"صَحيفة اَلْأُسْتاذ زَرْقاء."
Translation:The professor's newspaper is blue.
I wrote a similar comment elsewhere. "The newspaper of the professor is blue." is a better translation because it is not using the possessive form. Let us ask the question, What is blue? The newspaper is blue. Whose newspaper? Professor's. So? The newspaper of the professor is blue. Please have some English speaking personnel check alternative answers as well.
