مُرَكَّبٌ بِنَائِيٌّ

مُرَكَّبٌ بِنَائِيٌّ is a phrase in which two numerals are joined to form a single word (number).

Rule:

1. A حَرْفٌ originally linked two numbers.

Example: أَحَدَ عَشَرَ (eleven) was originally أَحَدٌ وَ عَشَرٌ

This phrase is found only in numbers 11-19. أَحَدَ عَشَرَ, إِثْنَا عَشَرَ, ثَلَاثَ عَشَرَ, ….. تِسْعَ عَشَرَ

2. Both parts of this phrase will always be مَفْتُوْحٌ except the number 12 (إِثْنَا عَشَرَ).

Example for رَفْعٌ state:

جَاءَ أَحَدَ عَشَرَ رَجُلًا

Eleven men came

No change to phrase despite in رَفْعٌ

Example for نَصْبٌ state:

رَأَيْتُ أَحَدَ عَشَرَ رَجُلًا

I saw eleven men

No change to phrase despite in نَصْبٌ.

Example for جَرٌّ state:

مَرَرْتُ بِأَحَدَ عَشَرَ رَجُلًا

I passed by eleven men

No change to phrase despite in جَرٌّ.

3. As for number 12 (إِثْنَا عَشَرَ), its second part is always مَفْتُوْحٌ, while the first part changes إِعْرَابٌ:

• In رَفْعٌ it is written as إِثْنَا عَشَرَ with an ا at the end of the first part.
• In نَصْبٌ and جَرٌّ, it is written as إِثْنَيْ عَشَرَ with ي in place of the ا.

Example for رَفْعٌ state :

جَاءَ إِثْنَا عَشَرَ رَجُلًا

Twelve men came

First part changed due to رَفْعٌ.

Example for نَصْبٌ state:

رَأَيْتُ إِثْنَيْ عَشَرَ رَجُلًا

I saw twelve men

First part changed due to نَصْبٌ.

Example for جَرٌّ state:

مَرَرْتُ بِإِثْنَيْ عَشَرَ رَجُلًا

I passed by twelve men

First part changed due to جَرٌّ.
