نَصَرَ — يَنْصُرُ — نَصْرًا
He helped — he helps — helping/support.
This class is فَعَلَ يَفْعُلُ. The second radical takes fatḥah in the perfect and ḍammah in the imperfect: naṣara / yanṣuru.
Further verbs following the same pairing include دَخَلَ يَدْخُلُ (enter) and تَرَكَ يَتْرُكُ (leave).
The radicals remain the same; the distinguishing feature is the vowel pairing, not the introduction of a new root.
