时间词“后来”的形成经历了两个阶段。先由句法层面的同形短语固化为一个普通名词,进而在隐喻引申和句法功能扩张等因素的驱动下由普通名词发展为时间词。在历时发展中,时间词“后来”的词义也经历了一次大的转变,即由指示未来时间转向指示过去时间。 The formation of the time word “later ” has gone through two stages. First, the homomorphic phrase at the syntactic level is solidified into a common noun, and then the common noun is developed into a time word driven by factors such as the extension of the metaphor and the expansion of the syntactic function. In the diachronic development, the meaning of the time word “later ” has also undergone a major shift from directing the future time to indicating the past time.
