أَفْعَالُ التَّكْوِينِ وَالفِعْلُ المَنْصُوبُ بَعْدَ لِكَيْ
The ecosystem verbs with their complements, both conditional types applied to threats, and the لِكَي purpose clause with its subjunctive verb.
What does the structure communicate?
Which word or ending changes?
What must match the noun or person?
Can you use it with new vocabulary?
يَضُمُّ takes a direct object.
Type 2 counterfactual.
لِكَيْ + subjunctive تَحْمِيَ.
يَضُمُّ / يُشَكِّلُ + object
Both take a direct object; يَتَفَاعَلُ takes مَعَ.
إِذَا + past → سَـ
A likely consequence of a current trend.
لَوْ + past → لَـ
What would have been better.
لِكَيْ + verb (final fatḥa)
لِكَي triggers the subjunctive.
| Structure | Marker | Example |
|---|---|---|
| يَضُمُّ | direct object | يَضُمُّ آلَافَ الأَنْوَاعِ |
| Type 1 | إِذَا … سَـ | إِذَا اسْتَمَرَّ … سَتَمُوتُ |
| Type 2 | لَوْ … لَـ | لَوْ حُمِيَتْ … لَبَقِيَتْ |
| لِكَيْ | subjunctive fatḥa | لِكَيْ تَحْمِيَ |
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.
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 P4 accuracy depends on it.

Every answer checks a stated rule, change or agreement decision.
Build · transform · justify
The guided builder develops flexible sentence construction. The three independent tasks then test different skills: grammatical transformation, meaning and coherence, and original sentence production.
Combinatorial builder studio
This guided builder accepts 27 accurate combinations. Build 3 different sentences, changing one meaningful chunk each time. Compare the grammar and meaning before moving to the independent tasks.

Each composition, threat and purpose clause is accurate on its own, so any three different combinations work.
Fix the subjunctive after لِكَيْ
Repair the verb after لِكَيْ so it is subjunctive.نَحْتَاجُ إِلَى قَوَانِينَ لِكَيْ نَحْمِي الغَابَاتِ.
لِكَيْ + مَنْصُوبٌAfter لِكَي the verb takes a fatḥa (the subjunctive): نَحْمِيَ.
Remove the extra preposition
Repair the sentence so يَضُمُّ takes a direct object.تَضُمُّ الغَابَةُ بِآلَافِ الأَنْوَاعِ.
يَضُمُّ + مَفْعُولٌ بِهِيَضُمُّ takes a direct object.
Fix the Type 2 result
Repair the counterfactual so it uses لَـ.لَوْ حُمِيَتِ الشِّعَابُ مُبَكِّرًا، سَتَبْقَى بِخَيْرٍ.
لَوْ … لَـ + مَاضٍA Type 2 result takes the لَـ prefix on a past verb.
0/3 purposeful tasks secured.

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.
A Type 2 result takes لَـ, not سَـ.
