Reconstruction:Proto-Mongolic/modun

Reconstruction
Due to unexplained vowel length in Mongghul, Dagur and East Yugur, some authors posit a primary vowel length (as opposed to secondary lengths from -VxV- sequences) for Proto-Mongolic. However, this idea hasn't reached wide acceptance.

One possible explaination for the length is analogy with hypothetical unsuffixed *mo, which would be regularly lengthened.

Equally unexplained is the retroflex segment found in Bonan and Kangjia, where the *-d- is reflected as -(r)t-.

Etymology
Analyzable as by internal reconstruction. possibly reflects a suffix denoting countable and individualizable objects: compare, , , , and.

Perhaps related by borrowing (either between each other or a common source) with 🇨🇬, see 🇨🇬. Another interesting external comperandum is 🇨🇬.
