表示数目多少或顺序先后的词叫做数词(numeral)。数词与不定式代词很相似，其用法相当于名词与形容词。
数词有两种。表示数目多少的数词叫做基数词(cardinal
numeral)，如
one，ten，fifty-two等。表示顺序先后的数词叫做序数词(ordinal
numeral)，如
first，tenth，fiftieth等。
1)1-12的基数词是：
one
1,
two
2,
three
3,
four
4,
five
5,
six
6,
seven
7,
eight
8,
nine
9,
ten
10,
eleven
11,
twelve
12.
13-19，皆由3-9加后缀-teen构成，即：
thirteen
13,
fourteen
14,
fifteen
15,
sixteen
16,
seventeen
17,
eighteen
18,
nineteen
19.
(注意thirteen，fifteen，eighteen的拼法)
20-90等十位数均由2-9加加后缀-ty构成，即：
twenty
20,
thirty
30,
forty
40,
fifty
50,
sixty
60,
seventy
70,
eighty
80,

21-29由十位数20加个位数1-9构成，中间须有连字符“-”，即：
twenty-one
21,
twenty-two
22,
twenty-three
23,
twenty-four
24,
twenty-five
25,
twenty-six
26,

fifty-three
53,
sixty-
four
64,
seventy-five
75,
eighty-six
86,
ninety-seven
97.
2)百位数由1-9加hundred构成，如包含十位数及个位数，中间用and连接，也可以不用;如只包含个位数，即十位数为零时，则and不可省。如：
a
(one)

(英语中从1100-1900之间的整数常用hundred表示)
3)千位数由1-9加thousand构成，其后的百、十、个位数构成方法同前。如：
a
(one)

1000

2000

英国英语的billion=1

000
000
000，即10的12次方，等于美国英语的trillion。现在英国也有人采用美国用法，故英国计量局认为最好避免使用billion，trillion(美制10的12次方，英制10的15次方)和quadrillion((美制10的15次方，英制10的18次方)。
