汉语借词中,单音节外来词只占一小部分。但它们音节短,语法功能强,出现频率高。本文以酷(cool)、嗨(high)、秀(show)、的(taxi)、吧(bar)、站(jam)和波(ball)等词为例,就其类型、功能与汉化等方面分析单音节外来词的特点。文章提出,单音化是汉语同化外来词的一条途径,为纠正将外来词与语素混为一谈的偏颇,本文建议在汉语里建立“外来语素”概念。 Chinese loanwords, monosyllabic loan words only a small part. However, they have short syllables, strong grammatical functions and high frequency of occurrence. In this paper, we use the terms cool, high, show, taxi, bar, jam and ball as examples to discuss their types, functions and localization Analysis of monosyllabic foreign words. The paper proposes that mono-tonalization is one way to assimilate foreign words in Chinese. To correct the biased mixing of foreign words and morphemes, this paper proposes to establish the concept of “foreign morphemes ” in Chinese.
