Note: You need to understand this concept of verb classification before diving into pronoun-based verb conjugation. Read this: Ultimate Guide to Arabic Verbs: Fi'il Mujarrad vs Fi'il Mazid Explained

Arabic words are built using systemized patterns. Today we will study the fi'l tsulatsi mujarrad (فِعْلٌ ثُلَاثِيٌّ مُجَرَّدٌ) pattern in its entirety, covering all six chapters.

Read and comprehend the patterns and the verb examples. Once you master these 6 core patterns, unlocking hundreds of verbs becomes easy.

1. The Building Blocks: Wazan and Mauzun

Before looking at the 6 chapters/groups, let's understand how Arabic verbs are built.

• Wazan (وَزْنٌ - Template / Pattern): This is the master formula. In Arabic morphology (Sharaf - صَرْفٌ), we use the core root letters ف - ع - ل (Fa - 'Ain - Lam) as our universal template.
• Mauzun (مَوْزُوْنٌ - The Weighted Word / Example Verbs): These are the actual, real-world verbs that fit into the template.

Examples of Wazan and Mauzun

When we map a three-letter root verb to the master template, each letter of the verb corresponds to a specific position in the formula:

1. The Verb كَتَبَ (Kataba - To Write)

• ك (Kaf) is the فَاءُ الكَلِمَةِ (Fa' al-Kalimah - The First Radical / Fa position).
• ت (Ta) is the عَيْنُ الكَلِمَةِ ('Ain al-Kalimah - The Second Radical / 'Ain position).
• ب (Ba) is the لَامُ الكَلِمَةِ (Lam al-Kalimah - The Third Radical / Lam position).

2. Additional Examples

Here are a few more examples to show how this pattern works across different verbs:

• فَتَحَ (Fataha - To Open)
  • ف (Fa) is the فَاءُ الكَلِمَةِ (Fa' al-Kalimah / First Radical).
  • ت (Ta) is the عَيْنُ الكَلِمَةِ ('Ain al-Kalimah / Second Radical).
  • ح (Ha) is the لَامُ الكَلِمَةِ (Lam al-Kalimah / Third Radical).
• جَلَسَ (Jalasa - To Sit)
  • ج (Jeem) is the فَاءُ الكَلِمَةِ (Fa' al-Kalimah / First Radical).
  • ل (Lam) is the عَيْنُ الكَلِمَةِ ('Ain al-Kalimah / Second Radical).
  • س (Seen) is the لَامُ الكَلِمَةِ (Lam al-Kalimah / Third Radical).
• سَمِعَ (Sami'a - To Hear)
  • س (Seen) is the فَاءُ الكَلِمَةِ (Fa' al-Kalimah / First Radical).
  • م (Meem) is the عَيْنُ الكَلِمَةِ ('Ain al-Kalimah / Second Radical).
  • ع ('Ain) is the لَامُ الكَلِمَةِ (Lam al-Kalimah / Third Radical).

Note: This classification remains constant regardless of the vowel marks (Harakat - حَرَكَاتٌ) on the letters. For example, in سَمِعَ, the letter م is still the عَيْنُ الكَلِمَةِ even though it carries a Kasrah (كَسْرَةٌ - "i" sound) instead of a Fathah (فَتْحَةٌ - "a" sound).

2. The Verb Formula

Every regular verb has two main tenses you must learn together:

1. Fi'il Madhi (فِعْلٌ مَاضٍ - Past Tense Verb)
2. Fi'il Mudhari' (فِعْلٌ مُضَارِعٌ - Present Tense Verb)

In the Fi'il Madhi, the first and last letters always take a Fathah (“a” sound). The mystery is always the middle letter, called the 'Ain al-kalimah (عَيْنُ الكلمة). Look at how the vowel on that middle letter shifts when moving from the Past to the Present tense!

3. The Six Bab (Chapters) of Tsulatsi Mujarrad Verb Conjugation

Here is the complete breakdown of the 6 chapters. We will track how the vowel of the middle letter changes.

Bab 1: Fathah → Dhommah (فَتْحٌ - ضَمٌّ)

The middle letter (‘ain al-kalimah) has an "a" sound in the past (fi’l madi), and changes to a "u" sound in the present (fi’l mudari’).

• Wazan (Pattern): فَعَلَ — يَفْعُلُ (Fa'ala — Yaf'ulu)
• Mauzun (Examples):
  • كَتَبَ — يَكْتُبُ (Kataba — Yaktubu) — To write
  • نَصَرَ — يَنْصُرُ (Nasara — Yansuru) — To help

Bab 2: Fathah → Kasrah (فَتْحٌ - كَسْرٌ)

The middle letter has an "a" sound in the past, and changes to an "i" sound in the present.

• Wazan (Pattern): فَعَلَ — يَفْعِلُ (Fa'ala — Yaf'ilu)
• Mauzun (Examples):
  • ضَرَبَ — يَضْرِبُ (Dharaba — Yadhribu) — To hit
  • جَلَسَ — يَجْلِسُ (Jalasa — Yajlisu) — To sit

Bab 3: Fathah → Fathah (فَتْحَتَانِ)

The middle letter keeps the "a" sound in both the past and the present.

• Wazan (Pattern): فَعَلَ — يَفْعَلُ (Fa'ala — Yaf'alu)
• Mauzun (Examples):
  • فَتَحَ — يَفْتَحُ (Fataha — Yaftahu) — To open
  • ذَهَبَ — يَذْهَبُ (Dhahaba — Yadhhabu) — To go

Bab 4: Kasrah → Fathah (كَسْرٌ - فَتْحٌ)

The middle letter has an "i" sound in the past, and changes to an "a" sound in the present.

• Wazan (Pattern): فَعِلَ — يَفْعَلُ (Fa'ila — Yaf'alu)
• Mauzun (Examples):
  • عَلِمَ — يَعْلَمُ ('Alima — Ya'lamu) — To know
  • شَرِبَ — يَشْرَبُ (Syariba — Yasyrabu) — To drink

Bab 5: Dhommah → Dhommah (ضَمَّتَانِ)

The middle letter keeps the "u" sound in both the past and the present. These verbs usually describe qualities or nature.

• Wazan (Pattern): فَعُلَ — يَفْعُلُ (Fa'ula — Yaf'ulu)
• Mauzun (Examples):
  • حَسُنَ — يَحْسُنُ (Hasuna — Yahsunu) — To be good / beautiful
  • كَبُرَ — يَكْبُرُ (Kabura — Yakburu) — To grow big / old

Bab 6: Kasrah → Kasrah (كَسْرَتَانِ)

The middle letter keeps the "i" sound in both the past and the present. This is the rarest group.

• Wazan (Pattern): فَعِلَ — يَفْعِلُ (Fa'ila — Yaf'ilu)
• Mauzun (Examples):
  • حَسِبَ — يَحْسِبُ (Hasiba — Yahsibu) — To think / deem

7. FAQ about Arabic verbs

Q: What is Fi'il Madhi?

A: فِعْلٌ مَاضٍ (Fi'il Madhi) is a past tense verb. It is used to describe an action that is already finished or completed. When you look up a verb in an Arabic dictionary, it is always listed in this past tense form.

Example: كَتَبَ (Kataba / He wrote) or نَصَرَ (Nasara / He helped).

Q: What is Fi'il Mudhari'?

A: فِعْلٌ مُضَارِعٌ (Fi'il Mudhari') is a present or future tense verb. It describes an action that is currently happening, happens regularly as a habit, or will happen in the future. You can easily recognize it by the extra letter added at the beginning of the verb (such as ya-, ta-, a-, or na-).

Example: يَكْتُبُ (Yaktubu / He writes or He is writing) or يَنْصُرُ (Yansuru / He helps or He is helping).

Q: What is Fi'il Amr?

A: فِعْلُ أَمْرٍ (Fi'il Amr) is a command or imperative verb. It is used when you are giving an order, a direct instruction, or making a request to someone you are talking to (second person).

Example: اُكْتُبْ (Uktub! / Write!) or اُنْصُرْ (Unsur! / Help!).

Q: What is Fi'il Tsulatsi Mujarrad?

A: فِعْلٌ ثُلَاثِيٌّ مُجَرَّدٌ (Fi'il Tsulatsi Mujarrad / Bare Three-Letter Verb) is the most foundational form of a verb in Arabic grammar. It consists of exactly three original root letters with absolutely no extra or added letters. For example, the verb كَتَبَ (Kataba / He wrote) is a bare three-letter verb because it contains only its three core consonants.

Q: What are the 6 Chapters (Abwab) of Arabic Verb Conjugation?

A: In صَرْفٌ (Sharaf / Arabic Morphology), the أَبْوَابٌ (Abwab / Chapters or Groups) represent the six distinct vowel patterns that a basic three-letter verb can follow. These chapters track how the short vowels, or حَرَكَاتٌ (Harakat), change on the middle letter when you shift a verb from the Past Tense (فِعْلٌ مَاضٍ - Fi'il Madhi) to the Present Tense (فِعْلٌ مُضَارِعٌ - Fi'il Mudhari').

Q: Why must we learn Arabic verb conjugation with pronouns?

A: Unlike English, where verbs stay mostly the same regardless of who is doing the action (e.g., "I write," "we write," "they write"), an Arabic verb attaches unique prefixes and suffixes to represent the subject. You must learn Pronoun-Based Verb Conjugation, known as إِسْنَادُ الفِعْلِ إِلَى الضَّمَائِرِ (Isnad al-Fi'li ilad Dhama'ir), because it allows you to instantly know who is performing the action based on the specific Pronoun (ضَمِيرٌ - Dhamir), whether it is "I," "you" (singular/plural), "he," "she," "they," or "we."

Q: What is the most common Arabic verb pattern?

A: The most common pattern among the six chapters is Bab 1, which follows the master template فَعَلَ — يَفْعُلُ (Fa'ala — Yaf'ulu). In this pattern, the middle letter carries a فَتْحَةٌ (Fathah / "a" sound) in the past tense and changes to a ضَمَّةٌ (Dhommah / "u" sound) in the present tense. A classic example is كَتَبَ — يَكْتُبُ (Kataba — Yaktubu / to write).
