Reconstruction:Proto-Mongolic/-sun

Etymology
Unclear meaning. Doerfer and Poppe suggests it was a singularity marker for countable concepts in Pre-Proto-Mongolian since it was dropped when the plural affix was added in words such as. However, it is also present in many uncountable words, especially after a monosyllabic root such as, , and , leading to its interpretation as a collective suffix by Han Nugteren or a class suffix for uncountable homogeneous substances by Juha Janhunen.

Most likely a Mongolic morphological innovation since it is only present in Mongolic languages and absent in Para-Mongolic languages, compare 🇨🇬 vs., 🇨🇬 vs. , and 🇨🇬 vs.. Lexical correspondences in neighboring languages also suggest Mongolic innovation such as in 🇨🇬 vs., 🇨🇬 vs. , and 🇨🇬 vs..
