【摘要】 “毛”的通语字音，上古音在段玉裁的“古音二部”，中古音为“明母豪韵平声”，现代汉语为[mau35]，从古至今都没有发生大的变化。但根据古书记载，“毛”的方俗字音有很多，如“毧隹、苗、无、模、轑、爸”等，它们与通语字音在声、韵、调上有各类不同的差异；通过对全国各地现代汉语方言的观察，发现“毛”的部分方音在声、韵、调上分别出现了鼻音化塞音[mb]作声母、鼻音韵尾单独作韵母、平声变读上声等特殊情况，这些是继承古代方音的表现，由此反观出吴语、粤语、闽语、客家话的语音发展程度与通语的不同。更多还原

【Abstract】 The general phonetic sound of "Mao" has been no obvious change since ancient times.However,according to the records of ancient books,there are many dialect pronunciations of "Mao",such as "Yi,Miao,Wu,Mu,Lao,Ba",which are different from those of general language in consonants,vowels and tones.Through the observation of modern Chinese dialects all over the country,it is found that some local sounds of "Mao" have special situations,such as nasalization plosives [mb],nasal ending as final consonant alone,and level tone changing to falling-rising tone.These are the manifestations of inheriting ancient local sounds.And it also reflected that the phonetic development degree of Wu language,Guangdong language,Fujian language and Hakka language is different from that of general language.更多还原
