No, there isn’t!
If you thought that the word الْجَمِيل should be written with a ة, you might have misunderstood the meaning of the sentence. The second part of the sentence is a so called causative description (نَعْت سَبَبِيّ). The sentence …السيارةُ الجميلُ لونُها means: The car whose colour is beautiful. Or: The car with the beautiful colour.
Watch out! The sentence doesn’t mean: The colour of the nice car…
Let us make the difference clear:
The successful student.
The student whose sister is successful
الطَّالِبُ النَّاجِحةُ أُخْتُهُ
Let us check the different parts of the النَّعْت السَّبَبِيّ
Although it is a نَعْت, it doesn’t describe what precedes, but what comes after it.
The word sister (أُخْت) is the thing being described (مَوْصُوف) because it is not the (male) student, who is successful.
Subject; the thing which is being described.
In order to understand the exact meaning of the نَعْت سَّبَبِيّ you could rewrite the sentence with a relative clause اِسمْ إشارة
الطَّالِبُ الذي نَجَحَتْ أُخْتُهُ
These are the rules for the النَّعْت السَّبَبِيّ:
The النَّعْت السَّبَبِيّ is always singular and comes before the subject of the sentence (فاعِل) which is a اِسْم مَرْفُوع
It agrees with the preceding اِسْم in:
* definite/indefinite form (تَعْريف/تَنْكِير)
It agrees with the following اِسْم – which is the فاعِل – in:
* gender (masculine/feminine) (تَنْكِير/ تَأْنِيث)
The noun after it (فاعِل) takes the pronoun which refers to the first subject in the sentence! Notice: the فاعِل is always مَرْفُوع
Let us have a look at some examples to understand the rules:
The man whose brother is honourable came.
جاءَ الرَّجُلُ الْفاضِلُ أَخُوهُ.
The man whose two brothers are honourable came.
جاءَ الرَّجُلُ الْفاضِلُ أَخَواهُ.
Two men whose two brothers are honourable came.
جاءَ رَجُلانِ فاضِلٌ أَخَواهُما.
The two men whose sisters are honourable came.
جاءَ الرَّجُلانِ الْفاضِلةُ أَخَواتُهُما.
Ladies whose sisters are honourable came.
جاءَتْ سَيِّداتٌ فاضِلةٌ أَخَواتُهُنَّ.
The النَّعْت الْحَقِيقِيّ always comes after the noun which it describes. It follows the noun in gender, negated/not negated, case and singular/dual/plural.
The النَّعْت السَّبَبِيّ always comes before the thing which it describes. It is always singular!
