Yesterday, after dealing with my Mg.Gr. Mele, I was reminded of a parallel lexical situation: Gall in Mg.Gr. is Fele; in Latin it is Fel/Fellis, which is the basis of many European cognate words -- Fiel, Fiele, etc. Again, my Fele is unique and presumably derived directly from a Cl. Greek word, but I haven't been able to find it in some Gr. lexicons. The attested KholE` (= Gall) does not seem to be a cognate of Fell/Fellis or of Fele, as only the lambda sound is sheared by the words in question. So, even the issue about the origin of the Latin word is left open. // Today I found interesting posts in an Italian website: Somebody proposed that Ital. Fiele came about by an imitation to Miele (= Honey), from Lat. Mel/Mellis, but he did not realize that the derivation [by a Latin speaker] would be from the root of the word, namely Mell-. Likewise, the derivation of Fiele from Lat. Fel/Fellis should be from the root, namely Fell-.
Incidentally, they mention a Latin motto that contains the contraposition of Gall [bitter] and Honey [sweet] -- already made prosaically by some Greek writers -- Ubi Mel, ibi Fell -- = Where there is honey, there is gall/bile. [I was familiar with this type of formulation from a medieval German monk, who knew Latin authors: Ubi Amor, ibi Deus = Where there is Love, there is God. // Following that Latin motto contraposition, they suspected that the etymology of Fiele and the like was not a normal one. So, I suspect that my Mg.Gr. Fele derived, albeit abnormally, from the Latin word rather than Cl. Gr. PhElo- , which connotes deception. [Fiele was already used in medieval Latin, obviously from nominative Fel rather than Fell-.] //
PhEloO = I deceive; cheat ; Lat. Fallo. According to the Liddell-Scott Greek Lexicon, this Gr. verb is the archaic SphEloO with the loss of the initial S. My native dialect has SBALLU (= I flunk; go broke), which apparently harkens back to the archaic Greek verb rather than the Latin verb. // Doing etymologies is not an easy task, as it is already evident in Plato's "Cratylus".
