These are also ghayr munsarif nouns:
- names: أُسَامَةُ، بَاكِسْتَانُ، عُمَرُ، عِمْرَانُ
- other forms: صَفْرَاءُ، غُرَبَاءُ، مَسَاجِدُ
In their basic form without al or idafah, each has one dammah in the nominative and one fathah in both accusative and genitive. The reasons that place these words in this class are a separate classification; do not guess a reason merely from meaning or spelling.
