对龙岗壮语7个腭化音声母phj、thj、khj、mj、nj、■j、lj分别与李方桂先生构拟的原始台语声母和标准语声母的对应情况进行比较分析,从而探讨它们各自的演变过程和来源。龙岗壮语腭化音声母的来源主要有三个:一是来源于对应的古浊音声母;二是来源于带先喉塞成分的清声类声母;三是来源于带流音的复辅音声母。 The phonetic consonants phj, thj, khj, mj, nj, jj and lj of Longgang Zhuang language are compared with those of the original Taiwanese consonants and standard consonants respectively formulated by Mr. Li Fanggui to explore their respective Evolution and sources. Longgang Zhuang palatal acoustic initials come from three main sources: one is derived from the corresponding ancient voiced consonants; the second is derived from the composition of the first voiceless consonant consonant; the third is derived from the consonant consonant with a stream of voices.
