The root idea of the verb b-r-k is "bend the knee," and the root is found throughout the Semitic family of languages' with this mean- ing.
How can the root be found if, as you're claiming, it is the root? You have to go to something before b-r-k (b-r-q) to get to the root. It's a derivative of the other, previous word.
