The اسم المرة (Ism al-Marrah) is the 'Noun of Instance.' It turns a general action into a countable event, specifically meaning 'one time.' For example, while 'hitting' is a concept, an Ism al-Marrah makes it 'a blow' or 'one hit.'

How It Works

The اسم المرة is essential for precision in Modern Standard Arabic. It allows speakers to quantify actions without needing complex phrasing.

1. Formation from Form I (Triliteral) Verbs:
The standard pattern is فَعْلَة.

  • نظر (to look) becomes نظرة (a glance/one look).
  • دقّ (to knock) becomes دقّة (a knock).

2. Formation from Derived Verbs (Forms II-X):
Take the مصدر and add a ة.

  • انطلق (to launch) → Masdar: انطلاق → Ism al-Marrah: انطلاقة (one launch).
  • ابتسم (to smile) → Masdar: ابتسام → Ism al-Marrah: ابتسامة (a smile).

3. The 'One' Rule (Important):
If the base مصدر already ends in a ة, you must add the word واحدة to specify it happened once.

  • Form I Example: The Masdar of رحم (to have mercy) is رحمة. To say 'one act of mercy,' you must say رحمة واحدة.
  • Derived Example: The Masdar of أجاب (to answer) is إجابة. To say 'one answer,' you must say إجابة واحدة.

4. Weak Roots:
In hollow verbs, the middle vowel returns to its root origin. For defective verbs, the final weak letter is treated similarly.

  • قام (hollow) → قَوْمَة (one standing up).
  • رمى (defective) → رَمْيَة (one throw).

5. Restrictions:
The Ism al-Marrah cannot be formed from deficient verbs like كان, frozen verbs like بئس, or verbs describing permanent innate qualities like حسُن (to be handsome).

Examples (4)

  1. لِكُلِّ جَوادٍ كَبْوَةٌ.

    Every horse has a stumble.

    Word by Word: For every horse [is] a stumble.

    Here, 'kabwah' is the Ism al-Marrah of 'kabā' (to stumble), indicating a single instance of stumbling.

  2. طَرَقَ البابَ طَرْقَةً واحِدَةً.

    He knocked on the door once.

    Word by Word: He knocked [on] the door a knock one.

    While 'tarqah' already implies once, adding 'wāḥidah' provides extra emphasis.

  3. اسْتَراحَ المُسافِرُ اسْتِراحَةً واحِدَةً.

    The traveler took one rest.

    Word by Word: Rested the traveler a rest one.

    Because the Masdar 'istirāḥah' already ends in a taa marbuta, 'wāḥidah' is mandatory to indicate a single instance.

  4. أَكَلْتُ أَكْلَةً سَريعَةً.

    I ate a quick meal.

    Word by Word: I ate an eating quick.

    'Aklah' is the Ism al-Marrah of 'akala' (to eat), referring to a single event of eating (a meal).

Common Mistakes

  • Confusing the Noun of Instance with the Noun of Manner.

    جَلَسْتُ جِلْسَةً واحدةً.
    جَلَسْتُ جَلْسَةً واحدةً.

    The Ism al-Marrah (Instance) uses a fatha (a) on the first letter: jalsah. The Ism al-Hay’ah (Manner) uses a kasra (i): jilsah, meaning 'a way of sitting' or 'posture.'

  • Expecting دعوة alone to stress "one time".

    Different Meaningدَعَوْتُهُ دَعْوَةً.
    دَعَوْتُهُ دَعْوَةً واحِدَةً.

    'Daʿwah' is the standard Masdar for 'to invite/call,' so on its own it can be read as the act of inviting in general. The first sentence is correct, but it does not stress 'one'. Add 'wāḥidah' to make clear you mean one invitation, as an instance.
