Sometimes, more than one Indo-European root-word is reconstructed by the scholars exactly alike which is the case with ker. In such cases the concerned look alike root-words are usually given a consecutive number. Thus, there is ker I, as well as ker II, ker III, ker IV, ker V, ker VI, and ker VII (JS-172-80). Each of these has a different meaning or meanings, and from each of these the scholars have derived different Indo-European words. Sometimes scores of Indo-European words may have been derived from a single root-word. For instance, the Indo-European root-word pele (JS-299-300) has been ascribed by the scholars a number of words which occur in Sanskrit, Greek, Latin, Celtic, Anglo-Saxon, German, English, Russian, etc., such as pur, Cawnpore, Singapore, Jodhpur (and all the other place-names with pur in them), pletho, plethoria, plethoric, pleos, pleonasm, pleonastic, Pleiades, poly-, pleois, pleistos, Pliocene, Pleistocene, hoi polloi, polemos, polemics, polis, -polis, Tripoly, Naples, necropolis, acropolis, cosmopolitan, metropolitan, metropolis, Minneapolis, police, polity, policy, politics, politico, Politburo, plenus, plenary, plenum, pleni-, plenitude, plenty, replenish, plein air, pleo, implement, complement, supplement, compliment, pletus, replete, complete, deplete, impletion, repletion, expletive, supply, comply, manipulum, maniple, plus, plural, plurality, pluri-, pluperfect, piu, publicus, public, publican, publicist, publicity, publish, publisher, republic, republican, pueblo, plebs, plebe, plebeian, palpo, palpate, palpitate, impalpable, palpebral, papillon, pavillon, palma, palm, palmer, palmistry, palmetto, llan, Llan-, lawn, full, fulfil, fyllan, fulsome, fill, filler, felan, feel, feeler, feeling, folc, folk, folklore, folkways, folksy, Herrenvolk, Volkswagen, Volkslied, plus a number of other words.

Observe here that the root-word pele does not occur exactly as pele in a number of these words which are derived by the scholars from this root. Many of these derived words not only show variant forms of the root-word pele, but some related phonetic correspondences by which the root has been influenced. This is a phenomenon which also should be kept in mind when in the next chapter we note the Indo-European root-words in their genetic relationship with their Dravidian seed-words, for the corresponding Dravidian seed-words also show their variant forms.

In many cases the Oxford English Dictionary lists scores of columns of words descended from a single root-word. The fact is, considering that millions of words and more than a hundred Indo-European languages have been born out of the common source of Indo-European, each root-word has been ascribed a number of derived words by the scholars. It should be, therefore, underscored here that in order to keep the length of the present work manageable, rarely the derived words of an Indo-European root which has been noted in its genetic relationship with Dravidian, the common source, are pointed out in the next chapter. But the scholars, especially the Dravidian scholars who may not be fully aware of the makeup of the Indo-European languages, should keep in mind that a root has not only yielded a number of words, but on numerous occasions, it may have given birth to corresponding prefixes and/or suffixes which in their turn are fused with numerous other words. As noted earlier, the Dravidian seed-words or "bricks" were shaped or modified to suit the peculiarity of the Indo-European language in which they were put to use to hold up the structure of that linguistic monument, be it Greek, Latin, Germanic, Slavic, Irish, etc. It may be noted here and as we shall witness in the next chapter, the linguistic phenomenon of using a word in conjunction with other words was already set in Dravidian, the common source, itself. As is well known, Dravidian is a showcase of harnessing words as suffixes.
