Trilateral Bare Irregular - Bab 3: Kada Yakadu & Weak Roots

1. Shadh Bab 3: Kada Yakadu

The third and final Shadh door in this section is كَادَ يَكَادُ.
The underlying pattern taught here is فَعُلَ يَفْعَلُ.
Its verbal nouns are الكَوْدُ and الكَيْدُوْدَةُ, with the sense of intending or being close to doing something.

2. Why the Surface Form Looks Different

This is a weak-middle verb: the second root letter is و.
Because the middle root is weak, the written forms do not look exactly like a sound-root example of the same underlying pattern.
The lesson highlights this exception with forms such as كُدْتَّ and تَكَادُ.
So learn two things separately: the underlying Bab pattern, and the actual surface forms used by this weak verb.

3. Active and Passive Forms

Read the first half of the Sarf-e-Sagheer as two blocks.
1. Active: كَادَ يَكَادُ كَوْدًا وَكَيْدُوْدَةً فَهُوَ كَائِدٌ.
2. Passive: كُوْدَ يُكَادُ كَوْدًا وَكَيْدُوْدَةً فَهُوَ مَكُوْدٌ.
This gives the active and passive verbs together with Ism Fa'il and Ism Maf'ool.

4. Active and Passive Side by Side

Compare the same grammatical slot in the two voices.

كُوْدَكَادَPast
يُكَادُيَكَادُMudhaari'
مَكُوْدٌكَائِدٌParticiple

The root remains the same; the form tells you whether the construction is active or passive.

5. Command and Prohibition

The weak middle produces very short command forms.

FormCategory
كَدْImperative
لَا تَكَدْProhibitive

These should be memorized as the displayed forms for this weak verb.

6. Dharf and Instrument Forms

The lesson then gives the place/time noun and three instrument forms.

FormCategory
مَكَادٌIsm Dharf
مِكَادٌIsm Aalah
مِكَادَةٌIsm Aalah
مِكْوَادٌIsm Aalah

The key distinction is the opening vowel: مَكَادٌ is Dharf, while the instrument forms begin with مِـ.

7. A Simple Map of the Level

Remember these points:
1. Shadh Bab 3 is كَادَ يَكَادُ.
2. The underlying pattern taught here is فَعُلَ يَفْعَلُ, but the weak middle changes the surface forms.
3. The Masadir are الكَوْدُ and الكَيْدُوْدَةُ.
4. Active/passive pairs include كَادَ / كُوْدَ and يَكَادُ / يُكَادُ.
5. Command/prohibition are كَدْ / لَا تَكَدْ.
6. The source-supported derived forms here end with Dharf and instrument forms; no later slots are added in this level.
