カテゴリーを形成する2種のベクトル : 「真(ま) +色彩語彙」表現の分析

Japanese “ma" is a prefix to express that the topic is a true member of the category classified by the following word. This means that the prefix “ma" represents the speaker's intention to categorize the thing in sight，and it functions as a vector to form a category in cognition. This paper examines the compounds of “ma" and color terms to clarify the system of categorization. Though the prefix “ma" always indicates that the colors in sight are true members of categories，the compounds "ma-color term" do not always refer to the same colors. They sometimes refer to the prototypical colors，and sometimes refer to some colors out of the ordinary color categories of that color term. Different meanings of the compounds“ma-color term" show that two kinds of vectors are in effect in forming categories. A vector to get close to the prototype of the category due to similarity and another vector to get away from some other category due to contrastive difference.
