The only exception to the rigid Mabni rule within this system is the number twelve ( / Ithna 'Ashara ).

The rules of Tarkib Adadi are remarkably systematic: tarkib adadi

refers to the unique linguistic syntax used in Arabic grammar to construct phrases combining numbers ( adad ) and the objects being counted ( ma'dud ). Unlike many languages where quantification follows a straightforward numerical modifier-noun pattern, Arabic treats numerical phrases with an intricate web of morphosyntactic rules. This structural framework governs grammatical case inflection ( i'rab ), gender agreement, and definitive marking. The only exception to the rigid Mabni rule

These are not compound numbers. They use a possessive construction ( Idafah ) where the number acts as the first term ( mudaf ) and the counted noun acts as a plural genitive second term ( mudaf ilayh ). For example: ثَلَاثَةُ رِجَالٍ ( Thalāthatu rijālin - Three of men).
