Talk:πέτρα

I seriously doubt the etymology. Petra is also said of cliffs which are all but a "passage".

Minimally, this etymology requires a reference.

 * I agree, although the semantic reasons are not the strongest argument. The OED cites "J. P. Maher (1977 in Current Issues Ling. Theory 125–37)" as suggesting an origin in 🇨🇬, but I would like an opinion from Beekes and the like, placed in the entry and referenced. ? —Μετάknowledge discuss/deeds 07:58, 3 September 2017 (UTC)
 * Beekes is kind of a "meh". I don't know what possible semantic relationship to could be. — JohnC5 08:09, 3 September 2017 (UTC)
 * Maher evidently thinks that came first, with the idea of "projectile" > "rock". Referencing Beekes to say that it's unknown is better than the unreferenced hypothesis that was there before. —Μετάknowledge discuss/deeds 08:15, 3 September 2017 (UTC)

Suggested cognate
LolPacino (talk) 05:37, 21 August 2020 (UTC) Would Sanskrit Prastara (प्रस्तर) (from where-Hindi Patthar (पत्थर)) be cognate with πέτρα
 * The Sanskrit word is formed from +  so it means "that which is strewn forth", referring to rocks and pebbles. It was obviously a synchronic formation, but if it were a PIE word it'd be something like . Its Greek reflex would have been quite different. -- Bhagadatta (talk) 08:18, 21 August 2020 (UTC)
