Reconstruction:Proto-Semitic/ṯalāṯ-

Perhaps cognate with Egyptian ḫmtw, as are *ṯamāniy- and ḫmnw.

*ṯalāṯ-

1. three

Lipiński reconstructs *śalāṯ- to account for the Ethiopian Semitic and Modern South Arabian forms, and posits that the other Semitic languages underwent regressive assimilation of the first radical, but unless this variation was present at the level of Proto-Semitic, it is more parsimonious to assume that those languages underwent dissimilation instead.

This number exhibited chiastic concord (gender polarity), in which masculine forms were used to agree with feminine nouns, and feminine forms with masculine nouns.
