Al-Murakkabāt — Compound Numerals, the Twelve Exception and Declining Baalbek

1. Al-Murakkabāt — The textbook definition

كُلُّ اسْمٍ رُكِّبَ مِنْ كَلِمَتَيْنِ، لَيْسَتْ بَيْنَهُمَا نِسْبَةٌ
Translation: Every noun formed from two words, without a predicative or genitive relationship between them.

Here compound does not mean just any adjacent words. The two elements form one special numerical expression or name. The clause without a relationship excludes normal sentences and iḍāfah constructions from this chapter’s immediate scope.

2. What “no relationship” excludes

In عَبْدُ اللَّهِ, there is an iḍāfah: عَبْدُ is the first term and اللَّهِ is the genitive second term.
In قَامَ زَيْدٌ, there is predication: an action is attributed to Zayd.
In بَعْلَبَكّ, two elements combine into a single proper name, rather than an ordinary genitive phrase.

When applying the book’s definition, first rule out a normal iḍāfah or predicative relationship. These comparisons are added teaching examples.

3. Compound numerals — Fixed components

فَإِنْ تَضَمَّنَ الثَّانِي حَرْفًا، يَجِبُ بِنَاؤُهُمَا عَلَى الْفَتْحِ، كَـ«أَحَدَ عَشَرَ» إِلَى «تِسْعَةَ عَشَرَ»
Translation: If the second component contains the sense of a particle, both elements must be built on fatḥ, as in the numbers 11 through 19.

The dual pronoun in بِنَاؤُهُمَا refers to both parts. It is not just the second word whose final form stays fixed. The author immediately gives a special exception for twelve.

4. What “built on fatḥ” means

Both أَحَدَ and عَشَرَ have their fixed final fatḥah in أَحَدَ عَشَرَ.
Being indeclinable means that their endings do not change like those of an ordinary declinable noun when the expression functions as subject, object or after a preposition.

Nevertheless, the whole compound has a changing syntactic position: nominative, accusative or genitive position. Distinguish the fixed outward form from its grammatical role.

5. Eleven as the subject

جَاءَ أَحَدَ عَشَرَ طَالِبًا — Eleven students came.
جَاءَ: past verb built on fatḥ.
أَحَدَ عَشَرَ: compound numeral, both components fixed on fatḥ, in the nominative position as subject.
طَالِبًا: accusative numerical specification (tamyīz).

Why: Do not change the numeral to «أَحَدُ عَشَرُ» because it is a subject. Its fixed endings do not prevent it from having a nominative syntactic role. This sentence is an instructional addition.

6. Eleven as an object

رَأَيْتُ أَحَدَ عَشَرَ طَالِبًا — I saw eleven students.
رَأَيْتُ: past verb plus a connected subject pronoun in the nominative position.
أَحَدَ عَشَرَ: compound numeral fixed on fatḥ in both parts, in the accusative position as direct object.
طَالِبًا: accusative tamyīz.

Compared with the preceding sentence, the whole numeral’s syntactic role has changed, but its internal endings have not.

7. Eleven after a preposition

مَرَرْتُ بِأَحَدَ عَشَرَ طَالِبًا — I passed by eleven students.
مَرَرْتُ: past verb plus first-person subject pronoun.
بِـ: preposition.
أَحَدَ عَشَرَ: fixed two-part numeral in the genitive position after بِـ.
طَالِبًا: accusative numerical specification; the preposition does not make the tamyīz genitive.

Key point: The final fatḥah on «عَشَرَ» is a sign of indeclinable form, not an accusative case ending here.

8. One shape, three syntactic positions

جَاءَ أَحَدَ عَشَرَ طَالِبًا — the numeral is subject, in the nominative position.
رَأَيْتُ أَحَدَ عَشَرَ طَالِبًا — it is the direct object, in the accusative position.
مَرَرْتُ بِأَحَدَ عَشَرَ طَالِبًا — it follows a preposition, in the genitive position.

All three use the same outward form أَحَدَ عَشَرَ. The position changes, not the fixed endings.

9. Forms 11–15 in one set

For masculine counted nouns, these are the first five forms:
11 — أَحَدَ عَشَرَ
12 — اِثْنَا عَشَرَ / اِثْنَيْ عَشَرَ — the exception.
13 — ثَلَاثَةَ عَشَرَ
14 — أَرْبَعَةَ عَشَرَ
15 — خَمْسَةَ عَشَرَ

Do not treat 12 exactly like the other fixed compounds; its special declension is explained next. This full list is a teaching expansion of the source’s 11–19 range.

10. Forms 16–19 complete the range

The remaining forms for masculine counted nouns are:
16 — سِتَّةَ عَشَرَ
17 — سَبْعَةَ عَشَرَ
18 — ثَمَانِيَةَ عَشَرَ
19 — تِسْعَةَ عَشَرَ

Together with the preceding slide, all nine numbers from 11 through 19 are shown. 12 is the exception; both parts of 11 and 13–19 are fixed on fatḥ.

11. The counted noun as tamyīz

حَضَرَ ثَلَاثَةَ عَشَرَ طَالِبًا — Thirteen students attended.
ثَلَاثَةَ عَشَرَ: two-part numeral, fixed on fatḥ, in the nominative position as subject.
طَالِبًا: singular accusative tamyīz clarifying the number.

The specification after numbers 11–99 is normally singular and accusative. That is why we have «طَالِبًا», not «طَالِبُونَ». This is added teaching explanation, not a separate quoted rule from the source.

12. A short feminine counted-noun example

حَضَرَتْ إِحْدَى عَشْرَةَ طَالِبَةً — Eleven female students attended.
إِحْدَى عَشْرَةَ: compound numeral in the nominative position as subject; its two components are fixed on fatḥ, with an estimated fatḥah on the first component’s final alif maqṣūrah.
طَالِبَةً: singular accusative tamyīz.

عَشْرَةَ is the feminine-counted form. The numeral’s gender shape changes, but the general indeclinability rule still applies.

13. Twelve — The special exception

إِلَّا «اثْنَيْ عَشَرَ»، فَإِنَّهَا مُعْرَبَةٌ كَالْمُثَنَّى
Translation: Except “twelve”, which is declined like the dual.

To unpack the book’s concise statement, separate the components: اثنا/اثني changes like a dual, whereas عَشَرَ remains fixed on fatḥ. The whole expression is therefore not described by exactly the same “both parts fixed” rule as the other compound numerals.

14. Twelve in the nominative

جَاءَ اثْنَا عَشَرَ طَالِبًا — Twelve students came.
جَاءَ: past verb.
اثْنَا: nominative subject marked by alif, as with the dual.
عَشَرَ: second numeral component, built on fatḥ.
طَالِبًا: accusative tamyīz.

If twelve were completely like eleven, its first component would not vary by case. The nominative form uses «اثْنَا».

15. Twelve in the accusative

رَأَيْتُ اثْنَيْ عَشَرَ طَالِبًا — I saw twelve students.
رَأَيْتُ: past verb plus the subject pronoun.
اثْنَيْ: accusative direct object marked by yāʾ on the dual pattern.
عَشَرَ: second part, fixed on fatḥ.
طَالِبًا: accusative tamyīz.

The shift اثْنَا → اثْنَيْ follows the governing syntax; it is not an arbitrary alternate spelling.

16. Twelve in the genitive

مَرَرْتُ بِاثْنَيْ عَشَرَ طَالِبًا — I passed by twelve students.
بِـ: preposition.
اثْنَيْ: genitive after the preposition, marked by yāʾ on the dual pattern.
عَشَرَ: fixed second part.
طَالِبًا: accusative tamyīz.

Accusative and genitive share the form «اثْنَيْ», but the syntactic reasons differ: object position in one case, a preposition in the other.

17. Eleven versus twelve

جَاءَ أَحَدَ عَشَرَ طَالِبًا — for 11, both parts are fixed; the numeral has a nominative position.
جَاءَ اثْنَا عَشَرَ طَالِبًا — for 12, the first part is nominative with alif.
رَأَيْتُ اثْنَيْ عَشَرَ طَالِبًا — for 12, the first part is accusative with yāʾ.

Summary: For eleven, state the syntactic position of the whole fixed phrase; for twelve, also identify the changing case marker on the first element.

18. The feminine form of twelve

جَاءَتِ اثْنَتَا عَشْرَةَ طَالِبَةً — Twelve female students came.
اثْنَتَا: nominative subject marked by alif on the dual pattern.
عَشْرَةَ: second part fixed on fatḥ.
طَالِبَةً: accusative numerical specification.

رَأَيْتُ اثْنَتَيْ عَشْرَةَ طَالِبَةً — here «اثْنَتَيْ» is accusative with yāʾ. This is an added feminine parallel to the book’s masculine twelve example.

19. Baalbek — Mixed inflection

وَإِنْ لَمْ يَتَضَمَّنْ ذَلِكَ، فَفِيهَا لُغَاتٌ، أَفْصَحُهَا: بِنَاءُ الْأَوَّلِ عَلَى الْفَتْحِ، وَإِعْرَابُ الثَّانِي إِعْرَابَ غَيْرِ الْمُنْصَرِفِ، كَـ«بَعْلَبَكّ»
Translation: If the second part does not have that feature, more than one form of usage exists; the most eloquent makes the first element indeclinable with fatḥ and declines the second like a diptote, as in Baalbek.

Important difference: Both elements are not fixed on fatḥ. The first is fixed, while the second declines like a diptote.

20. The two elements of Baalbek

بَعْلَبَكّ is a single compound proper name made from «بَعْلَ» and «بَكّ».
بَعْلَ: first component, built on fatḥ in the book’s preferred analysis.
بَكّ: second component, declined like a diptote.

This is the proper name of a city, not an ordinary “first term + genitive term” construction. You need two different grammatical analyses within the one compound.

21. Recall the diptote rule

Under the ordinary diptote rule, nominative takes ḍammah, while accusative and genitive take fatḥah, without tanwīn.
The second element of Baalbek therefore appears as:
Nominative — بَعْلَبَكُّ
Accusative — بَعْلَبَكَّ
Genitive — بَعْلَبَكَّ

The first element بَعْلَ remains fixed on fatḥ. The added vowels are pedagogical; the source prints the three example clauses unvowelled.

22. The book’s three example clauses

نَحْوُ: جَاءَنِي بَعْلَبَكّ، وَرَأَيْتُ بَعْلَبَكّ، وَمَرَرْتُ بِبَعْلَبَكّ
Translation: For example, Baalbek came to me; I saw Baalbek; and I passed by Baalbek. These serve as technical case-parsing examples.

The printed source writes بعلبك without final vowels in each position. In analysis, the second part receives the appropriate case ending, while the first element’s fatḥah remains fixed.

23. Parsing: جَاءَنِي بَعْلَبَكُّ

جَاءَنِي بَعْلَبَكُّ — Baalbek came to me.
جَاءَ: past verb.
نِ: protective nūn (nūn al-wiqāyah), with no syntactic case position.
ي: attached object pronoun, accusative position.
بَعْلَ: first component of the proper name, built on fatḥ.
بَكُّ: second component with visible nominative ḍammah; the whole name is the subject.

Only the second component takes nominative ḍammah; the first stays on fatḥ.

24. Parsing: رَأَيْتُ بَعْلَبَكَّ

رَأَيْتُ بَعْلَبَكَّ — I saw Baalbek.
رَأَيْتُ: past verb with a connected nominative subject pronoun.
بَعْلَ: first component, built on fatḥ.
بَكَّ: second component with visible accusative fatḥah; the whole name is the direct object.

The first fatḥah is indeclinable structure; the last fatḥah marks accusative case. They look alike but do different jobs.

25. Parsing: مَرَرْتُ بِبَعْلَبَكَّ

مَرَرْتُ بِبَعْلَبَكَّ — I passed by Baalbek.
مَرَرْتُ: past verb with an attached subject pronoun.
بِـ: preposition.
بَعْلَ: first part, built on fatḥ.
بَكَّ: second part, genitive with fatḥah in place of kasrah, because it behaves as a diptote.

Critical point: The fatḥah on «بَكَّ» is not accusative here; it marks the genitive case.

26. The same fatḥah can have different reasons

In رَأَيْتُ بَعْلَبَكَّ, the second part is accusative; its fatḥah marks the accusative.
In مَرَرْتُ بِبَعْلَبَكَّ, it is genitive; fatḥah stands in place of the expected kasrah for this diptote.

The final vowel alone does not identify the case. Identify the governing element: the verb makes an object; the preposition governs genitive.

27. A natural sentence using the city name

زُرْتُ بَعْلَبَكَّ — I visited Baalbek.
زُرْتُ: past verb plus attached nominative subject pronoun.
بَعْلَ: first part built on fatḥ.
بَكَّ: second part accusative with fatḥah; the whole name is direct object.

The book uses «رَأَيْتُ بَعْلَبَكّ». This more natural travel sentence is an added teaching example applying the same rule.

28. Baalbek after another preposition

سَافَرْتُ إِلَى بَعْلَبَكَّ — I travelled to Baalbek.
سَافَرْتُ: past verb plus subject pronoun.
إِلَى: preposition.
بَعْلَ: fixed first part.
بَكَّ: genitive with fatḥah under the diptote rule.

The same principle holds after other suitable prepositions, not only بِـ: the final component is genitive but takes fatḥah in place of kasrah.

29. Proper-name compound versus iḍāfah

غُلَامُ زَيْدٍ — Zayd’s servant.
غُلَامُ: first term of iḍāfah, declined according to its sentence role.
زَيْدٍ: genitive second term with kasrah.

بَعْلَبَكُّ — a compound proper name.
بَعْلَ: first component built on fatḥ.
بَكُّ: second component nominative as a diptote.

Both look multi-part, but one is a genitive construction, while the other is a single compound proper name.

30. Proper-name compound versus a clause

قَامَ زَيْدٌ — Zayd stood.
قَامَ: past verb.
زَيْدٌ: nominative subject.

بَعْلَبَكُّ مَدِينَةٌ — Baalbek is a city.
بَعْلَبَكُّ: topic; a compound proper name with a fixed first part and nominative second part.
مَدِينَةٌ: nominative predicate.

قَامَ زَيْدٌ is a clause; بَعْلَبَكّ is one compound noun, not itself a sentence.

31. Why the source mentions variants

فَفِيهَا لُغَاتٌ، أَفْصَحُهَا ...
Translation: There are several usages; the most eloquent among them is ...

The author acknowledges variant treatments but selects one as the most eloquent and explains that treatment in the main text. This lesson teaches that preferred pattern.

We do not attribute a complete catalogue of the other readings to this short quotation, because the source’s main paragraph does not enumerate them.

32. Comparing the book’s two branches

أَحَدَ عَشَرَ — both parts fixed on fatḥ, with the whole expression occupying a syntactic case position.
اثْنَا/اثْنَيْ عَشَرَ — first part declines like the dual, while the second stays fixed.
بَعْلَبَكّ — first part built on fatḥ, second declined like a diptote.

Conclusion: Merely knowing that an expression combines two words does not determine its case behavior; identify which type of compound it is.

33. Three examples for guided analysis

1. حَضَرَ أَحَدَ عَشَرَ رَجُلًا — the numeral is in the nominative position, both parts fixed.
2. حَضَرَ اثْنَا عَشَرَ رَجُلًا — «اثنا» is nominative with alif, «عَشَرَ» fixed.
3. حَضَرَ بَعْلَبَكُّ — «بَعْلَ» fixed and «بَكُّ» nominative with ḍammah.

All three act as subjects, yet their endings behave differently because the internal construction of each compound differs.

34. Repairing common parsing errors

Error 1: Changing «أَحَدَ» to «أَحَدُ» solely because the compound is the subject. Correction: the fixed numeral is in the nominative position.
Error 2: Calling both elements of «اثْنَا عَشَرَ» equally indeclinable. Correction: the first declines as a dual.
Error 3: Calling the fatḥah in «مَرَرْتُ بِبَعْلَبَكَّ» accusative. Correction: it is genitive marking on the diptote-like second component.

Identify the governor, position and actual sign separately rather than memorizing labels without analysis.

35. Lesson synthesis

This chapter’s compounds have two key patterns.
11 and 13–19: both parts are fixed on fatḥ; the whole numeral has a syntactic case position.
12: the first part follows dual case endings (alif / yāʾ); the second remains fixed.
بَعْلَبَكّ: the first part is built on fatḥ; the second declines as a diptote.

Decide case behavior from the type of compound and its governing syntax, not just the look of a final vowel. The next source chapter is al-Kināyāt.
