Analyze the simple noun-khabar examples in this level in three steps.
1. Name the defective verb and understand its meaning.
2. Find the person or thing being described: its marfu ism.
3. Find the state or description: its mansub khabar.
Then check the sign of nasb: fathah in غَنِيًّا, but ya in مُنْصَرِفِينَ.
This method prevents two common mistakes: reversing ism and khabar, and looking only for fathah.
