Objectives and visible success

Name ecosystem and biodiversity vocabulary in scientific register.
Describe composition with يَضُمُّ، يُشَكِّلُ، يَتَفَاعَلُ مَعَ.
Weigh a real threat (إِذَا) against a counterfactual (لَوْ).
Form a purpose clause with لِكَي + a subjunctive verb (final fatḥa).

You can show success when…

I use يَضُمُّ and يُشَكِّلُ with direct objects.
I use إِذَا … سَـ for a real risk and لَوْ … لَـ for a counterfactual.
I put a fatḥa on the verb after لِكَي (تَحْمِيَ, not تَحْمِي).
I describe an ecosystem before arguing about its protection.

Tick achievements as you secure them.

تَضُمُّ الشِّعَابُ المَرْجَانِيَّةُ فِي البَحْرِ الأَحْمَرِ أَلْفَ نَوْعٍ مِنَ الأَسْمَاكِ

What to notice

يَضُمُّ takes a direct object.

لَوْ كَانَتْ إِجْرَاءَاتُ الحِمَايَةِ أَصْرَمَ سَابِقًا، لَكَانَتِ الشِّعَابُ أَفْضَلَ حَالًا

What to notice

Type 2 counterfactual.

تَحْتَاجُ الدُّوَلُ إِلَى تَعَاوُنٍ لِكَيْ تَحْمِيَ هٰذَا الإِرْثَ الطَّبِيعِيَّ

What to notice

لِكَيْ + subjunctive تَحْمِيَ.

Composition

يَضُمُّ / يُشَكِّلُ + object

Both take a direct object; يَتَفَاعَلُ takes مَعَ.

تَضُمُّ الغَابَةُ آلَافَ الأَنْوَاعِيُشَكِّلُ المَرْجَانُ بِيئَةً حَيَوِيَّةً

Real threat (Type 1)

إِذَا + past → سَـ

A likely consequence of a current trend.

إِذَا اسْتَمَرَّ الاحْتِرَارُ، سَتَتَبَيَّضُ الشِّعَابُ وَتَمُوتُ

Counterfactual (Type 2)

لَوْ + past → لَـ

What would have been better.

لَوْ كَانَتِ الحِمَايَةُ أَصْرَمَ سَابِقًا، لَكَانَتِ الشِّعَابُ أَفْضَلَ حَالًا

Purpose subjunctive

لِكَيْ + verb (final fatḥa)

لِكَي triggers the subjunctive.

تَحْتَاجُ المِنْطَقَةُ إِلَى تَعَاوُنٍ لِكَيْ تَحْمِيَ إِرْثَهَا الطَّبِيعِيَّ

Structure	Marker	Example
يَضُمُّ	direct object	يَضُمُّ آلَافَ الأَنْوَاعِ

Type 2	لَوْ … لَـ	لَوْ حُمِيَتْ … لَبَقِيَتْ
لِكَيْ	subjunctive fatḥa	لِكَيْ تَحْمِيَ

يَضُمُّ and يُشَكِّلُ describe composition

تَضُمُّ الشِّعَابُ المَرْجَانِيَّةُ آلَافَ الأَنْوَاعِ (encompasses thousands of species), يُشَكِّلُ المَرْجَانُ بِيئَةً حَيَوِيَّةً (forms a vital environment). Both take a direct object. يَتَفَاعَلُ مَعَ links the parts of a system.

لِكَي puts the next verb in the subjunctive

After لِكَي the verb ends in a fatḥa, not a ḍamma: نَحْتَاجُ إِلَى قَوَانِينَ لِكَي نَحْمِيَ الغَابَاتِ (so that we protect — نَحْمِيَ, not نَحْمِي). The final fatḥa is the subjunctive marker, and TC accuracy depends on it.

Strong learners do not only recognise an error: they identify the system and repair it.

نَحْتَاجُ إِلَى قَوَانِينَ لِكَيْ نَحْمِي الغَابَاتِ.

نَحْتَاجُ إِلَى قَوَانِينَ لِكَيْ نَحْمِيَ الغَابَاتِ.

After لِكَي the verb is subjunctive: نَحْمِيَ, with a final fatḥa.

تَضُمُّ الغَابَةُ بِآلَافِ الأَنْوَاعِ.

تَضُمُّ الغَابَةُ آلَافَ الأَنْوَاعِ.

يَضُمُّ takes a direct object, with no preposition.

لَوِ اسْتَمَرَّ الاحْتِرَارُ، سَتَمُوتُ الشِّعَابُ.

لَوِ اسْتَمَرَّ الاحْتِرَارُ، لَمَاتَتِ الشِّعَابُ.
