[ˈsaɫ.moː], [ˈsal.mo]
OriginUnknown, possibly from a Celtic/Gaulish word; the common derivation from saliō (“to leap”) has been dismissed as folk etymology. An equation with Proto-Slavic *sòmъ (“catfish”) by Preobraženskij has not been well-received by succeeding Slavists; neither is Finnish sampi (“sturgeon”) likely related.
