释义 |
Siebs's law is a Proto-Indo-European (PIE) phonological rule named after the German linguist Theodor Siebs. According to this law, if an s-mobile is added to a root that starts with a voiced or aspirated stop, that stop is allophonically devoiced. Compare: PIE {{PIE|*bʰr̥Hg-}} > Latin fragor, but {{PIE|*s-bʰr̥Hg-}} > PIE {{PIE|*spʰr̥Hg-}} > Sanskrit sphūrjati. DiscussionSiebs proposed this law in the Zeitschrift für vergleichende Sprachforschung auf dem Gebiete der indogermanischen Sprachen, as Anlautstudien (Berlin, 1904, 37: 277–324). Oswald Szemerényi has rejected this rule, explaining that it is untenable and cites the contradiction present in Avestan zdī from PIE {{PIE|*s-dʰi}} "be!" as counterproof (Szemerényi 1999: 144). However, the PIE form is more accurately reconstructed as {{PIE|*h₁s-dʰí}} from {{PIE|*h₁es-}} (so not an s-mobile) and thus Siebs's law appears to demand that the sibilant and aspirated stop are both adjacent and tautosyllabic, something which is known to only occur in word-initial position in Proto-Indo-European anyway.
