先秦至六朝的汉语文献中有这样一种随机性的连读音变:非去声字位于s声字前而变为去声,或非s声字位于去声字后而变为s声;或去声字位于s声字前而变为非去声,或s声字位于去声字后而变为非s声。其中的作用因素是音素s。这种古汉语文献中的连读音变现象支持汉语去声源于~*-s尾的理论。 In the Chinese literature from the Qin Dynasty to the Six Dynasties, there was such a random variation of continuous reading that the non-silent words became syllable before s words or s-words became s-syllable after syllable words or The syllables become non-syllable before the syllables, or s syllables become syllables after syllables. One of the factors is phoneme s. In this ancient Chinese literature, the phenomenon of continual phonetic transcription supports the theory that Chinese speech is originated from ~ * -s tail.
