على

On

Level 1

على (ʿalā) is a core preposition in Arabic. Its most basic use is to describe physical location (on top of a surface), but it also expresses duty ('upon you'), hostility ('against'), and fixed directions ('to the right').

How It Works

1. Physical Location and 'On'
The primary use of على is to indicate being on a surface. As a حرف جر (preposition), it triggers the genitive case (usually ending in kasra).

2. Morphological Changes
When followed by a noun, it ends in alif maqṣūra (ى). When a pronoun suffix is attached, the ى changes to a regular ي (yā’).

  • على + ك = عَلَيْكَ (on you)
  • على + ي = عَلَيَّ (on me) - uses a shaddah.

3. Phonological Harmony
When attaching third-person pronouns (like -hu or -hum), the vowel of the pronoun shifts from a 'u' to an 'i' for easier pronunciation after the yā’: عَلَيْهِ (on him) and عَلَيْهِم (on them).

4. Case Markers for Plurals
While singular nouns take a kasra, remember that dual nouns and sound masculine plurals change their marker to ي (yā’) when following a preposition.

5. Idiomatic Expressions
على is used in many fixed phrases. Examples include 'على فكرة' (by the way) and 'على كل حال' (in any case). It can also mean 'against' in contexts of competition.

6. Expressing Obligation
Arabic uses 'على + [person]' to express that something is a duty or necessity, similar to saying 'It is incumbent upon you'.

Examples (6)

  1. الكِتابُ على الطّاوِلَةِ.

    The book is on the table.

    Word by Word: The book [is] on the table.

    This shows the basic use of 'على' for physical location. The following noun takes the genitive case.

  2. على كُلِّ حالٍ، الجَوُّ جَميلٌ.

    In any case, the weather is beautiful.

    Word by Word: On every case, the weather [is] beautiful.

    This demonstrates an idiomatic use of 'على' in the fixed phrase 'على كل حال' (in any case).

  3. على فِكْرَةٍ، أنا جائِعٌ.

    By the way, I am hungry.

    Word by Word: On a thought, I [am] hungry.

    The phrase 'على فكرة' is a common idiom meaning 'by the way'.

  4. على الرَّغْمِ مِن البَرْدِ، خَرَجَ الوَلَدُ.

    Despite the cold, the boy went out.

    Word by Word: On the despite from the cold, went out the boy.

    This uses the fixed expression 'على الرغم من' to mean 'despite'.

  5. على الطُّلابِ أَنْ يَكْتُبوا.

    The students must write.

    Word by Word: Upon the students that they write.

    Using 'على' followed by a noun or pronoun expresses obligation or duty.

  6. سَلَّمْتُ على المُعَلِّمينَ.

    I greeted the teachers.

    Word by Word: I greeted on the teachers.

    This shows how sound masculine plurals change their ending to -īn after a preposition.

Common Mistakes

  • Using 'على' for time expressions like 'on Monday'.

    سأراك على يوم الاثنين.
    سأراك يوم الاثنين.

    In Arabic, you do not use 'على' for days of the week. You either use no preposition or the preposition 'في' (in).

  • Forgetting the spelling change when adding a pronoun.

    علىه
    عليه

    When a pronoun is attached to 'على', the final ى must change to a ي.

  • Confusing 'على' (on) with 'عن' (about/away from).

    تحدثنا على الفيلم.
    تحدثنا عن الفيلم.

    While they sound similar, 'على' means 'on' and 'عن' means 'about'. Use 'عن' when discussing a topic.
