The dual in Arabic - الْمُثَنَّى

In Arabic, the linguistic beauty of expressing pairs is captured by the dual form, a grammatical feature absent in many languages. This form is articulated by a distinct set of suffixes, carefully chosen based on the case and gender of the nouns.

1. General Dual Formation: The fundamental blueprint for crafting the dual form requires affixing the combination of a fatha, an alif, and finally, a noon endowed with a kasrah, represented as:

• ـانِ

2. Nominative Case (حَالةُ الرَّفَعِ): When dealing with nouns in the nominative case, a slight variation in suffix emerges. Here, the suffix takes on the pattern of a fatha, a sukoon, and subsequently a noon accompanied by a kasrah:

• ـيْنِ

3. Accusative and Genitive Cases for Masculine Nouns: Masculine nouns, when in the accusative or genitive cases, adhere to the aforementioned patterns. It’s crucial to recognize the case to apply the appropriate suffix, ensuring grammatical correctness and preserving the eloquence of the Arabic language.
