This paper presents a systematic reassessment of STURTEVANT’S LAW (Sturtevant 1932), which governs the differing outcomes of Proto-Indo-European (PIE) voiced and voiceless obstruents in Hittite (Anatolian). I argue that STURTEVANT’S LAW was a conditioned pre-Hittite sound change whereby (i) contrastively voiceless word-medial obstruents regularly underwent gemination (cf.Melchert 1994), but gemination was blocked for stops in pre-stop position; and (ii) the inherited [+/-voice] contrast was then lost, replaced by the [+/-long] opposition observed in Hittite (cf. Blevins 2004). I provide empirical and typological support for this novel restriction, which is shown not only to account straightforwardly for data that is problematic under previous analyses, but also to be phonetically motivated, a natural consequence of the poorly cued durational contrast between voiceless and voiced stops in pre-stop environments. I develop an optimality-theoretic analysis of this gemination pattern in pre-Hittite, and discuss how this grammar gave rise to synchronic Hittite via “transphonologization” (Hyman 1976, 2013). Finally, it is argued that this analysis supports deriving the Hittite stop system from the PIE system as traditionally reconstructed (contra Kloekhorst 2016, Jäntti 2017).
