Understanding Obligation in Arabic
Obligation in Arabic can be expressed in different ways, depending on the level of necessity and the formality of the context. Just as in English, there are strong and weak forms of obligation, as well as formal and informal ways to convey the idea that something “must” be done.
1. Using the Verb “يجب” (yajibu) – Must/Have to
The verb يجب (yajibu) is the most common way to express strong obligation in Arabic. It is equivalent to “must” or “have to” in English. It is usually followed by the preposition أن (an) and a verb in the present tense (المضارع).
Structure: يجب + أن + [present tense verb]
Examples:
- يجب أن تدرس كل يوم. (You must study every day.)
- يجب أن أذهب الآن. (I have to go now.)
Note that يجب is not conjugated for the subject, but the verb following أن matches the subject in person and number.
2. Using “لا بد من” (la budda min) – It is necessary to
لا بد من is a formal expression meaning “it is necessary to.” This phrase is often used in writing, news, and formal speech.
Structure: لا بد من + [noun or verbal noun (masdar)]
Examples:
- لا بد من العمل الجاد لتحقيق النجاح. (It is necessary to work hard to achieve success.)
- لا بد من الحضور غداً. (Attendance tomorrow is necessary.)
You can also use لا بد أن + verb for a similar meaning:
- لا بد أن تذهب الآن. (You must go now.)
3. Using “مفروض” (mafroud) and “مطلوب” (matloub) – Supposed to/Required
The word مفروض (mafroud) means “supposed to” or “ought to,” while مطلوب (matloub) means “required.” These are used in both formal and informal contexts to indicate expectation or requirement.
Examples:
- مفروض أن تأتي في الوقت المحدد. (You are supposed to come on time.)
- مطلوب من الجميع احترام القوانين. (Everyone is required to respect the laws.)
4. Using “على” (ala) + Pronoun – It is on [someone] to
This construction is commonly used to express that it is a person’s responsibility or duty to do something. The preposition على is followed by a pronoun and then the verb.
Structure: على + [pronoun] + أن + [present tense verb]
Examples:
- عليك أن تدرس بجد. (You have to study hard.)
- علينا أن نساعد الآخرين. (We have to help others.)
5. Using Modal-Like Verbs – Should/Ought to
For weaker forms of obligation or giving advice, Arabic often uses verbs such as ينبغي (yanbaghi) or يستحسن (yustahsan).
Examples:
- ينبغي أن تذهب إلى الطبيب. (You should go to the doctor.)
- يستحسن أن تبدأ مبكراً. (It is advisable to start early.)
Tips for Using Obligation in Arabic Conversation
- Choose the right level of formality: Use يجب or لا بد من in formal contexts, and على + pronoun in everyday conversation.
- Practice conjugating the verb after أن to match the subject.
- Listen to native speakers and note which structures are used in different situations.

Common Mistakes to Avoid
- Don’t conjugate يجب for the subject; conjugate the following verb instead.
- Don’t confuse يجب أن with يمكن أن (can/may), which expresses possibility, not obligation.
- Remember that لا بد من is usually followed by a noun or masdar, not a verb in its infinitive form.
