英语序数词第1-19除first,second与third有特殊形式外,其余均由基数词加字尾-th构成(注意第五、第八、第九、第十二的特殊拼写)。现将第1-19的序数词列出如下。用阿拉伯数字表示序数时,要在阿拉伯数字的后面加上序数词的词尾即可。
first 1st
second 2nd
third 3rd
fourth 4th
fifth 5th (fif加th)
sixth 6th
seventh 7th
eighth 8th(后只加h)
ninth 9th(nin加th)
tenth 10th
eleventh 11th
twelfth 12th (twelf加th)
thirteenth 13th
fourteenth 14th
fifteenth 15th
sixteenth 16th
seventeenth 17th
eighteenth 18th
nineteenth 19th。
整十位数的序数词的构成方法是:先将十位数的基数词的字尾ty中的y变为i,然后加字尾-eth。如:
twentieth 20th
thirtieth 30th
fortieth 40th
十位数的序数词如包含1-9的个位数时,十位数用基数词表示,个位数用序数词表示,中间须有连字符“-”。
如:
twenty-first 21st
thirty-second 32nd
forty-fourth 44th
eighty-seventh 87th
百、千、百万等的序数词由hundred,thousand、million等加-th,前面加有关的基数词构成。如:
(one) hundredth 100th
(one) thousandth 100th
ten thousandth 10 000th
(one) hundred thousandth 100 000th
(one) millionth 1 000 000th
ten millionth 10 000 000th
(one) hundred millionth 100 000 000th
(one) billionth 1 000 000 000th
注意序数词hundredth,thousandth, millionth, billionth之前的“一”只可用one,不可用a。
这些多位数序数词的后位数如包含1-9时,后位数用序数词,前位数用基数词,中间出现零时,须用and连接。如:
two hundred and first 201st
three thousand two hundred (and) twenty-first 3221st
