上海市奉贤区庄行镇方言中有五个“时、体”结合的复合时态,本文讨论它们的时体助词由动词“在”和方所介词逐渐语法化变来的过程。此现象在传教士的《上海方言教程》中也有记录,但在市区中已经消失;郊区奉贤由于发展比较慢,至今仍保留此现象。复合时态在有些其他吴语方言甚至非吴语方言中也有存在。 In the dialect of Zhuanghang Town, Fengxian District, Shanghai, there are five “tense” combination tense, this paper discusses the process that their tense modifiers are changed from verb “in ” and square preposition. . This phenomenon is also recorded in the missionary’s “Shanghai Dialect Tutorial”, but it has disappeared in the urban areas.
