上古漢語常見用「孰與」連接兩比較項供受話人比較、選擇。而過去對於「孰與」這一結構的來源、表達語義都還有可待商榷處。本文一方面從疑問代詞「孰」本身的特性以及說話人的認知機制解釋「孰與」結構的產生;另一方面考察「孰與」的語義及使用特性,並從語體的角度解釋了何以過去學者多認為「孰與」可以表達反詰,卻無法準確判斷說話人的意向是選擇「孰與」的前項還是後項,這和這類「孰與」所在的議論語體有關。文中區分了三種「孰與」的使用情境:無知之問、引導之問及有問無答的引導之問。本研究進一步探索「孰與」結構形成的可能性,也更為清楚地描繪了「孰與」的使用特性,並從旁證明引入語體參數對於語法研究的重要性。
"Shuyu" (孰與) is a commonly used conversation structure in Archaic Chinese. It was used when the speaker provides two choices for the addressee to compare and select. However, the origin and sematic expression of the structure still have much room for discussion. This paper aims to explain the formation of the structure of "Shuyu," through the characteristic of the pronoun "shu" used in questioning and the cognitive mechanism of the speaker. On the other hand, it also seeks to discuss the sematic and usage features of "shuyu", and from the perspective of linguistic register, explain why even though past discussions believe that "shuyu" can be used to express a rhetorical question, but yet cannot determine whether the speaker's intent is skewed towards the first or second choice. This is due to the argumentative style of the question when "shuyu" is used. Three usage scenarios of "Shuyu" is listed in this paper: Questioning when the speaker is clueless, questioning as a motive leading to further discussion and questioning without the intent of an answer. This research further explores possibilities of how the structure of "shuyu" has been formed, clearly describing its application features, and highlighting the importance of referring to linguistic register during grammatical research.
