Lesson

1. What Will We Learn in This Level?

● In this eighteenth level, we will review and compare indeclinable and diptote nouns. ● We will learn the case chart and use of indeclinable nouns. ● We will compare fully declinable, diptote, and indeclinable nouns. ● We will write the three case positions of all remaining diptote nouns in the exercise.

2. Case Chart for Indeclinable Nouns

● Only 2 percent of Arabic nouns are indeclinable (mabnī) and never change their visible form. ● Important indeclinable kalimahs and their cases: Base/meaning Nominative Accusative Genitive هٰذَا (this) هٰذَا هٰذَا هٰذَا ذٰلِكَ (that) ذٰلِكَ ذٰلِكَ ذٰلِكَ الَّذِي (the one who) الَّذِي الَّذِي الَّذِي ● These indeclinable kalimahs have no visible case marker. Their grammatical case is understood as nominative, accusative, or genitive from their position in the sentence.

3. Final Comparison and Summary of Grammatical Case

● Compare fully declinable, diptote, and indeclinable nouns together: Type Basic difference Case examples Fully declinable muʿrab All three cases have different forms shown by tanwīn رَجُلٌ / رَجُلًا / رَجُلٍ Diptote muʿrab No tanwīn; the genitive takes fatḥah instead of kasrah, so there are only two forms زَيْنَبُ / زَيْنَبَ / زَيْنَبَ Indeclinable noun Its form does not change when its case changes, so it has only one form هٰذَا / هٰذَا / هٰذَا

4. Case Chart for Diptotes (Part One)

● Learn the nominative, accusative, and genitive forms of these diptote names of prophets and women: Nominative Accusative Genitive آدَمُ آدَمَ آدَمَ إِسْحَقُ إِسْحَقَ إِسْحَقَ يَعْقُوبُ يَعْقُوبَ يَعْقُوبَ عَائِشَةُ عَائِشَةَ عَائِشَةَ

5. Case Chart for Diptotes (Part Two)

● Learn the nominative, accusative, and genitive forms of these diptote nouns: Nominative Accusative Genitive مَرْيَمُ مَرْيَمَ مَرْيَمَ طَلْحَةُ طَلْحَةَ طَلْحَةَ عَدْنَانُ عَدْنَانَ عَدْنَانَ مِصْرُ مِصْرَ مِصْرَ هَارُوتُ هَارُوتَ هَارُوتَ

6. Level Summary

● An indeclinable noun keeps exactly the same form and pronunciation in all three cases, such as هٰذَا and ذٰلِكَ. ● Fully declinable nouns take three forms, diptotes take two forms with fatḥah instead of kasrah, and indeclinable nouns take only one form. ● We completed the case forms and meanings of the remaining diptote nouns in the exercises, including آدَمُ, مَرْيَمُ, and طَلْحَةُ.
