4-10通常在词尾加-th:four→fourth(4th),five→fifth(5th),six→sixth(6th),seven→seventh(7th),eight→eighth(8th),nine→ninth(9th),ten→tenth(10th);
以ve结尾的基数词,变ve为f加-th:twelve→twelfth(12th);
以y结尾的整十数,变y为ie加-th:twenty→twentieth(20th);
几十几的数词变序数词,仅将个位改为序数词:twenty-one→twenty-first(21st),twenty-two→twenty-second(22nd),twenty-three→twenty-third(23rd);
部分基数词直接加-th:fifteen→fifteenth(15th),eighteen→eighteenth(18th)。
