泉州方言的虚词“咧”可以标记完成体、进行体和持续体。它与明清泉腔戏文8种相关格式中的“处”平行对应,这8种格式的消长兴替表明,体标记“咧”源于介词结构“在+只/许处”。但“咧”并不是介词“在”的进一步虚化,而是充当介词宾语的处所词“处”的虚化。大约在清末民国时期,“处”的虚化导致了语音演变,最终形成了现代泉州方言体标记“咧”。 Quanzhou dialect function words “blanket ” can mark the completion of body, body and continuum. It parallels the “Department” of 8 kinds of related formats in the Quanjuquan opera. The eight kinds of formats show that the signs and marks of the body are derived from the prepositional structure “ ”. However, “blanket” is not a precondition of “preposition”, but a place of preposition “s”. About the period of the late Qing and Republican China, the deficiency of “Department ” led to the evolution of speech and finally formed the label of modern Quanzhou dialect “blanket ”.
