MBAR

MBAR is a Primitive Quendian root basically meaning "settle, establish", but took on considerable semantic development.

In origin, MBAR had the meaning of taking up a firm position in a way that seemed suitable and resolving matters that were in confusion or doubt had arisen; basically to make a decision. It was especially applied to the concept of choosing a region for physical occupation by a family or people and ordering it as "home"; it further developed to include the erection of permanent buildings and dwellings.

Tolkien notes that English "'[s]ettle' is in fact, in its various branches of meaning, a very close rendering of the sense of base √MBAR".

MBAR eventually further evolved into concepts of the world as a whole (Q. Ambar / S. Amar) and fate (Q. umbar / S. amarth).
