In linguistics, metatony refers to the change of nature of accent (its intonation, or tone), usually within the same syllable. When the accent also changes its syllable, the process is called metataxis. Metataxis can also be analyzed as a combination of accent movement and metatony. The term is usually used when referring to accentual developments in the history of Baltic and Slavic languages which exhibited numerous such developments, representing the accentual equivalent of sound change. ==Slavic metatony== In South Slavic languages (Serbo-Croatian and Slovene) Proto-Slavic old acute accent ⟨ő⟩ was shortened. Its direct reflex is the short falling accent ⟨ȍ⟩ in standard Serbo-Croatian, whereas standard Slovene has long rising accent ⟨ó⟩ with younger length.〔This is due to secondary lengthening of all non-final syllables. This lengthening, however, has not occurred in all Slovene dialects.〕 * Common Slavic *bra̋trъ "brother" > Serbo-Croatian ''brȁt''/бра̏т, Slovene ''bràt'' In all Serbo-Croatian and Slovene dialects, in nominative singular of o- and i-stems the stem-final syllable of accent paradigm ''c'' words is lengthened. For monsyllabics this amounts to lengthening of short circumflex accent ⟨ȍ⟩ to long circumflex ⟨ȏ⟩: * Common Slavic *bȍgъ "god" > Serbo-Croatian ''bȏg''/бо̑г, Slovene ''bóg'' 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「Metatony」の詳細全文を読む スポンサード リンク
