Re-analyzing the reason of unconditional multiple division of MC voiced initials in Jianyang dialect of Northern Min

摘要: 本文分析结果表明：造成今闽北建阳方言全浊声母无条件多分的原因，并非"原始闽语的残存"也非"方言混合"，而是自然音变。建阳方言 全浊声母在发生音变时兼有"弛声"("清音浊流")和"振声"(声带振动)两种浊音类型，这两种类型"清化"和"弱化"的音变方向不一致，且在扩散式音变中"清化"音变被"弱化"音变所阻断，造成音变的残留，最终导致了全浊声母无条件多分的局面。 ABSTRACT: The analysis of this paper shows that: The unconditional multiple division of MC voiced Initials in modern Jianyang Dialect of Northern Min is neither because of the residue of proto Min nor the result of the mixture of multiple dialects, but the result of natural sound change. Given the MC voiced Initials in Jianyang dialect have two different kinds of voiced initials: "slack voice" type and "real voiced" type when the sound change happened, these two kinds of voiced initials have different "devoicing" and "lenition" sound change direction, and they mutually restrict each other in the diffusion sound change.
