6th chief of the House of Bëor (S/148). His name is simply the noun [N.] bregolas “fierceness” used as a name (Ety/BERÉK).

Conceptual Development: In The Etymologies from the 1930s, the name N. Bregolas was translated “Fierceness” and was given as a derivative of the root ᴹ√BEREK along with N. bregol “fierce” (Ety/BERÉK), which is the source of the derivation given above.
