Ordinal numbers in Russian. Numerals in English Rules for the formation of numerals in English

home / Love

Numerals denote the number of objects, and we encounter quantities every day. You need to buy 3 kilograms of sugar, two kilograms of potatoes, and the third eggplant is better than the second, give me a fifth piece of pie and one sweet water... See? It is simply impossible to say these sentences without numerals. Today we will learn ordinal numbers in English (Ordinal Numerals) , We will give examples and subtleties of their use.

Ordinal numbers are a class of numeral names that denote the order of objects when counting. Ordinal numbers in English answer the question Which?“which?”, “which?”. To make it easier for beginning students to distinguish the types of numerals in English, they need to be asked a question.

For example:

  • The eleventh frog - The eleventh toad;
  • The fourteenth pen - The fourteenth pen;
  • The second ball - Second ball;
  • The fifth pupil - The fifth student.

Ordinal numbers are formed in English by adding the suffix “ th» to the corresponding ordinal number. The exception is such ordinal numbers as: the first, the second, the third, they are not formed according to the rules and need to be remembered. All ordinal numbers must be preceded by a definite, since English ordinal numbers are a definition of a specific noun.

When writing decimal ordinal numbers, for example, 32, 45, 76 or 93, a hyphen is placed between the words, and a suffix is ​​placed only in the second word, while the first remains unchanged:

  • 43 => forty-three -> The forty-third
  • 25 => twenty-five -> The twenty-fifth
  • 27 => twenty-seven -> The twenty-seventh
  • 49 => forty-nine -> The forty-ninth, etc.

30 Thirty The Thirtieth
40 Forty The Fortieth
50 Fifty The Fiftyeth
60 Sixty The Sixtieth

Examples

  • Thirty cakes were baked for this holiday but I don’t understand where is the thirtieth? — Thirty cakes were baked for this holiday, but I don’t understand where the thirtieth is?
  • Seventy balls were of blue color while the fiftieth was an extraordinary one – of light blue and a bit of yellow color! — Seventy balls were blue, while the fifty was extraordinary - light blue with a hint of yellow!
  • The eighty participants were so beautiful I couldn’t stop but looking at them but the eightieth was the most beautiful one! — The eighty participants were so beautiful that I could not take my eyes off them, but the eightieth participant was the most beautiful!

Notice how hundreds, thousands and millions are formed:

  • 100=> one hundred => The hundredth
  • 1000 => one thousand => The thousandth
  • 1,000,000 => one million => The millionth.

On a note! Remember that when we form several hundreds, thousands or millions, we add one more word:

  • 700 => seven hundred => The seven hundredth
  • 900 => nine hundred => The nine hundredth
  • 300,000 => three hundred thousand => The three hundred thousandth
  • 500 000 => five hundred thousand => The five hundred thousandth

Examples:

  • Four hundred thousand tons of sand were needed for this work. — 400,000 tons of sand were needed for this work.
  • The nine hundredth participant denied to be present. — The nine hundredth participant refused to be present.
  • Five hundred thousandth liter of juice was bad. — The five hundred thousandth liter of juice was bad.

Hundreds, thousands and millions: features of use

The first and most important rule: when using hundred, thousand and million, we use the following words in the singular:

  • Three hundred - three hundred
  • Five hundred - five hundred
  • Thirty thousand - thirty thousand
  • Seventy thousand - seventy thousand
  • Nine million - nine million
  • Forty million - forty million.

Reference: if we talk about the number of animate or inanimate objects in thousands, hundreds and millions, we use plural numerals.

  • Hundreds of animals - hundreds of animals
  • Millions of pieces - millions of particles
  • Thousands of barrels - thousands of barrels.

Examples:

  • Millions of pieces of gold were needed to make this constructions. “To make these structures, millions of gold particles were needed.
  • Thousands of animals will migrate in warm countries to spend there several weeks. — Thousands of animals will migrate to warmer climes to spend several months here.
  • Hundreds of flowers were bought to make this festival amazing! - Hundreds of flowers were bought to make this holiday amazing!

Let's sum it up

Ordinal numbers in English are formed from cardinal numbers. Tens, hundreds, thousands and millions have their own educational characteristics, and in each group you can find exceptions. As we know, there are no rules for exceptions; they cannot be explained. All you can do is learn them, and by heart. Then your speech will be correct and pleasing to the ears.

Remember: a person who speaks with errors creates an unpleasant impression, especially if you are talking to the person for the first time. and someone whose speech is smooth and competent creates the impression of an intelligent, educated and well-read interlocutor.

Cardinal numbers determine the number of objects/topics/people, etc., that are discussed in a sentence. As you already understood, “cardinal numerals” are used with countable nouns (subjects and objects that can be counted):

  • two envelopes - two envelopes;
  • four paws - four paws;
  • a thousand reasons - a thousand reasons.

Cardinal numbers are divided into three groups:

1.Simple

Prime numbers include numbers from 1 to 12 inclusive, since they consist of one morpheme, the root of a word: one, eleven, five, etc.

2. Derived

Derivatives include numbers from 13 to 19. To form them, you need to add the suffix “teen” to the simple numeral (or its modified base): eighteen, seventeen, sixteen.

There are two types of stress in these numerals: one falls on the first syllable, the other on the suffix “teen”.

3. Compound

Composite numbers include numbers denoting tens (including in combination with units), starting from 20. When formed, the basis of a simple number is preserved or modified. Up to a hundred, the suffix “-ty” is added to the word: ninety, sixty-one, twenty-three, eighty.

When forming some derivatives and composite cardinal numerals, the basis of the simple numeral changes:

  • three - thirteen, thirty;
  • five - fifteen, fifty;
  • two - twenty;
  • four - fourteen, forty.

Ordinal numerals

Ordinal numbers denote what an object is among many others: fifth, tenth, etc. Most ordinal numbers are formed by adding the suffix “-th” to the cardinal number:

  • seven - seventh;
  • twenty-eight - twenty-eighth;
  • fifteen - fifteenth;
  • seventy-four - seventy-fourth;
  • four hundred (and) twenty - four hundred twentieth.

Note: “-y” at the end of a numeral is changed to “-ie”, after which “-th” is added.

Exceptions or first 3 ordinal numbers

The first three cardinal numbers completely change the root when forming ordinal numbers:

  • one - first ;
  • two - second ;
  • three - third;
  • twenty-one - twenty-first;
  • forty-two - forty-second;
  • thirty-three - thirty-third.

Exercises to practice English numerals

Now that we have become familiar with the new ones and remembered the numbers in English known from our school years, it’s time to consolidate and test our knowledge with exercises. Select one of the learning mode options in the module at the bottom right (selection, memorization, test, flashcards, spelling) and practice both writing and pronunciation.

Functions in a sentence

The numeral, as an independent part of speech, can play different roles in a sentence:

Subject

1998 is a year that he will always remember. - 1998 is a year that he will remember forever.

5 means a number of your good marks for the previous week. - 5 - the number of your positive ratings over the past week.

Addition

If you add one more important detail, we will be more likely to find the place. - If you add one important detail, it will be much easier for us to find this place.

Divide 10 into 5 equal parts and you have 2 as the result. - Dividing 10 into 5 equal parts, you get 2.

Definition

He is leaving for a three-days journey. - He is going on a three-day trip.

She has only 10 minutes to finish her task. - She only has 10 minutes left to solve the problem.

Predicative

His lucky number today is 10. - For today, his lucky number is 10.

Fifty plus thirty-six is ​​86. - If you add thirty-six to fifty, you get 86.

Features of the use of hundred, thousand, million, billion

The numerals “hundred, thousand, million, billion” in the meaning of a precisely defined quantity do not require adding endings:

  • 157 - a hundred (and) fifty-seven;
  • 2380 - two thousand three hundred (and) eighty.

*and is used in British English to link a higher place number with a lower place number, but is omitted in American English.

But if we are talking about them in the meaning of a set, and not a specific number, the situation changes completely; it is necessary to add the ending “-s”:

  • thousands of workers - thousands of workers;
  • hundreds of factories - hundreds of factories.

Reading fractions

In an ordinary (“improper”) fraction with non-integer numbers, the numerator is read as a cardinal number, and the denominator as an ordinal number:

  • ⅓ - one-third;
  • ⅛ - one-eighth.

If the numerator is greater than one, you need to add “-s” to the denominator, already expressed as an ordinal number:

  • 2/9 - two-ninths;
  • 3/11 - three-elevenths.

However, fractions referring to half (“a half”) or a quarter (“a quarter”) are more correctly expressed through the indefinite article or cardinal number:

  • 665... - double six five (two sixes, five);
  • 444… - ​​triple four (three fours).

Reading dates

Reading dates is often simplified: a four-digit number is divided into two two-digit numbers, which are read separately. A full pronunciation is also possible, similar to the Russian language, but it is becoming less and less common:

  • 1786 - seventeen eighty-six / one thousand seven hundred (and) eighty-six;
  • 1580 - fifteen eighty / one thousand five hundred (and) eighty

In the sentence, the year is indicated by a cardinal number, not an ordinal number (there will be no “-th” at the end):

  • He was born in nineteen thirty-six. - He was born in 1936.

If we are talking not about one year, but about a decade (50s, 80s, 90s), you need to add “-s”:

  • In early seventies the Scorpions were popular among young people. - In the early 70s, Scorpions were popular among young people.

Reading money amounts

Reading monetary amounts has a nuance: in the range from 1000 to 10,000, money is calculated in hundreds (the number is divided by one hundred and the word “hundred” is added):

  • $1200 - twelve hundred dollars;
  • $5478 - fifty-four hundred (and) seventy-eight dollars

In other cases, we read it as is:

  • $11000 - eleven thousand dollars;
  • $348 - three hundred (and) forty-eight dollars.

Reading zero

Zero in telephone numbers, calendar years, and in any colloquial speech is read as the letter ‘o’ [əu]. However, in mathematics, zero, which denotes a separate and unrelated number, is read as "zero". The obsolete word “nought”, literally meaning “nothing,” has a similar meaning.

Afterword

The topic of ordinal and cardinal numbers in the English language, like any question that is not difficult in the usual sense, contains many details that you need to remember in order not only to feel freer in expressing thoughts and ideas, but also to understand the native speaker’s speech without problems and unnecessary guesswork .

In English, as in Russian, there are two types of numerals, ordinal (ordinal) and quantitative (cardinal).
First, let's clarify the difference between ordinal and cardinal numbers. In essence, their names speak for themselves.

  • Ordinal numbers indicate the order of objects. Answer the question Which? - Which?
  • As for cardinal numbers, they denote the number of objects and answer the question How many? - How many?

Cardinal numbers are one, two, three, ten, twenty (one, two, three, ten, twenty).
Ordinal - the first, the second, the third, the tenth, the twentieth (first, second, third, tenth, twentieth) Numerals of the English language

Cardinal numbers

So, let's take a closer look at cardinal numerals in English.

Numbers from 1 to 12 are called prime numbers.

Table: Numerals in English with pronunciation

Numerals from 13 to 19 are derived. Formed using the suffix - teen. For example, seven+teen gets seventeen, six+teen gets sixteen. In such numerals as 13, 15,18 there are some exceptions.

Derived numerals are also numerals that denote the tens 20, 30, 40, 50, etc. They are formed using the suffix - ty. However, there are some nuances here that need to be remembered.

Compound numerals are called numerals that denote tens with ones, starting with 21 (twenty-one). They are written with a hyphen. Thus, numbers from 21 to 99 are written with a hyphen.

Hundreds in English are used with cardinal numbers: one hundred-[ˈhʌndrəd], two hundred, three hundred (one hundred, two hundred, three hundred).
Learning numbers in English

Ordinals

Firstly, first, second, third, fifth - these ordinal numbers should simply be remembered, since they represent an exception.

The

The general rule by which ordinal numbers are formed: using the definite article the, and it is also necessary to add the ending to the cardinal number - th.

A few important points to remember:

  • Numerals like twenty, thirty, y goes into i, is added e and only after that we add the standard th.
  • Compound numerals like twenty-one (twenty-one), only one changes, twenty remains unchanged. One goes into ordinal first. In such cases, the article is not needed.

100,000 a (one) hundred thousand a (one) hundred thousandth
1,000,000 a (one) million a (one) millionth
2,000,000 two million two millionth

Formation of cardinal numbers

1. Cardinal numbers from 13 to 19 inclusive are formed by adding the suffix -teen to the corresponding names of the units of the first ten: four - fourteen, seven - seventeen.

Note. Numerals with the suffix -teen have two stresses ("four"teen, "fif"teen, etc.), with the stress on the last syllable being stronger than on the first. When these numerals are used with nouns, the stress falls on the first syllable, and the second syllable becomes unstressed: "fourteen" pens, "fifteen" pencils.

2. The names of cardinal numbers denoting tens are formed by adding the suffix -ty to the names of units: six - sixty, seven - seventy.

Some numerals are formed with the following deviations from the general rule:

Two - twelve - twenty
three - thirteen - thirty
five - fifteen - fifty
eight - eighteen - eighty

The numeral forty differs in spelling from four - fourteen.

3. Tens and ones are formed in the same way as in Russian:

21 - twenty-one; 48 - forty-eight

4. When denoting cardinal numbers, the digits of multi-digit numbers are separated by a comma: 7,000; 5,550,000.

5. Between hundreds (or thousands and millions) and the following tens (or units, if there are no tens) in any category, the union and is always placed:

246 - two hundred and forty-six; 206 - two hundred and six
5,050 - five thousand and fifty; 5,005 - five thousand and five
3,525,250 - three million five hundred and twenty-five thousand two hundred and fifty

6. Numerals 100; 1,000; 1,000,000 is used with the indefinite article a or the numeral one

100 - a hundred / one hundred
1,002 - a thousand and two / one thousand and two

7. The numerals hundred, thousand, million do not accept the ending -s in the plural:
three hundred
four thousand
five million
3,005,240 - three million five thousand two hundred and forty

Note. The numerals hundred, thousand and million become nouns and take an ending if they are used to denote an indefinite number of hundreds, thousands or millions. In this case, they are followed by a noun with the preposition of.

Thousands of workers were streaming out of the plants. - Thousands of workers left the factories in streams.

8. The noun that follows the numeral is used without a preposition and corresponds in Russian to a noun in the genitive case:

Three thousand books - three thousand books
ten students - ten students

Formation of ordinal numbers:

1. Ordinal numbers are formed by adding the suffix -th to cardinal numbers:

Four - fourth
thirteen - thirteenth
seven - seventh
fifteen - fifteenth

The formation of the first three numerals is an exception to this rule:

One-first
two - second
three - third

When forming ordinal numbers fifth - fifth and twelfth - twelfth, the letter v in the names of cardinal numbers (five, twelve) changes to f and the letter e is omitted; in the numeral eight the letter t is dropped, and in the numeral nine the letter e is omitted:

Five-fifth
twelve - twelfth
eight-eighth
nine - ninth

When forming ordinal numbers denoting tens, starting from 20, the final letter y changes to i and e is added before the suffix -th to indicate an additional sound [i]:

Twenty - twentieth
thirty-thirtieth

2. When forming composite ordinal numbers, consisting of two or more numbers, only the last number takes the form of an ordinal number, and the preceding numbers are expressed as cardinal numbers, just as in the Russian language:

Twenty-third - twenty-third
five hundredth - five hundredth
eighty-seventh - eighty-seventh

Nouns identified by an ordinal number are used with a definite article. The article is preserved before the ordinal number, even if the noun is not expressed, but the person is implied.

The first law of motion has the idea of ​​motion and the idea of ​​force. - The first law of motion contains the concept of motion and the concept of force.
The second basket was the same size as the first. - The second basket was the same size as the first.

Note. The use of the indefinite article with an ordinal numeral gives the ordinal numeral an additional meaning corresponding to Russian one more:

Under certain circumstances, a second electron may enter the outer orbit. - Under some circumstances, a second (another) electron may enter the outer orbit.

SOME FEATURES OF THE USE OF NUMERALS IN THE ENGLISH LANGUAGE COMPARED TO THE RUSSIAN LANGUAGE

In English, when designating the number of pages, chapters, parts of books, classrooms, houses, trams, etc. Cardinal numbers are usually used. In this case, the cardinal number follows the noun it defines, and the noun is used without an article: chapter one - chapter of the chapter; part two - part two; lesson three - lesson three; page fifteen - page fifteen.

Open your books at page 23 (twenty three). - Open the books to page 23 (on page 23).
Read paragraph 5 (five). - Read the fifth paragraph.
Figure 6 (six) shows an apparatus for counting the number of alpha-particles. - The sixth picture (Figure 6) shows an apparatus for counting the number of alpha particles.

When using an ordinal number in similar cases, it is placed before nouns with a definite article: the first chapter the second part - the first chapter, the second part; the third lesson - the third lesson.

Years are indicated by cardinal numbers. When reading the year symbols, the chronological date is divided in half, with each half read as a separate number: 1917 - nineteen seventeen (lit.: nineteen seventeen); 1848 - eighteen forty-eight.

A.S. Pushkin was born in 1799 (seventeen ninety-nine) and died in 1837 (eighteen thirty-seven). - A.S. Pushkin was born in 1799 and died in 1837.

Note. The year designation is also read as follows:

1917 - nineteen hundred and seventeen
1848 - eighteen hundred and forty-eight

Dates are indicated by ordinal numbers:

7th November, 1917 (the seventh of November, nineteen seventeen)
November 7th, 1917 / November 7, 1917 - November the seventh, nineteen seventeen

When denoting arithmetic operations, the verb expressing the result of the action can be either singular or plural;

Five and four is (are) nine.
Nine minus five is (are) four.
Three times four is (are) twelve.

Cardinal numbers over one are used with plural nouns:

There are three classes of reactors: slow, intermediate and fast. - There are three types of reactors: slow, intermediate and fast neutron reactors.

In English, two-digit and multi-digit numbers ending in one are used with plural nouns:

There are thirty-one days in January. - There are thirty-one days in January.

FRACTIONAL AND MIXED QUANTITIES

Simple fractions are expressed using cardinal numbers in the numerator and ordinal numbers in the denominator:

1/3 - a (one) third
1/5 - a (one) fifth
1/6 - a (one) sixth
1/100 - a (one) hundredth

Fractional values ​​1/2 and 1/4 are expressed in special words: a (one) half (1/2); a (one) quarter (1/4).

Note. If a noun is preceded by the word half, then the article is placed immediately before the noun:

Half a kilometer - half a kilometer
half an hour - half an hour
half the distance - half the distance

A kilometer and a half - one and a half kilometers
an hour and a half - an hour and a half

If the numerator contains a number greater than one, then the ending -s is added to the word denoting the denominator:

2/3 - two thirds
4/9 - four ninths
3/5 - three fifths
9/10 - nine tenths

The noun that follows the fractional number is singular:

5/8 inch - 5/8 inches (read: five eighths of an inch)
3/5 foot - 3/5 foot (read: three fifths of a foot)

The noun that follows a mixed number is plural:

2 1/4 meters - 2 1/4 meters (read: two and a quarter meters or two meters and a quarter).

Decimal fractions are separated from the whole number by a dot, not a comma, as in Russian: 1.34; 0.8 (or.8).

Decimal fractions are read as follows:

0.8 or .8 - point eight (point eight) or nought point eight (zero point eight) or o point eight (zero point eight)
0.006 - point nought nought six or nought point two oes six or o point two oes six
1.02 - one point thought two or one point about two
4.25 - four point twenty-five or four point two five

The noun that follows a decimal is singular if there are no whole units in the fraction, and plural if there are whole units in the fraction:

0.5 centimetre - reads: nought point five of a centimetre
5.2 centimeters - read: five point two centimeters

Note. When reading decimals, there is a short pause between the numeral denoting a whole number and the word point.

FUNCTIONS OF NUMERALS IN A SENTENCE

Numerals can perform the following functions in a sentence:

1) Subject:

238 is the total number of protons and neutrons in uranium-238. - 238 - the total number of protons and neutrons in uranium-238.

2) Additions:

Zero in English

Zero in English is called in different words: zero, o (read as a letter), nill, nought. In general, they are equivalent, but there are slight differences.

  • Zero– the most reliable and neutral of these words, zero is a mathematical zero, a temperature zero (zero degrees). To avoid confusion, it is better to say “zero”.
  • O– often used instead of “zero” in colloquial speech when you need to name a number (for example, in a phone number).
  • Nill– literally “nothing”, usually used when talking about the score in a game: Argentina – five, Jamaica – nill.
  • Nought– also “nothing”, practically not used in the USA, in British English it is already considered obsolete.
  • There are also very highly specialized, slang zeros, for example “love”– zero when scoring in tennis. There is an interesting version (this is more of a story than a scientific hypothesis) that the French called a score of zero points “egg” (similar to zero), in French “l’œuf”. The British adopted, somewhat distorting, this term and it turned into “love”.
