Awareness about Basic Guttural Consonants, BGC, perdurable presence, since illo tempore, in Hamito-Semitic languages, and conspicuous absence among Indo-European and Uralic languages, raises a case of interest. Tunsi Long Range Comparison, LRC, with English and Suomi languages entails discovery of regular differences, alternations, and reversal patterns hidden in the data. A brand new approach emerges facilitating languages LRC, and easing Language Origins Research, LOR. My first claim is about an unvoiced consonant gamut available to offset each missing BGC. My second claim covers the useful, nontrivial, unobtrusive, original consonantal reversal phenomenon. The Cassidy Code is Sumerian, Grimm and Verner Laws sequel, alternating BGC with mostly unvoiced consonants or apocope entailing a forward shift of articulation basis, due finer pronunciation, and adding the transmogrifying reversals. The idea is to put forward a parallel code, in LRC of languages and LOR quests, to the focus on separate wide swaths of straight cognations.
