The Doer of the Verb
In a verbal sentence, the الفاعل (al-fā‘il) is the 'doer' of the action. It always follows the verb and takes the nominative case (usually ending in a damma).
How It Works
The الفاعل (fā‘il) is the grammatical subject of an active verb. It may act, experience something, or undergo a change: مات الرجلُ means “the man died,” without suggesting that he deliberately caused it. To become proficient in identifying it, follow these rules:
- Active Verbs Only: The fā‘il only exists with active verbs. If the verb is passive, the subject is instead called a Nā’ib al-Fā‘il.
- Position: It must follow the verb. If the noun comes before the verb, it is normally analyzed as a Mubtada’. In الطَّالِبُ يَكْتُبُ, الطالب is the topic and يكتب contains a hidden subject pronoun هو referring back to it. With الطُّلَّابُ يَكْتُبُونَ, the attached واو is the verb’s subject.
- Case: It is always marfū‘. While the damma is standard for singular nouns, the fā‘il is marked by Alif in dual nouns and Wāw in sound masculine plurals.
- Attached Pronouns: In the Five Verbs, the attached pronoun (like the Wāw in يكتبون) is the fā‘il, while the nūn is the marker of the verb's indicative mood. See attached pronouns on verbs for more.
- Gender Agreement: The verb matches the fā‘il in gender. However, if the fā‘il is separated from the verb by إلا, the verb remains masculine (e.g., ما قام إلا هند). Also, non-human plurals take a feminine singular verb.
- Number Agreement: In VSO order, the verb remains singular even if the fā‘il is dual or plural.
- Types: A fā‘il can be an explicit noun, an attached pronoun, or a clause acting as a noun. If no visible doer is present, the fā‘il is a 'hidden' pronoun (Mustatir).
A Clause as Subject: يَجِبُ أَنْ تَدْرُسَ means “you must study.” The clause أن تدرس acts as the subject of يجب. With passive and linking verbs, different grammatical labels apply; “every verb has a فاعل” is not a rule covering every Arabic verb construction.

In the Five Special Nouns, the nominative marker for the fā‘il is a wāw instead of a damma.

For broken plurals of non-humans, the verb is usually feminine singular ('tajrī'), regardless of the noun's original gender.

The two teachers arrived, and the engineers attended.
Word by Word: Arrived the two teachers, and attended the engineers.
المعلمان is nominative dual with ا; المهندسون is nominative sound masculine plural with و. Both preceding verbs stay singular.
Common Mistakes
Making the verb plural to match a plural subject in VSO order.
يأكلون الطلابُ التفاحَ.يأكلُ الطلابُ التفاحَ.In Modern Standard Arabic, if the verb comes before a plural subject, the verb must remain singular.
Swapping the endings of the doer and the object.
Different Meaningساعدَ الرجلَ الطفلُ.ساعدَ الرجلُ الطفلَ.ساعدَ الرجلَ الطفلُ is correct, but it means "the child helped the man", because the doer is the noun with the nominative (-u) ending. To say "the man helped the child", give the man the -u ending: ساعدَ الرجلُ الطفلَ.
How It Connects
Learn This First
To understand the 'Doer' (الفاعل), a learner must first be familiar with the structure of verbal sentences in Arabic. Since the doer is the one performing the action, knowledge of basic verb forms (like the past tense) is required. Additionally, because the doer is always marked by the nominative case (marfu'), the learner needs to understand the concept of case endings to correctly identify the doer in a sentence.
- The Past Tense
The doer is defined by its relationship to a verb; understanding how verbs function in the past tense provides the necessary context for identifying who performed the action.
Level 1 - The Subject Ending
The doer (الفاعل) is always in the nominative case (مرفوع), typically marked by the -u ending (damma), so understanding this case is vital for correct identification and pronunciation.
