According to Mallory we have the following PIE words (in this notation, g = palatal/plain ġ=plain/uvular):

a̯enġhu̯is snake (> уж)

a̯enghus narrow (> узко)

a̯enghnos fear, constriction (> ужас)

This hints at that the words could be related if the exact value of the g was determined wrongly.

I also wonder whether the following words are related:

e̯oġhu̯is snake, serpent (in Fortson, e̯eghu̯is). Mallory claims this is unrelated to the a̯enġhu̯is. Fortson claims it is related to the following entry and reconstructs the same consonant in the root. Mallory claims that the "traditional school" derived hedgehog as "snake-eater". The Brill etymological dictionary of Latin reconstructs the initial a̯- here and links this root to the a̯enġhu̯is, claiming that the -n- infix appeared here due to analogy.

e̯eghis hedgehog (> russ. ёж, eng. hedgehog)

e̯eghs out

e̯egherom lake (> russ. озеро)

If e̯oġhu̯is, it could be connected to e̯eġhu̯ti drinks

  • This question is, actually, about PIE, and even not about the Slavic languages in general. In the Slavic languages the 2 words are not related. – Yellow Sky Feb 24 '13 at 5:31

    So what? The question is, actually, about etymology of two modern Russian words. Ulike posting Modern Russian endings onto Proto-Slavic words, it's fine. – Manjusri Feb 24 '13 at 10:38
  • @Manjusri But the question is off topic here. This site is for Russian, the current modern language. Questions like this are better for the Linguistics site. – Alenanno Feb 24 '13 at 12:33

  • @Alenanno Right, let's delete each and every question with tags pertaining to language history then. I doubt the question being off-topic here. It's about the history of Russian language. – Manjusri Feb 24 '13 at 15:53
