Yesterday, an adventurous etymology idea occurred to me. The word in question is the Celtic word (which was also borrowed into Germanic) for 'iron',
*îsarnon. I have seen attempts to derive it from PIE
*h1esh2er/n- 'blood' (reconstructed from Anatolian and Tocharian data), perhaps due to the reddish colour of rust (iron as the 'bleeding metal'?). But I also have seen attempts to connect it to Basque
izar 'star' - which, I must say, shows some resemblance to PIE
*h2ster-. Which doesn't necessarily invalidates the connection between the Celtic and Basque words, though.
But then it occurred to me that one may leave the poor Basques out of this, there are enough bogus ideas involving their language. Perhaps
*îsarnon descends from the reflex of
*h2ster-no- in some unknown IE language. Well, by invoking an "unknown IE language", one can "prove" anything and nothing, so this is not really worth more than an idea to pursue in my Hesperic conlangs
