In historical linguistics, Bartsch's law or the Bartsch effect ((フランス語:loi de Bartsch) or フランス語:''effet de Bartsch'') is the name of a sound change that took place in the early history of the langues d'oïl, for example in the development of Old French. ==Description== Bartsch's law was a phonetic change affecting the open central vowel in northern Gallo-Romance dialects in the 5th-6th century. This vowel, inherited from Vulgar Latin, underwent fronting and closure in stressed open syllables when preceded by a palatal or palatalized consonant. The result of this process in Old French was the diphthong : :Latin > Old French ''laissier'' (modern French ''laisser'' "let") :Latin > Old French ''chier'' (modern French ''cher'' "dear") Note that is also the outcome of the diphthongization of in stressed, open syllables: :Latin > > > Old French ''pie'' (modern French ''pied'' "foot") The chronology of Bartsch's law relative to the more general diphthongization of to (responsible, for example, for the final vowels in > ''mer'' "sea" or > ''porter'' "carry") has not been conclusively established.〔Laborderie (1994), p. 37〕 According to one view, diphthongization took place first, and Bartsch's law is seen as a further segmentation of the diphthong caused by the preceding palatal/palatalized consonant, followed by simplification of the resulting triphthong: :IPA: > > > > :Romanicist notation: á > áę > íaę > íę > íẹ According to a second view, Bartsch's law affected the simple vowel , causing it to change to , which then diphthongized to : :IPA: > > :Romanicist notation: a > ẹ > íẹ Support for the second hypothesis comes the fact that palatal consonants triggered the same change > in unstressed word-initial syllables:〔Zink (1986), p. 108, 115–117〕 :Latin > > Old French ''cheval'' "horse" 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「Bartsch's law」の詳細全文を読む スポンサード リンク
