一类是以元音收尾或没有韵尾的,叫“阴声韵”.2.古无轻唇音,即上古时没有轻唇音“非、敷、奉、微”,中古时的轻唇音“非、敷、奉、微”来自于“帮、滂、并、明”,由清代学者钱大昕提出。
3.一般用在动词或形容词后面。
使用“貌”字时,被释的词往往是表示某种性质或某种状态的形容词4.这个术语一般是用来注音,但有时也用本字来说明假借字。
5.所谓拗救,就是指在律诗的一个句子中,本该用平声的地方却用了仄声,然后在本句或对句的适当位置,把该用仄声的字改用平声,以便补救。
1.按照韵尾的不同,古韵学家把韵分为三大类。
一类是以鼻辅音[-m]、[-n]、[-ŋ]收尾的,叫“阳声韵”;2.我国传统语音学按发音部位的不同,把声母分为:唇音、舌音、齿音、牙音、喉音五类,这就是音韵学上所谓的“五音”。
3.一般用在动词或形容词后面。
使用“貌”字时,被释的词往往是表示某种性质或某种状态的形容词4.正义:即注解经书而得义之正。
唐人称“义疏”为“正义”,义疏即取疏通经注意义的意思。
5.所谓“粘”,指一首律诗中相邻两联的上联对句和下联出句的第二字平仄必须相同。
所谓“对”,是指一首律诗中同一联内的出句和对句的平仄必须相反。
1.按照韵尾的不同,古韵学家把韵分为三大类。
一类是以清塞音[-p]、[-t]、[-k]收尾的,叫:“入声韵”。
2.叠韵:双声是古汉语中常见的语音现象,就是两个字的韵相同。
3.七音:宋元等韵学家从舌音中又分出半舌音,从齿音中又分出半齿音,连同上述“五音”,就构成了音韵学上所谓的“七音”。
