Attached Derived Quadrilateral - Bab 1: Tafa'lul & Bab 2: Tafa'lul & Bab 3: Tamaf'ul

1. A New Mulhaq Group

This level begins forms attached to a derived quadrilateral pattern, like تَدَحْرَجَ.
Here we study the first 3 examples in this section:
1. تَجَلْبَبَ.
2. تَقَلْنَسَ.
3. تَمَسْكَنَ.

2. Bab 1: Tajalbaba

Start from the earlier form جَلْبَبَ.
Bab 1 adds تَـ at the beginning:
جَلْبَبَ → تَجَلْبَبَ.
Its Masdar is تَجَلْبُبٌ, meaning to wear or put on a cloak/outer garment.

3. Bab 1: Taught Sarf Sequence

تَجَلْبَبَ يَتَجَلْبَبُ تَجَلْبُبًا فَهُوَ مُتَجَلْبِبٌ
Read the slots:
1. Active past: تَجَلْبَبَ.
2. Active Mudhaari': يَتَجَلْبَبُ.
3. Masdar: تَجَلْبُبٌ.
4. Ism Fa'il: مُتَجَلْبِبٌ.
The imperative explicitly used in this level is تَجَلْبَبْ.

4. Bab 2: Taqalnasa

Start from the earlier Mulhaq form قَلْنَسَ.
This form already contains an inserted نْ between the second and third root letters.
Bab 2 adds تَـ at the beginning:
قَلْنَسَ → تَقَلْنَسَ.
Its Masdar is تَقَلْنُسٌ, meaning to wear a cap.

5. Bab 2: Taught Sarf Sequence

تَقَلْنَسَ يَتَقَلْنَسُ تَقَلْنُسًا فَهُوَ مُتَقَلْنِسٌ
Read the slots:
1. Active past: تَقَلْنَسَ.
2. Active Mudhaari': يَتَقَلْنَسُ.
3. Masdar: تَقَلْنُسٌ.
4. Ism Fa'il: مُتَقَلْنِسٌ.
The prohibitive explicitly used in this level is لَا تَتَقَلْنَسْ.

6. Bab 3: Tamaskana

Bab 3 is represented by تَمَسْكَنَ, based on the triliteral root س، ك، ن.
Its main structural sign is that both تَ and مَ are added before the first root letter.
Its Masdar is تَمَسْكُنٌ, used here for adopting or displaying a state of humility, helplessness, or poverty.

7. Bab 3: Taught Sarf Sequence

تَمَسْكَنَ يَتَمَسْكَنُ تَمَسْكُنًا فَهُوَ مُتَمَسْكِنٌ
Read the slots:
1. Active past: تَمَسْكَنَ.
2. Active Mudhaari': يَتَمَسْكَنُ.
3. Masdar: تَمَسْكُنٌ.
4. Ism Fa'il: مُتَمَسْكِنٌ.
No additional command, prohibitive, passive, or Ism Maf'ool form is added here.

8. Compare the Three Patterns

The easiest way to distinguish the 3 patterns is to watch what is added.

Main added featureExampleBab
Initial ت added to جَلْبَبَتَجَلْبَبَ1
Initial ت added to قَلْنَسَتَقَلْنَسَ2
ت + م before the first root letterتَمَسْكَنَ3

All three paradigms in this level are taught primarily through active forms.
