通感,又称“感觉挪移”、“联觉”、“移觉”,它本是一种心理现象。“通感”语言现象就是对这种心理现象的文字描述。有的词语本来用于表示某种感觉,后来常常被用来描述其它种类的感觉,如此年深月久地使用便逐渐获得了表示其它感觉的意义,最终形成固定的新义。 Synaesthesia, also known as “feeling diversion”, “linked awareness”, “transfer feeling”, it is a psychological phenomenon. The “sense of sensation” linguistic phenomenon is a written description of this psychological phenomenon. Some words were originally used to express certain feelings, and were later often used to describe other kinds of feelings. Using them for years and months, they gradually acquired the meaning of expressing other feelings and finally formed a fixed new meaning.
