本文根據石陂閩語的新資料推斷上古音中有g和γ的不同,上古匣母字可以分成兩類,一類和群母合而為一,上古音是g,現在石陂仍有讀g-的現象;另一類匣母字和喻三合而為一,上古音是γ,石陂則有讀ɦ-的痕跡。羅杰瑞(Jerry Norman)的古閩語系統中有g、gh、-g、h、y等五個聲母,可以簡化為g和h兩種。
According to the new material discovered in Shibo (石陂), a Northern Min dialect, this paper suggests that there were g and ɣ initials in Archaic Chinese. The characters that belong to the xia initial (匣) in Archaic Chinese may be divided into two groups. One group, which originally combined with characters of the qun initial (羣), originated from Archaic Chinese g- and is preserved as g-in Shibei; the other group, which originally combined with characters of the yu initial (喻三), originated from Archaic Chinese ɣ- and is preserved as ɦ- in Shibei. Jerry Norman reconstructed five distinctive initials in his proto-Min system, namely, g, gh, -g, h, and ɣ, which could be reduced to two, namely, g and ɣ.
