Formation and meaning
The sound masculine plural keeps the singular stem recognisable and adds a case-sensitive ending.
| Singular | Nominative plural | Accusative/genitive plural | Meaning |
|---|---|---|---|
| مُعَلِّمٌ | مُعَلِّمُونَ | مُعَلِّمِينَ | male/mixed teachers |
| مُهَنْدِسٌ | مُهَنْدِسُونَ | مُهَنْدِسِينَ | engineers |
| مُجْتَهِدٌ | مُجْتَهِدُونَ | مُجْتَهِدِينَ | hard-working people |
Sound means the stem remains substantially intact. It does not mean every masculine noun uses this plural.

Choose ـونَ or ـينَ from the noun’s job
Subject / nominative
حَضَرَ الْمُعَلِّمُونَ.
Object / accusative
رَأَيْتُ الْمُعَلِّمِينَ.
After preposition / genitive

Spelling alert: The nūn remains in ordinary use, but drops when the sound plural is the first term of an idāfa: مُعَلِّمُو الْمَدْرَسَةِ.
