أن / أنّ

أن Versus أنّ

Level 3

أنْ (an) connects a verb to a preceding action/desire (like 'to' in English). أنّ (anna) introduces a factual clause (like 'that' in English) and must be followed by a noun or pronoun.

How It Works

In Modern Standard Arabic, these two particles are both 'infinitive-forming' (masdariyya), meaning they turn the clause that follows them into a virtual noun. However, they serve different semantic and grammatical roles:

1. أنْ (an) - The Action Linker
This particle links a main verb to a non-established action (such as a desire, hope, or intent). It is followed by a verb in the subjunctive mood. In the subjunctive, singular verbs take a fatha (-a), while the Five Verbs (dual, masculine plural, and 2nd person feminine singular) indicate the mood by dropping the final nun.
Example: أحب أنْ أشربَ القهوة (I like to drink coffee).

2. أنّ (anna) - The Fact Linker
One of the Sisters of Inna, this particle introduces an established fact, belief, or cognition (knowing, hearing, perceiving). It must be followed by a noun or a pronoun suffix. The noun following it is always in the accusative case. أنّ is also used after prepositions to form conjunctions like لأنّ (because).
Example: أظنّ أنّكَ تعبان (I think that you are tired).

Key Differences:

  • Meaning: أنْ is for potential actions (wanting, needing); أنّ is for established facts (knowing, claiming).
  • Followed by: أنْ is followed by a verb; أنّ is followed by a noun or pronoun.
  • Grammar: أنْ triggers the subjunctive (fatha or dropping nun); أنّ triggers the accusative case for the following noun.

  1. أريدُ أنْ أدرسَ اللغةَ العربيةَ.

    I want to study the Arabic language.

    Word by Word: I want that I study the language the Arabic.

    Here, أنْ is followed by a present tense verb, which must take the subjunctive mood ending (-a).

  2. أعرفُ أنّ الامتحانَ صعبٌ.

    I know that the exam is difficult.

    Word by Word: I know that the exam difficult.

    Here, أنّ is used to introduce an established fact. It is followed by a noun in the accusative case.

  3. سألتُهُ بعدَ أنْ وصلَ إلى البيتِ.

    I asked him after he arrived home.

    Word by Word: I asked him after that he arrived to the house.

    أنْ often follows temporal prepositions like بعد (after) to link to a specific action.

  4. غبتُ لأنّني كنتُ مريضاً.

    I was absent because I was sick.

    Word by Word: I was absent because that I was sick.

    The particle أنّ combines with prepositions like لِـ to form conjunctions like 'because', followed by a pronoun suffix.

  5. يجبُ أنْ تذهبوا الآنَ.

    You (plural) must go now.

    Word by Word: It is necessary that you go now.

    In the subjunctive mood, the Five Verbs (like 'you all go') indicate the mood by dropping the final nun.

Common Mistakes

  • Using أنّ directly before a verb without a pronoun.

    أعتقد أنّ يذهب إلى البيت.
    أعتقد أنّه يذهب إلى البيت.

    أنّ must be followed by a noun or a pronoun. If you want to follow it with a verb, you must attach a pronoun suffix like -hu (annahu).

  • Using أنّ after the verb 'to say'.

    قال أنّ الامتحان سهل.
    قال إنّ الامتحان سهل.

    After any form of the verb قال (to say), you must use إنّ (with a kasra) instead of أنّ.

  • Forgetting to drop the 'nun' in plural subjunctive verbs after أنْ.

    يجب أن تذهبون.
    يجب أن تذهبوا.

    When using أنْ with plural verbs, you must apply the dropping of the nun to correctly form the subjunctive.

Learn This First

To distinguish between 'أن' and 'أنّ', a learner must first understand the basic sentence structures in Arabic (nominal vs. verbal). They also need to be familiar with the individual functions of 'أن' (which precedes verbs in the subjunctive mood) and 'أنّ' (which precedes nouns or pronouns to state facts).
