在日语的习惯中,对事物进行数量统计时,原则上通常不会单独使用数词,更多的是伴随着例如“一支铅笔”、“三只猫”这样的量词接续。这种直接附在数词后面的量词接续在日语中被称为“助数词”。日语当中此类词非常发达,不完全统计大约有五百个。而且,助数词通常会因为前面数词的发音而影响到自身的读音,发声音变或者连浊的现象。 In the Japanese custom, when counting the number of things, in principle, the numerals are not usually used alone, more often accompanied by measurement words such as “a pencil ” and “three cats ”. This type of quantifier, which is attached directly after the numeral, is called “auxiliary word ” in Japanese. Such words are well developed in Japanese, incomplete statistics about five hundred. Moreover, auxiliary digits often affect their pronunciation, phonation, or even voicedness due to the pronunciation of the preceding numeral.
