Notice above that the Dravidian words manifesting the correspondence between initial k and initial s are listed in different group numbers. Note also that there are numerous other examples than the above listed seventy-five which also demonstrate this phonetic correspondence in Dravidian. But this correspondence is not universal in Dravidian because initial k remains the same in many Dravidian languages (which is noted by DED also), and this can be easily witnessed by anyone who has DED available to him or her, because the corresponding words are listed in the same groups which have words beginning with k.

Thus, as astonishing as it may seem, in spite of the great period of time which has elapsed since the ancient Dravidians left India for the shores of Europe, Dravidian is still able to demonstrate that she not only has the phonetic correspondence which has qualified some Indo-European languages to be called as the Satem-languages, but that she has the phonetic correspondence which has qualified some other Indo-European languages to be referred to as the Centum-languages. This, of course, is another linguistic proof the significance and implication of which, along with the other correspondences which we witnessed above, well adorns Dravidian as the common source of Indo-European. In view of the fact that biological terms such as family (family of languages), tree (family tree of languages or words), roots (root-words), etc., have well-served in Linguistics, it is in order to call these Dravidian phonetic correspondences as Dravidian birthmarks, because not only these correspondences occur between different Dravidian languages, but many times within the same language which goes to point out an earlier period when these correspondences were being born or that they were in their infancy in Dravidian. Thus, these unique phonetic correspondences are her own birthmarks which she has bequeathed to her sons and daughters in Europe and they in their turn have carried them upon themselves as badges proclaiming and proving their genetic bond with their mother Dravidian.

It is important to note and keep in mind that these phonetic birthmarks which Dravidian possesses and which she has bequeathed to her European offspring are, indeed, unique, and not underestimate their uniqueness, significance and implication. Their uniqueness can be realized when we observe the simple fact that such things as mispronouncing words or names may cause disastrous results in such transactions as commercial or legal, let alone in daily lives.

Now, as noted above, Germanic turns k into h (see Pei-22-23). Like the others we have witnessed so far, this is also an extremely important phonetic correspondence in Indo-European not only because Germanic thus distinguishes itself among the western members of Indo-European, but because while a remarkable number of Germanic words (which include related English words) begin with h, the Indo-European root-words beginning with h are relatively very few (JS-143-46 lists only six root-words beginning with h). This points out that a number of Indo-European root-words beginning with k have been responsible for scores of German and English words which begin with h. Here, the fact of the matter is that not only Dravidian has the phenomenon of initial k generally remaining the same in many Dravidian languages (which is reflected by the Centum-languages in Indo-European), and that it has the phenomenon of initial k often becoming s (which is reflected by the Satem-languages in Indo-European), but it also has the phonetic phenomenon of initial k often becoming h! The extraordinary significance and implication of the existence of this threefold linguistic phenomenon in Dravidian itself in the context of the identity of the common source of Indo-European is crystal clear to all scholars of languages.
