köken: From Proto-Tai *ʰlenꟲ (“great-grandchild”). Southwestern Tai languages have tone A such as Thai เหลน [leːnᴬ¹] probably due to contamination from Proto-Tai *ʰlaːnᴬ (“grandchild”). In Southwestern Tai, cognate with Lao ເຫຼນ (nrē) or ເຫຼັນ (len), Lü ᦜᦲᧃ (l̇iin), Shan လိၼ် (lǐn). In Northern Tai, cognate with Zhuang laenj.
köken: From შვილთა (švilta) + შვილი (švili), meaning a child of children. Children in this sense indicates the 3 degrees of separation, i.e. one’s own child, then one’s child’s child/grandchild and then comes the grandchild’s child.
Etimoloji
