本文對彝緬語系裡的“入聲”音節（字尾有塞音），特別是在平常與古全濁聲母有關係的“低音處”中表現送氣全清塞音聲母那一類的字（例如“六”），提議一個新的，同時也希望是一個更簡單的來源。從東亞各種語系的證據裡可以更清楚暸解到，筆者所提議的語音發展過程其實在漢藏語系地區早已到處存在。

This paper proposes a new and, hopefully, simpler explanation for the historical development of syllables with final stops in Yipo-Burmic (Lolo-Burmese) languages, particularly in regard to syllables such as 'six,' which show a voiceless, aspirated stop initial in the ' lower register,' a tonal category often associated with voiced proto-initials. Evidence cited from several other East Asian linguistic phyla suggests that the development which the author proposes for Yipo-Burmic is already widely seen in this area.
