English number words include numerals and various words derived from them, as well as a large number of words borrowed from other languages.
Cardinal numbers
Cardinal number
In mathematics, cardinal numbers, or cardinals for short, are a generalization of the natural numbers used to measure the cardinality (size) of sets. The cardinality of a finite set is a natural number: the number of elements in the set. Th ...
s refer to the size of a group. In English, these words are numerals.
If a number is in the range 21 to 99, and the second digit is not zero, the number is typically written as two words separated by a
hyphen
The hyphen is a punctuation mark used to join words and to separate syllables of a single word. The use of hyphens is called hyphenation. ''Son-in-law'' is an example of a hyphenated word. The hyphen is sometimes confused with dashes (figure d ...
.
In English, the
hundred
100 or one hundred (Roman numeral: C) is the natural number following 99 and preceding 101.
In medieval contexts, it may be described as the short hundred or five score in order to differentiate the English and Germanic use of "hundred" to de ...
s are perfectly regular, except that the word ''hundred'' remains in its singular form regardless of the number preceding it.
So too are the thousands, with the number of thousands followed by the word "thousand". For the number one thousand it may be written 1 000 or 1000 or 1,000, for larger numbers they are written for example 10 000 or 10,000 for ease of human reading. The use of the , as a separator is avoided in some languages as it is used for a decimal placement, for example with money. As a result some style guides recommend avoidance of the
comma
The comma is a punctuation mark that appears in several variants in different languages. It has the same shape as an apostrophe or single closing quotation mark () in many typefaces, but it differs from them in being placed on the baseline ...
(,) as a separator and only to use the
period
Period may refer to:
Common uses
* Era, a length or span of time
* Full stop (or period), a punctuation mark
Arts, entertainment, and media
* Period (music), a concept in musical composition
* Periodic sentence (or rhetorical period), a concept ...
(.) as a decimal placement. Thus a half would be written 0.5 in decimal, base ten notation, and fifty thousand as 50 000, and not 50.000 nor 50,000 nor 50000. As the English language has no language academy to make usage correct there is still a wide variety of usage, other languages do have language academies which ruled on these matters, yet their rulings are deprecated by international standards like the SI system or EU recommendations which leads to varied usage.
In American usage, four-digit numbers are often named using multiples of "hundred" and combined with tens and ones: "eleven hundred three", "twelve hundred twenty-five", "forty-seven hundred forty-two", or "ninety-nine hundred ninety-nine." In British usage, this style is common for multiples of 100 between 1,000 and 2,000 (e.g. 1,500 as "fifteen hundred") but not for higher numbers.
Americans may pronounce four-digit numbers with non-zero tens and ones as pairs of two-digit numbers without saying "hundred" and inserting "oh" for zero tens: "twenty-six fifty-nine" or "forty-one oh five". This usage probably evolved from the distinctive usage for years; "nineteen-eighty-one", or from four-digit numbers used in the American telephone numbering system which were originally two letters followed by a number followed by a four-digit number, later by a three-digit number followed by the four-digit number. It is avoided for numbers less than 2500 if the context may mean confusion with time of day: "ten ten" or "twelve oh four".
Intermediate numbers are read differently depending on their use. Their typical naming occurs when the numbers are used for counting. Another way is for when they are used as labels. The second column method is used much more often in
American English
American English, sometimes called United States English or U.S. English, is the set of variety (linguistics), varieties of the English language native to the United States. English is the Languages of the United States, most widely spoken lan ...

British English (BrE, en-GB, or BE) is, according to Lexico, Oxford Dictionaries, "English language, English as used in Great Britain, as distinct from that used elsewhere". More narrowly, it can refer specifically to the English language in ...
. The third column is used in British English but rarely in American English (although the use of the second and third columns is not necessarily directly interchangeable between the two regional variants). In other words, British English and American English can seemingly agree, but it depends on a specific situation (in this example, bus numbers).

, many students are taught, not to use the word ''and'' anywhere in the whole part of a number, so it is not used before the tens and ones. It is instead used as a verbal delimiter when dealing with
compound numbers. Thus, instead of "three hundred and seventy-three," "three hundred seventy-three" would be said. Despite this rule, some Americans use the ''and'' in reading numbers containing tens and ones as an alternative variant.

.
Many people have no direct experience of manipulating numbers this large, and many non-American readers may interpret ''billion'' as 10
12 (even if they are young enough to have been taught otherwise at school); moreover, usage of the "long" billion is standard in some non-English speaking countries. For these reasons, defining the word may be advisable when writing for the public.
The numbers past one trillion in the short scale, in ascending powers of 1000, are as follows: quadrillion, quintillion, sextillion, septillion, octillion, nonillion, decillion, undecillion, duodecillion, tredecillion, quattuordecillion, quindecillion, sexdecillion, septendecillion, octodecillion, novemdecillion and vigintillion (which is 10 to the 63rd power, or a one followed by 63 zeros). The highest number in this series listed in modern dictionaries is centillion, which is 10 to the 303rd power. The interim powers of one thousand between vigintillion and centillion do not have standardized names, nor do any higher powers, but there are many extensions in use. The highest number listed in Robert Munafo's table of such unofficial names is milli-millillion, which was coined as a name for 10 to the 3,000,003rd power.

Other examples are given in the Specialist Numbers.
Negative numbers
The name of a negative number is the name of the corresponding positive number preceded by "minus" or (American English) "negative". Thus −5.2 is "minus five point two" or "negative five point two". For temperatures, North Americans colloquially say "below"—short for "below zero"—so a temperature of −5° is "five below" (in contrast, for example, to "two above" for 2°). This is occasionally used for emphasis when referring to several temperatures or ranges both positive and negative. This is particularly common in Canada where the use of Celsius in weather forecasting means that temperatures can regularly drift above and below zero at certain times of year.

Ordinal numbers such as 21st, 33rd, etc., are formed by combining a ''cardinal'' ten with an ''ordinal'' unit.
Higher ordinals are not often written in words, unless they are round numbers (thousandth, millionth, billionth). They are written with digits and letters as described below. Some rules should be borne in mind.

* If the tens digit of a number is 1, then "th" is written after the number. For example: 13th, 19th, 112th, 9,311th.
* If the tens digit is ''not'' equal to 1, then the following table could be used:
*For example: 2nd, 7th, 20th, 23rd, 52nd, 135th, 301st.
These ordinal abbreviations are actually hybrid contractions of a numeral and a word. 1st is "1" + "st" from "first". Similarly, "nd" is used for "second" and "rd" for "third". In the legal field and in some older publications, the ordinal abbreviation for "second" and "third" is simply "d".
*For example: 42d, 33d, 23d.
NB: "D" still often denotes "second" and "third" in the numeric designations of units in the US armed forces, for example, 533d Squadron, and in legal citations for the second and third series of case reporters.

''Twelve thirty-four'' would be the norm on both sides of the Atlantic for the year 1234. The
years 2000 to 2009 are most often read as
''two thousand'', ''two thousand (and) one'' and the like by both British and American speakers. For years after 2009, ''twenty eleven'', ''twenty fourteen'', etc. are more common, even in years earlier than 2009 BC/BCE. Likewise, the years after 1009 (until 1099) are also read in the same manner (e.g. 1015 is either ''ten fifteen'' or, rarely, ''one thousand fifteen''). Some Britons read years within the 1000s to 9000s BC/BCE in the American manner, that is, 1234 BC is read as ''twelve (hundred and) thirty-four'' BC, while 2400 BC can be read as either ''two thousand four hundred'' or ''twenty four hundred'' BC.
Collective numbers
Collective numbers are numbers that refer to a group of a specific size. Words like "pair" and "dozen" are common in English, though most are formally derived from Greek and Latin numerals, as follows:
Fractions and decimals
Numbers used to denote the denominator of a fraction are known linguistically as "
partitive In linguistics, the partitive is a word, phrase, or case that indicates partialness. Nominal partitives are syntactic constructions, such as "some of the children", and may be classified semantically as either set partitives or entity partitives ba ...
numerals." In spoken English, ordinal numerals and partitive numerals are identical with a few exceptions. Thus "fifth" can mean the element between fourth and sixth, or the fraction created by dividing the unit into five pieces. When used as a partitive numeral, these forms can be pluralized: one seventh, two ''sevenths.'' The sole exceptions to this rule are division by one, two, and sometimes four: "first" and "second" cannot be used for a fraction with a denominator of one or two. Instead, "whole" and "half" (plural "halves") are used. For a fraction with a denominator of four, either "fourth" or "quarter" may be used.
Here are some common English

A fraction (from la, fractus, "broken") represents a part of a whole or, more generally, any number of equal parts. When spoken in everyday English, a fraction describes how many parts of a certain size there are, for example, one-half, eight ...
s, or partitive numerals:
Alternatively, and for greater numbers, one may say for 1/2 "one over two", for 5/8 "five over eight", and so on. This "over" form is also widely used in mathematics.
Fractions together with an integer are read as follows:
*1½ is "one and a half"
*6¼ is "six and a quarter"
*7⅝ is "seven and five eighths"
A space is required between the whole number and the fraction; however, if a special fraction character is used like "½", then the space can be done without, e.g.
* 9 1/2
* 9½

In mathematics, cardinal numbers, or cardinals for short, are a generalization of the natural numbers used to measure the cardinality (size) of sets. The cardinality of a finite set is a natural number: the number of elements in the set. Th ...
, then "and", then another cardinal number followed by an indication of the significance of the second cardinal number (mainly U.S.); or as a cardinal number, followed by "point", and then by the digits of the fractional part. The indication of significance takes the form of the denominator of the fraction indicating division by the smallest power of ten larger than the second cardinal. This is modified when the first cardinal is zero, in which case neither the zero nor the "and" is pronounced, but the zero is optional in the "point" form of the fraction.
Some American and Canadian schools teach students to pronounce decimaly written fractions (for example, ''.5'') as though they were longhand fractions (''five tenths''), such as ''thirteen and seven tenths'' for 13.7. This formality is often dropped in common speech and is steadily disappearing in instruction in mathematics and science as well as in international American schools. In the U.K., and among most North Americans, 13.7 would be read ''thirteen point seven''.
For example:
*0.002 is "point zero zero two", "point oh oh two", "nought point zero zero two", etc.; or "two thousandths" (U.S., occasionally)
*3.1416 is "three point one four one six"
*99.3 is "ninety-nine point three"; or "ninety-nine and three tenths" (U.S., occasionally).
In English the decimal point was originally printed in the center of the line (0·002), but with the advent of the typewriter it was placed at the bottom of the line, so that a single key could be used as a full stop/period and as a decimal point. In many non-English languages a full-stop/period at the bottom of the line is used as a thousands separator with a comma being used as the decimal point.
Whether or not digits or words are used
With few exceptions, most grammatical texts rule that the numbers zero to nine inclusive should be "written out" – instead of "1" and "2", one would write "one" and "two".

::"That is one hundred and twenty-five oranges." (British English)
::"That is one hundred twenty-five oranges." (US-American English)
::"That is 125 oranges." (Preferred)
Numbers at the beginning of a sentence should also be written out, or the sentence rephrased.
The above rules are not always followed. In literature, larger numbers might be spelled out. On the other hand, digits might be more commonly used in technical or financial articles, where many figures are discussed. In particular, the two different forms should not be used for figures that serve the same purpose; for example, it is inelegant to write, ''"Between day twelve and day 15 of the study, the population doubled."''
Empty numbers
Colloquial English's small vocabulary of empty numbers can be employed when there is uncertainty as to the precise number to use, but it is desirable to define a general range: specifically, the terms "umpteen", "umpty", and "
zillion
Many languages have words expressing indefinite and fictitious numbers—inexact terms of indefinite size, used for comic effect, for exaggeration, as placeholder names, or when precision is unnecessary or undesirable. One technical term for such ...
". These are derived etymologically from the range affixes:
* "-teen" (designating the range as being between 13 and 19 inclusive)
* "-ty" (designating the range as being between 20 and 90 inclusive)
* "-illion" (designating the range as being above 1,000,000; or, more generally, as being extremely large).
The prefix "ump-" is added to the first two suffixes to produce the empty numbers "umpteen" and "umpty": it is of uncertain origin. A noticeable absence of an empty number is in the hundreds range.
Usage of empty numbers:
* The word "umpteen" may be used as an adjective, as in "I had to go to umpteen stores to find shoes that fit." It can also be used to modify a larger number, usually "million", as in "Umpteen million people watched the show; but they still cancelled it."
* "Umpty" is not in common usage. It can appear in the form "umpty-one" (paralleling the usage in such numbers as "twenty-one"), as in "There are umpty-one ways to do it wrong." "Umpty-ump" is also heard, though "ump" is never used by itself.
* The word "zillion" may be used as an adjective, modifying a noun. The noun phrase normally contains the indefinite article "a", as in "There must be a zillion pages on the World Wide Web."
* The plural "zillions" designates a number indefinitely larger than "millions" or "billions". In this case, the construction is parallel to the one for "millions" or "billions", with the number used as a plural count noun, followed by a prepositional phrase with "of", as in "There are zillions of grains of sand on the beaches of the world."
* Empty numbers are sometimes made up, with obvious meaning: "squillions" is obviously an empty, but very large, number; a "squintillionth" would be a very small number.
* Some empty numbers may be modified by actual numbers, such as "four zillion", and are used for jest, exaggeration, or to relate abstractly to actual numbers.
* Empty numbers are colloquial, and primarily used in oral speech or informal contexts. They are inappropriate in formal or scholarly usage.
