The Declinable and the non-Declinable – الْمُعْرَبُ وَالْمَبْنِيُّ  

The declinable nouns – الأَسْمَاءُ الْمُعْرَبَةُ

• The majority of Arabic nouns are declinable. The general rule of the nouns is that they experience declension, so the indeclinable nouns are an exception to the rule. We will learn in this part the rules related to the declinable nouns In-Shaa’-Allaah (God willing).
• Any declinable noun has many possible changes (declensions) in its ending according to its grammatical case and to its position in the sentence. There are many positions that the noun can occupy in the sentence. There are also many forms that affect the sign (vowel ending) of the noun. Let’s first study the grammatical cases of the noun and then we can study the different signs of each case.

1. The grammatical cases of the noun:

• To understand the vowel ending of a declinable noun you first have to know the grammatical case of the noun. The grammatical case of any noun can be nominative, accusative or genitive depending on the position which the noun occupies in the sentence. In this language course we learn which nouns are in the nominative case, which are in the accusative case and which are in the genitive case.
• Some examples of nouns in the nominative case (which will be studied in later lessons) are:

• Some examples of nouns in the accusative case (that will also detailed in later lessons):

• Some examples of nouns in the genitive case (that will also detailed in later lessons):

• From the above mentioned examples we understand clearly that the noun’s position in the sentence determines its grammatical case and the different positions of the nouns will be the main topics of the coming lessons In-Shaa’-Allaah (God willing).
• Once we distinguish the noun’s position and grammatical case, we can automatically think about the sign of the ending of the noun. This will be detailed in the next point:

2. The sign of the ending of the declinable noun:

• The nominative noun is originally signed with đammah on its end, the accusative is originally signed with fatħah and the genitive is originally signed with kasrah. The original signs occur when the noun is in the basic form. If the noun is not in the basic form (i.e. dual, sound plural etc.) we have to use the secondary signs. Therefore we will have many signs for each case (original signs and secondary signs).
• The following table summarizes the ending signs of the nouns according to the grammatical cases and different reasons for taking the original sign or secondary sign in each case:

• Please remember that the above mentioned secondary signs and their reasons will be studied in detail in later lessons In-Shaa’-Allaah (God willing). This summary is supposed to be a guide to the coming lessons and to show you that the declinable nouns have many forms (of declension) based on many factors.
