The study reconstructs the morphology of teen numerals in Central Semitic languages, covering Northwest Semitic, Arabic, and Sabaic. The formation follows a digit-teen order with gender agreement, unlike many other Semitic languages. The digit stems largely align with previous reconstructions, but significant attention is given to the numeral ‘one’, posited as *ʿist-ān- for masculine and *ʿist-ay- for feminine forms, derived from a Proto-Semitic root distinct from the later adjectival *ʾaḥad-. The paper also examines the endings in the teen numerals, showing that the uninflecting *-a likely preserves an ancient feature. The distinct morphology of feminine forms, especially the Northwest Semitic *ʿiśrihi, reflects an innovative feminine suffix *-ihi, also evidenced in Arabic demonstratives. The study concludes that many features of the teen numerals result from both inherited and innovative elements within the linguistic group.
