

Should accept Granny and Grandma as synonyms to Grandmother!!

[Yuri636Sam]

Behind you is خلفك
خلف is back or behind
And the ك is referring to you like possession or prepositioning like "your" behind or behind "you"
