Reconstruction:Proto-Mongolic/ǰirguxan

Etymology
Suggested to be a compound of, *jir being the original ordinal number 'two', and *gu(r)ba/n 'three' being the latter component, evidenced by 🇨🇬 being used to count two of female beings in the Secret History, 🇨🇬, and Tungusic teen numeral borrowings from a Mongolic-related language such as suggesting different original numerals in Pre-Proto-Mongolic.

If it is indeed an innovation, the original Pre-Proto-Mongolic root may have been *nil, as suggested by the Jurchen-Manchu borrowings such as and Jin Dynasty  and 🇨🇬.

Compare 🇨🇬.
