That Albanian is of clearly Indo-European
origin was recognized by the German philologist, Franz Bopp, in 1854;
the details of the main correspondences of Albanian with Indo-European
languages were elaborated by another German philologist, Gustav Meyer,
in the 1880s and 1890s. Further linguistic refinements were presented
by the Danish linguist Holger Pedersen and the Austrian Norbert Jokl.
The following etymologies illustrate the relationship of Albanian to Indo-European
(an asterisk preceding a word denotes an unattested, hypothetical Indo-European
parent word, which is written in a conventionalized orthography): pes‘
"five" (from *pˇnk e); zjarm "fire" (from *g hermos);
nat‘ "night" (from *nok t-); dh‘nd‘r "son-in-law"
(from * gem ter-); gjarp‘r "snake" (from *sˇrpon-); bjer "bring!"
(from *bhere); djeg "I burn" (from *dheg ho); kam "I have"
(from *kapmi); pata "I had" (from *pot-); pjek "I roast"
(from * peko); thom, thot‘ "I say, he says" (from *k'emi, *k'et
. . .).
