Google turns up דואר זבל with the meaning spam(? Since I do not know any Hebrew, I looked for word associations e.g. http://tinyurl.com/aw2k4. Sheepishly apologetic if I am wrong ... oh why do people draw me into conversations about things I know not). As spam is garbage, is this the same zevel? And is it the same Semitic root as the one that gives prince?
