How do we know it was not rendered into Albanian as Teti - notice the similarity with Deti. We don't know the history of this word. Also, it is claimed that Albanians do not have marine words, so where Deti (sea) came from, what about Anie (ship) etc.
Terra is closest to Toke, I do not know how this word evolved into Albanian, if anyone knows a better explanation, go ahead. I notice that Albanian is usually ignored or seen with skepticism when comparing words of common IE origin. Let's take the Proto IndoEuropean word *kap (grasp) -in Albanian Kap-grasp- this is taken as cognate for German habere, also from Latin capere, from PIE *gap (give) - Albanian jap (give). Which one of the candidates is closest to the PIE root word? The german, latin or Albanian? Also words of common PIE origin shared with slavic languages do not necessarily mean these words came from slavic into Albanian. Every word should be investigated.
Sorry guys but nobody ever read Iapetoc, but I am sure all read the Bullshit of A Kolla
Breg Deti
Greek words Βροχη Virb Bρεχω - Βρεχ-ομαι Βρεχ χ is family of χκγ latin kgc and Β το family of Bpvf
so the word seems to be from same family origin Bρεχ (brech ch as h in Herod) and breg
Now Deti and Thetis
Thetis was God but Virb δυω or Dye or baptise, or make-get wet is also in all forms like noun δυτης etc
remember that aphrodite was ανα-δυω-μενη ana-duo-meni
so the word is simmilar rooted the english word Diver -Dive
in fact is more close due to t and not v
about the word anie (ship) just remember that Athenean word was ναιας-ναυς naias-naus and virb was νεω neo and in plural νηαι-nie (ships)
the root is old Pelasgian - Peleset and is the same root with the Christian Patriarch Noah,
or from Greek times colonies changed through time from naia to anie
personnaly I believe is not an IE word but an Arcado-Cypriot - Levantine- Minor asian
Now about Thetis or Tethys
the Virb Theo Θεω means run Fast, so God = Θεος = The one who runs extremely fast,
in Homer we found her as ηεριη meaning very fast, the other one is Εως eos (morning light)
named as ηρι iri-eri, virb exist also in τρι-ηρεις Trierens means 3 times faster,
according Homer was daughter of Nereus (sea god) but was also the replacer of Titanis Εως Eos
so although sea nymph Thetis or Tethys means fast runner
search the virb θεω
now the word Βροχη βρεχω is considered more new in Greek that the word υετος
while the Homeric is υει -ui and precipitation is υετος, compare with Slavic lie,
about Taranis claim as celtic I can not confirm neither deny since I do not know and must search.
