Subclass of the broken plural, used for a number between 3 and 10.
There are four patterns for this plural:
1. أَفْعِلَة like أَلْسِنَة from لِسان “tongue”
2. أَفْعُل like أشْهُر from شَهْر “month” (as opposed to شهور which indicated a greater number)
3. فِعْلَة like فِتْيَة from فتى “youth, young man”
4. أَفْعَال like أَعْمَال from عَمَل “work”
