ᴹ√BER root. “valiant”
A root in The Etymologies of the 1930s glossed “valiant”, its most notable derivative is the name S. Beren “Bold”. It had a variety of derivatives having to do with daring, such as ᴹQ. verya-/N. bertha- “to dare” and ᴹQ. verya/N. beren “bold”. The continued appearance of the name Beren in the later versions of The Silmarillion implies the root remained valid, but this name was only translated in The Etymologies of the 1930s, so it could have shifted in meaning.
