英文順位中簡寫的問題

「第一」簡寫為 1『st』;「第二」簡寫為 2『nd』;「第三」簡寫為 3『rd』;「第四」之後簡寫為 oo『th』;那「第二十一」該簡寫為21『nd』還是21『th』呢?

Update:

為何這裡用「21th」

Update 2:

而,這裡又用「21st」呢?

    這個東西叫做"序數",當形容詞(adj)時前面加the,當副詞(adv)時不加

    第一的英文是first,所以簡稱1st

    第二是second

    第三是third

    第四到第二十的字尾都是th,所以都加th

    第二十一的英文是twenty-first,所以是21st

    以下是序數的英文

    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-first 22nd twenty-second 23rd twenty-third ......

    30th thirtieth 40th fortieth 50th fiftieth 60th sixtieth

    70th seventieth 80th eightieth 90th ninetieth

    100th one hundredth

    101st one hundred and first .......

    500th five hundredth

    1000th one thousandth

    序數指的是"第幾"

    你補充的第一個是"日期"

    用法不一樣...

    21 寫成 21st. 22 為 22nd, 23 = 23rd, 24 = 24th, 30.... 一樣的道理,不再多寫了
