غيرُ is a noun which will create Idaafa when it is used with another noun (a). It  also serves to negate nouns and adjectives and may be translated "non-," "un-," and so on. When it is used in such a Syntactical Environment (i.e., with adjectives) it creates what we call "Phony/Fake Idaafa," where the second term is an adjective (b).
