本文取《搜神記》的語言和西晉佛經作客觀的比較，作全面的、窮盡式的描寫，目的不在於考證《搜神記》的時代問題，而在於透過這兩個表示相對概念的常用字，了解這兩種時代相近的材料當中的具體狀況，觀察它們的異同，以提供漢語史研究的參考。我們可以歸納出「來」字意義上的兩個特性：表時間概念、表空間的活動。晉代漢語的「來」字以前者為主。《搜神記》表現了「來」字作為後綴的強大構詞力，它在構詞上是一個表時間概念的後綴。「去」字的基本用法是作單音節動詞。早期的意義是「離開」，後來演變為「前往」。西晉佛經「去」字出現最多的例子是作單音節動詞，不及物。但「去」字居於後位的複合詞，我們認為已經屬於動補結構，「去」的意義已經虛化，至少已經泛化。所以它能夠自由的和多種動詞相結合。西晉佛經組成複合詞「過去」，表示時間概念，修飾後面的名詞，是最常出現的用語。《搜神記》則無此用語。西晉佛經還有一種《搜神記》所沒有的構詞，就是「去V」的動詞並列式。文末，我們把西晉佛經和《搜神記》「來、去」的語法狀況做成一個對照表，以顯示其中的異同。

This article take SOUSHENJI of Jin Dynasty to compare the Buddhist texts in the area of verb LAI/QU .
