The Root KAU in KAULINS on the Basis of Bantu Evidence Might Be an Ancient Term for Man Generally

In the posting below, crossposted from Lingwhizt, one can read that KAU is a Bantu term for "Young Man" and that KU meant "man", so that we need not wonder in Latvian that KUNGS means "Sir, Mr." and KUNDZE "Lady, Mrs.".
We are simply dealing in the case of Latvian with a very old stratum of human language.

Hence, KAU could be the root term for the origin of the name KAULINS, especially when one looks at the Bantu terms for a human clan: e.g Kolo in the Asu language of Bantu, koa in the Bamba language of Bantu and xolo in the Bukusu language of Bantu. The Rumanyo variant koro shows the L and R shift while the Yao kósjò is very much like the Yao word kòòsè for "all". Basically, even the English term clan is not that far from these Bantu words, i.e. we might humorously say the clan is the same term as Kaulini "the Kaulinses".

In any case, the name Kaulins will be very old.
