一到三十的序数词

1st = first

2nd = second

3rd=third

4th=fourth

5th=fifth

6th=sixth

7th=seventh

8th=eighth

9th=ninth

10th=tenth

11th=eleventh

12th=twelfth

13th=thirteenth

14th=fourteenth

15th=fifteenth

16th=sixteenth

17th=seventeenth

18th=eighteenth

19th=nineteenth

20th=twentieth

21st=twenty-firstu

22nd=twenty-second

23rd=twenty-third

24th=twenty-fourth

25th=twenty-fifth

26th=twenty-sixth

27th=twenty-seventh

28th=twenty-eighth

29th=twenty-ninth

30th=thirtieth

说明

1、许多序数词是由相应的基数词后加th构成的，如：four / fourth，six / sixth，ten / tenth，sixteen / sixteenth，但是nine变为序数词是ninth，而不是nineth。

2、twentieth, thirtieth, fortieth等表示整十的序数词，由相应的基数词将词尾y改为ie，再加th构成。

3、first, second, third通常可缩写为1st, 2nd, 3rd。凡是以th结尾的序数词可缩写为“基数词＋th”：4th, 5th, 9th, 11th, 60th, 128th等。

4、非整十的多位数，将个位数变成序数词即可：twenty-first(第21)，thirty-sixth(第36)，ninety-ninth(第99)，three hundred and sixty-fifth(第365)等。
