Szemerényi's law (or Szemerényi's lengthening) is both a sound change and a synchronic phonological rule that operated during an early stage of the Proto-Indo-European language (PIE). Though its effects are evident in many reconstructed as well as attested forms, it did not operate in late PIE, having become morphologized (with exceptions reconstructible via the comparative method). It is named for Hungarian linguist Oswald Szemerényi. ==Overview== The rule deleted coda fricatives *s or laryngeals *h₁, *h₂ or *h₃ (cover symbol *H), with compensatory lengthening occurring in a word-final position. In other words: : */-VRs/, */-VRH/ > *-VːR : */-VRH-/ > *-VR- (no examples of ''s''-deletion can be reconstructed for PIE) 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Szemerényi's law」の詳細全文を読む スポンサード リンク
