乔克托语形态中的韵律限制

韵律环绕理论（McCarthy & Prince 1990 a）是解决将规则域限制为小于形态成分的问题的一般方法。例如，在阿拉伯语的单数/复数对ndub/anaadib“蝗虫”和sul aan/salaa iin“苏丹”中，最后一个音节的元音长度保持不变，尽管单词其余部分的形状发生了重大变化。韵律界限理论将单数碱基划分为受影响的（aun，sul）和未受影响的（dib，diaan）部分，只有受影响的部分映射到轻重（或抑扬格）模板上。
The theory of PROSODIC CIRCUMSCRIPTION (McCarthy & Prince 1990a) is a general approach to the problem of limiting the domain of rules to less than a morphological constituent. For example, in the Arabic singular/ plural pairs ndub/anaadib ‘locust’ and sulṭaan/salaaṭiin ‘sultan’, vowel length in the final syllable remains unaltered despite significant changes in the shape of the rest of the word. Prosodic circumscription theory partitions the singular base into affected (aun, sul) and unaffected (dib, ṭaan) portions, with only the affected portion mapped onto a light–heavy (or iambic) template.
