What does Tanween Kasr mean?

Tanween kasr is the genitive counterpart of tanween fath. It looks like two stacked kasras below the letter and produces an "-in" sound at the end of an indefinite singular noun in the genitive case. Unlike tanween fath, it does not require a support letter.

Tanween kasr appears at the end of indefinite nouns after prepositions (مِنْ كِتَابٍ "from a book") or in genitive constructions. The mark sits below the letter — both visually and grammatically it parallels kasra.

Frequently asked questions

❓ Frequently Asked Questions

How do I type tanween kasr on the Arabic keyboard?

On the Arabic 101 keyboard layout, hold Shift and press G. Type the base letter, then Shift+G to add tanween kasr — for example, ب, then Shift+G produces بٍ.

Does tanween kasr need a support alif like tanween fath does?

No. Unlike tanween fath, tanween kasr is written directly on the final letter without any additional alif. كِتَابٍ is complete as-is — you do not write كِتَابٍي or similar.

When is tanween kasr used in Arabic grammar?

It marks an indefinite singular noun in the genitive case. The genitive case is required after most prepositions (مِنْ بَيْتٍ "from a house"), in idafa constructions (the second noun of a possessive pair), and after certain particles. In casual spoken Arabic the case endings are usually dropped.
