促音是日语语音中的特有现象,一般出现在多音节词中。其中许多成对词在词义方面相同,以促音与非促音两种形式并存,形成了日语词汇中的一个特色。考察结果表明,促音词同非促音词相比,在使用范围、构词、词义以及活用形转化等方面,前者有着明显的限定作用。 Prompt sound is a unique phenomenon in Japanese speech, and is commonly found in polysyllabic words. Many pairs of words are synonymous in terms of meaning and form a distinctive feature of the Japanese vocabulary in the form of sound reinforcement and non-sound reinforcement. The result of the investigation shows that the former has obvious limitation in terms of scope of use, word formation, meaning and the transformation of utilization form compared with non-tone word.
