"هَل أَنْتِ مَغْرِبِيّة فَرَنْسِيّة يا سامْية؟"
Translation:Are you French Moroccan, Samia?
No. Because "French" is being used as an adjective to describe what kind of Moroccan she is. In English, adjectives come before the nouns they modify so it's "French Moroccan" in English. In Arabic, adjectives come after the nouns they modify so it's "maghribiyya faransiyya" in Arabic.
