流遇二攝脣音關係補正

A Further Discussion on the Relationship Between the Labial Words in Yu She(遇攝) and the Labial Words in Liu She(流攝)

除"不、浮"二字外,南宋末期大部分尤侯韻脣音字已併入遇攝,在主元音相近的前提下,加之聲母同化作用,二者合併是語言自然演變的結果。"不"字在《中原音韻》等韻書中雖屬於魚模韻,卻並非因尤侯韻脣音字併入遇攝所致。"浮"字是擴散式演變下的産物,在尤侯韻脣音字演變影響下,在宋代南北方小部分地區已讀同遇攝。而遇攝字押入流攝、尤侯韻非脣音字押入遇攝只是個别地區的特殊演變,並不具有普遍性。

Except for the words"bu"(不)and"fu"(浮),most of the labial words in You/Hou rhymes(尤侯韻)in the late Southern Song Dynasty,have converged into the Yu She(遇攝).Given the resemblance of the main vowels and the assimilation of initials,the convergence is the result of natural evolution of language.The word"bu"(不)belongs to Yu/Mu rhymes(魚模韻)in the later rhyme books,such as Zhongyuan Yinyun,but it isn’t the result of the convergence of the labial words in You/Hou rhymes(尤侯韻)into the Yu She(遇攝).The word"fu"(浮)is the product of the diffused evolution,so by the influence of labial words in You/Hou rhymes(尤侯韻),the word"fu"(浮)has converged into the Yu She(遇攝)at some certain area in the Song Dynasty.However the phenomenon that some words in Yu She(遇攝)converged into Liu She(流攝)and that the unlabial words in You/Hou rhymes(尤侯韻)converged into Yu She(遇攝)are an unique evolution in certain regions,but not an universal one.
