If we take the name for the IE peoples amongst the western and southern to be of the form He[l/r] where H is a glotal, e a front vowel and [l/r] to be an intermediate consonant NB Hellenes, Erin, Iran, Armenian Then this is often combined with a suffix from the local IE dialect meaning 'of the people' Taking one case as an example HI[l/r] = talis ( L: of such a kind ) = of the IE peoples Now with the passage of time, the H could be dropped and [l/r] absorbed into the t yielding Italis from which can be derived Latin Italia and Itali orum
Note. The origional IE form from wich the bronze age form comes: Ke(l/r) where K represents the unvoiced Velar Take the word Slav for instance using a form of the plural genitive we have: Ke(l/r)av Applying the first IE palatization we have: Se(l/r)av then Metathesis: S(l/r)eav Choosing l and merging vowels leads of course to Slav, which then naturally has overtones of glorious. We can see this same variation of the choice of l or r in the North West assuming the voicing of K to G occuring in the Iron Age. We have in the West: Gallic and in the East: German
