What is an ordinal number word

Ordinals. lesson. Russian language Grade 6

Probably, every physical education lesson begins with the command «settle in order». When calling your number in order, you use ordinal numbers. In this lesson, you will learn more about the features of such numbers, about the rules for their declension and use.

As you remember, ordinal numbers include words that answer the questions of what? which the? and denoting the order of the items in the count: first, second, fifth, thirtieth, hundredth.

All ordinal numbers are derived from the corresponding cardinal numbers (except for the first and second).

Table 1. Ordinal numbers

2. About order

Let us explain the word «order». «Order» determines the place of an object or creature in the sequence of similar objects and creatures. This idea of ​​order is most often expressed by ordinal numbers (first, second, third, etc.). Note that in this case the numeral is in front of the noun (fifth house, seventh exercise).

However, cardinal numbers can also express our ideas about the order, the number of the object. In this case, the cardinal number is AFTER the noun and the word number can be inserted between them (house five — house number 5, exercise seven — exercise number 7). Do not confuse them with ordinal numbers (fifth house).

3. Grammatical characteristics

Ordinal numbers change in cases, numbers and in singular. hours by birth.

Ordinal numbers are declined like adjectives.

Table 2. Sample declension of ordinal numbers

The declension of the third number differs from the declension of the rest of the ordinal numbers. This number has the same endings as the adjective fox.

Table 3. Sample declension of the third numeral

When declining compound ordinal numbers (consisting of 2 or more words), only the last part is declined.

Table 4. Sample declension of a compound ordinal number

4. Syntactic features and functions

When combined with a noun, ordinal numbers are used in the form of the same gender, number and case as the noun.

First love (about first love)

Seventh day (until the seventh day)

Sixth sense (sixth sense)

XNUMXth Summer Olympics (at XNUMXth Summer Olympics)

In a sentence, ordinal numbers are either definitions or part of the predicate.

I repeat everything the first verse (M. Tsvetaeva)

I will never be the first one! (E. Evtushenko)

Ordinal numbers in Czech. Čísloa řadová

Ordinal numbers in the Czech language change by gender: second, second, second.

The endings are the same as for Czech adjectives:

the masculine ending will be -y
in female -a
on average -e

Exceptions are the numerals první (first) and třetí (third).

Their endings in any way will be -i.

For everyone else, we add the ending ý, á or é to the number itself.

Sometimes there are changes in the number itself, but it is easy to remember.

Ordinal numbers in French

Ordinal numbers indicate the order of items when counting.

Education

To form an ordinal number, it is necessary to add the suffix to the usual (quantitative) number -ieme:

trois → troisième (three is the third)

Special cases

• «First» = premier; «First» = premiere.
• The «second» has two options: second и second, — e.
• If the cardinal number ends in «e», then this letter disappears when the ordinal number is formed: quatre → quatrième (four is the fourth).
• «Fifth» = fifth.
• «Ninth» = ninth.

Compound Numerals

If a numeral consists of two or more elements, the suffix -ième is used only for the latter:

dix-sept → dix-septieme (seventeen — seventeenth)

Harmonization of ordinal numbers

Ordinal numbers agree in gender and number with the word to which they relate: a letter is added in the feminine gender -e (for two numerals — «first» (première) and «second» (seconde)), in the plural is added -s:

Les premiers froids de la saison. — The first colds of the season.

Abbreviations of ordinal numbers

When reducing ordinal numbers in the text, it is customary to write the numeral with a digit and put a letter on top -e (for those ending in -ième), -R (for premier),  to (for the première). If the number is plural, the final is also added. -s.

examples:

Nombre ordinalAbreviation

premier	1er
first	1ers
premiere	1re

Cardinal and ordinal numbers in English

You might think that it makes no sense to study numerals in English. Indeed, it is easier to write the necessary numbers on a piece of paper and just show them to an English-speaking friend (and to any other friend who passed the numbers at school).

But what to do if a situation arises when there is no piece of paper at hand or there is no way at all to draw something on the sand / napkin / other surfaces. For example, when you speak to a business partner on the phone or call the automated call center at London Airport.

And in general, knowledge of numbers in English will not be superfluous.

You didn’t think, when you learned the English alphabet, about its need, but you took it for granted. Moreover, this process is simple and interesting.

Numbers in English (quantitative numerators)

• What is easiest to memorize? Rhymed poetry. The British seem to have specially invented numbers that are easy to rhyme. Meaning quantitative numerals. That is, those with which you can count objects. We take numbers from 1 to 12 and memorize simple rhymes:

One, two, three, four, five, six, seven,
Eight, nine, ten, eleven, twelve.

We repeat this mantra 10 times and consider that the first stage has been passed.

• The second step is to learn the cardinal numbers from 13 to 19. If we were talking about a person’s age, then many would call people from 13 to 19 years old teenagers. And it is no coincidence. It’s just that at the end of each of these numbers there is the same ending. —teen… And here is the confirmation:

thirteen
fourteen
fifteen
sixteen
seventeen
eighteen
nineteen

• Let’s go further? We take dozens. They are very similar to the numbers 13 through 19, but they have an important difference. Instead of a teenage ending, we add –Ty.

Twenty
thirty
forty
fifty
sixty
seventy
eighty
ninety

• Do you think it will be more difficult further? Don’t even hope. How do we speak Russian 21? The same in English:

twenty one

Fine, fine. Have noticed. Yes, a hyphen is placed between ten and one. But otherwise, everything is the same. Take a look:

Thirty-four, fifty-seven, eighty-two.

• Let’s not waste time on trifles. And let’s move on to more impressive numbers.

Hundred — 100
Thousand — 1000
Million — 1000000

If this is not enough for us, then we can make 200 (two hundred) or 3000 (three thousand), or even immediately 5000000 (five million).

It is surprising that the British did not complicate anything here. Note that a hundred, a thousand, a million are not plural. Everything is in one.

• Still, let’s try something more complicated. Let’s look at composite numbers. For example, 387. We place bets, gentlemen, who will pronounce this number how? And now the correct answer is:

three hundred AND eighty-seven.

The only difference from the Russian is the appearance of the union “and” between hundreds and tens.

What about 5234? We place our bets again. Correct answer:

Five thousand two hundred and thirty-four.

Ordinal numerators

• Cardinal numbers did a good job as a warm-up. It’s time to move on to ordinal in English. That is, to those numerals that denote the order of objects: first, second, third twenty-fourth, the calculation is over!

And here one little surprise awaits us. All ordinal numbers are obtained in the same way: the article is simply added to them the front and —th at the end of a word. And all the cases.

the fourth
the fifth
the sixth
the seventh
the eighth
the ninth
tenth
the forty-seventh

But English wouldn’t be so interesting if it weren’t for the exceptions to the rule. And, of course, these exceptions are the most commonly used numerals.

the first
second
the third

Who has not guessed yet, this is the very first, second and third.

• For dessert. A little more theory for the most curious. This is no longer as necessary as knowledge of cardinal and ordinal numbers, but it will help you show yourself to be very educated in the environment of English-speaking interlocutors.

Phone number. How do you say in Russian 155-28-43? Yeah: one hundred fifty five, twenty eight, forty three. And in English you will call each number in turn. And a little nuance: when there are 2 identical digits in a row, you need to say double and name the number. In this example: one double five two eight four three.

Year. For example, 1843. In Russian: one thousand eight hundred and forty-third. That is, as a number, and even ordinal. And the British are not bastard. Their years are pronounced in dozens at once: eighteen forty-three. That is, also numbers, but quantitative, without any –Th.

All kinds of numbers, numbers, dates, times, as well as words denoting the amount of something are called numerals. English learners need to know as much as possible about these words, as they are almost impossible to do without.

As in Russian, in English, numbers are subdivided into those that indicate the number of objects in the count, and those that indicate their order. You can read about the quantitative numbers of the English language in the corresponding article on our blog. And now we will talk about ordinal numbers.

Formation of ordinal numbers in English

Ordinal numbers in English determine the order of objects when counting and answer the question which? (which, which). They are formed by adding the suffix -th to the cardinal number. We suggest that you learn the first 12 ordinal numbers, since among them you will find exception words, to which the suffix is ​​added according to a different principle.

• 1 — one — first;
• 2 — two — second;
• 3 — three — third (three — third);
• 4 — four — fourth (four — fourth);
• 5 — five — fifth (five — fifth);
• 6 — six — sixth (six — sixth);
• 7 — seven — seventh (seven — seventh);
• 8 — eight — eighth (eight — eighth);
• 9 — nine — ninth (nine — ninth);
• 10 — ten — tenth (ten — tenth);
• 11 — eleven — eleventh (eleven — eleventh);
• 12 — twelve — twelfth (twelve — twelfth).

Well, in such ordinal numbers as the twentieth, thirtieth, fortieth, etc., we change the final -y to -ie:

• 20 — twenty — twentieth;
• 30 — thirty — thirtieth;
• 40 — forty — fortieth.

For compound ordinal numbers of the English language, it is characteristic that only the last word takes the form of an ordinal number, and all the rest remain quantitative:

• 53 — fifty three — fifty-third;
• 307 — three hundred and seven — three hundred and seventh;
• 600 — six hundred — six hundredth;
• 9000 — nine thousand — nine thousandth;
• 1000 — one million — one millionth.

We figured out how ordinal numbers are formed. Now let’s watch a video tutorial on how to pronounce them.

How ordinal numbers are spelled in English

We use ordinal numbers not only in oral speech, but also in writing. Therefore, it is important to know not only how they are pronounced, but also how they are spelled. To do this, you need to remember just a few rules.

1. If we designate an ordinal number with a digit, the corresponding ending is added to it.
   • 1 — first — 1st;
   • 5 — fifth — 5th;
   • 10 — tenth — 10th.

   When writing dates, the article the and the preposition of are often omitted, but are always spoken orally. Read more about writing dates in British and American English in our article.

   We write: The anniversary is on 5th May. — Anniversary of the fifth of May.
   We speak: The anniversary is on the fifth of May. — Anniversary of the fifth of May.

2. All compound ordinal numbers from 21 to 100 in English are hyphenated.
   • 21st — twenty-first;
   • 32nd — thirty-second;
   • 43rd — forty-third;
   • 77th — seventy-seventh;
   • 99th — ninety-ninth.
3. Ordinal numbers with more than two digits are written in separate words. The word and appears between hundreds and tens.
   • 335th — three hundred and thirty-fifth;
   • 421st — four hundred and twenty-first;
   • 5,111th — five thousand, one hundred and eleventh.

It is worth remembering these simple rules, and you will not make mistakes in the spelling of ordinal numbers.

The use of ordinal numbers in English

Despite the fact that numerals in English are an independent part of speech, most often they refer to some kind of noun. Therefore, they are preceded by either the definite article the or the possessive pronoun (my — mine; his — his):

Lesson 25. Ordinal numerals in English. Ordinal numbers in English

Daria SorokinaLinguist-translator, teacher of foreign languages.

In this topic, we will look at how to build an ordinal and give the exact date. There are two types of numerals:

• Quantitative cardinal numerals (denote the number of items), for example, one 1, two 2, three 3 and others;

• Ordinal ordinal numbers (indicate the order of items), for example, first, second, third and others.

Ordinal table (listen)

Examine the suggested table.

We’ve divided all the numbers into four columns.

Features of the formation of ordinal numbers

First of all, we study the numbers from 1 to 12. These numbers are formed using the suffix th. We add this suffix to the cardinal, for example, four — the fourth (fourth).

However, pay attention to the first three numbers, which are exceptions, that is, they do not form an ordinal number according to the rule, for example, one — the first (first), two — the second (second), three — the third (third).

We will also highlight the numerals five — the fifth (fifth), twelve — the twelfth (twelfth) as the final voiced sound [v] stunned when adding a suffix th.

Next, we will consider the numbers from 13 to 19, which are also formed according to the rule by adding the suffix th to the cardinal number.

Numerals denoting tens are formed according to the same rule, only it should be noted that cardinal numbers end with the letter y, which always changes to a letter when adding suffixes or endings i+e+th, for example, twenty — the twentieth (twentieth), thirty — the thirtieth (thirtieth).

The numbers of the fourth group from 100 onwards are formed according to the rule, that is, we add the suffix th to hundreds and thousands, for example, hundred — the hundredth (hundredth), two hundred — the two hundredth (two hundredth), three thousand — the three thousandth (three thousandth).

If we have a composite numeral consisting of tens and ones, then we change the last digit, for example, fifty-three — the fifty-third (fifty fifth), one hundred and eighty-four — the one hundred and eighty-fourth (one hundred eighty fourth).

Once again, we note the important points.

• Numbers first, second, third — exceptions (first, second, third);
• Sound changes [v] on [f] (five — the fifth, twelve — the twelfth)
• Letter changes y on ie + th (forty — the fortieth)

Ordinal in English are always used with the definite article the, accordingly, exact dates are also used with the article, for example, the first of June or June the first (first of June).

Let’s remember, if we want to talk about an event that happened on a certain date, then we need to use the preposition before the phrase one; for example, on the first of June (June XNUMXst).

Numbers in English

It is difficult to meet a person who cannot count to 10 in English, but English numbers greater than ten raise many questions, and many do not fully know how to call them correctly, so they avoid calling large numbers or working with fractions. In this article, I will tell you in great detail (and I will remind someone) what numbers are in English, and how to call numbers in English.

In English, as in Russian, there are two types of numerals: quantitative and ordinal.

Cardinal numbers

Quantitative answers to the question «How much?» and, as their name implies, indicate the quantity:

1	2	3	4	5	6	7	8	9	10
one	Two	three	four	five	six	seven	eight	nine	th

This row is familiar to everyone, but I still ask you to pay attention to the pronunciation of the words: three [θriː], so that you have an English sound [θ], not Russian C, but in the words five and seven, try not to deafen the sound [v ]: [faɪv], [ˈsev.ən].

To form numbers second ten (11-19), the suffix -teen is added to simple numbers, but not to all, as there are exceptions (11,12):

11	12	13	14	15	16	17	18	19
eleven	twelve	thirteen	fourteen	fifteen	sixteen	seventeen	eighteen	nineteen

Please also note that in some numbers, when a suffix is ​​added, the spelling changes (thirteen, fifteen, eighteen).

It is important to remember about stress. At transfer or invoice, the stress falls on the first syllable, because all numbers in a row with the same suffix:

thirteen, fourteen, fifteen, sixteen,

If you use in speech one numeral, not in a number row, but, for example, with a noun, then the stress falls on the second syllable:

She is thirteen years old. — She is 13 years old.
There are fourteen books. — There are 14 books.

For the formation of numerals denoting dozens of, the suffix -ty is used:

20	30	40	50	60	70	80	90
Twenty	thirty	forty	fifty	sixty	seventy	eighty	ninety

Note the changes in the numbers 20, 40, 50.

Since -teen and -ty have similar pronunciations, it is important pronounce the endings clearly numerals to avoid misunderstanding and distortion of information.

Two-digit numbers are usually hyphenated:

22 — twenty-two
48 — forty eight

For naming hundreds we use the word hundred, and thousand — thousand, and these words are in the singularwhen we know exact amount hundreds and thousands:

100 — one hundred 1000 — one thousand 500 — five hundred

5000 — five thousand

Using the words hundreds and thousands is only possible if we do not know the exact quantities:

Hundreds of books — hundreds of books
Thousands of people — thousands of people

A million in English is million, and a billion is billion. These words are also used in singular with exact number… Hundreds, thousands, millions, and billions can separated by commas for a better perception of the whole number:

1,259,126 — one million two hundred and fifty-nine thousand one hundred twenty-six 6,241,491,960 — six billion two hundred and forty one million, four hundred and ninety-one thousand, nine hundred and sixty millions of people — millions of people

billions of dollars — billions of dollars

Ordinals

These numbers answer the questions “Which one? What is the order?«, Indicate the place of a certain subject in the quantitative series. Ordinal numbers are formed using the -th suffix, which is added in most cardinal numbers, with the exception of three:

1 — one	1st — (the) first
2 — two	2nd — (the) second
3 — three	3rd — (the) third

The ordinal number is preceded by the definite article the if there is no other determinant. Adding -th to numbers is usually straightforward, but there are a few «problematic» numbers that have some spelling changes when -th is added:

5 — five	5th — (the) fifth
8 — eight	8th — (the) eighth
9 — nine	9th — (the) ninth
12 — twelve	12th — (the) twelfth

In addition, in the numbers denoting dozens of, final letter y changes to ie before adding -th:

twenty — twentieth fifty — fiftieth

ninety — ninetieth

Ordinal numbers of two-digit, three-digit, etc. numbers are formed by adding -th to the last numeral:

35th — the thirty-fifth 78th — the seventy-eighth

257th — the two hundred and fifty-seventh

Using the AND conjunction in numerals

Should I or should I not say and? We come across different options and so on to the end and cannot understand when we need the union and in numbers. And it turns out that you say and, then you skip. To clear your mind, consider when and is used in numbers.

And is not used in two-digit numbers less than a hundred:

75 — seventy-five 24 — twenty-four

98 — ninety-eight

And is used after the word hundred, if it is followed by dozens of:

132 — one hundred and thirty two 718 — seven hundred and eighteen

304 — three hundred and four

And is used after the word thousand, if it is followed by dozens of, without hundreds:

1086 — One thousand and eighty six 6007 — Six thousand and seven

4020 — four thousand and twenty

If after the word thousand followed by hundreds (a number greater than one hundred or equal to one hundred), then and not used:

2589 — two thousand five hundred eighty nine 5100 — five thousand one hundred

9634 — nine thousand six hundred thirty four

In American English (AmE) and is often overlooked, so you can see numbers with hundred, thousand without and.

The word and in numerals is always unstressed, and its pronunciation is reduced to [ən], [nd], [n].

And is used when reading common fractions (common fractions or simple fractions):

1 1/2 — one and a half
3 2/3 — three and two thirds

You will learn how to correctly name simple and decimal fractions in the next article.

Ordinals

• Formation of ordinal numbers
• Spelling
• Declination

Ordinals Are words that denote the order of items when counting. Ordinal numbers answer the questions: which ?, which ?, which ?, which? or what?, what?, what?, what? (by invoice):

seventh, seventh, seventh, seventh.

Plural ordinal numbers are used with plural or non-singular nouns:

tenth rows, early days;

second scissors, fifth glasses, seventh pants.

If ordinal numbers are used with the names of months, then the name of the month is put in the genitive case:

the first of September, about the first of September, before the first of September.

Ordinal numbers denoting a significant (holiday) date are written with a capital letter:

May XNUMX, March XNUMX.

If a numeral is written in numbers, then the following word is written with a capital letter:

May 9, March 8.

Formation of ordinal numbers

Ordinal numbers are formed from the stem of the corresponding cardinal numbers and adjective endings.

Gender Endings Male Female Intermediate Pl. number

-TH, -II, -OH

-AH, -YA

-OE, -EE

-S, -s

When forming from the base, the soft sign at the end is discarded:

six — sixth, sixth, sixth, sixth;

twenty — twentieth, twentieth, twentieth, twenties.

Complex ordinal numbers from 50 to 80 and from 200 to 900 are formed from the genitive cardinal numbers:

Quantitative Ordinal case case

fifty	fiftyи	fiftyth
sixty	sixtyи	sixtyth
seventy	seventyи	seventyth
eighty	eightyи	eightyth
two hundred	two hundred	two hundredth
three hundred	three hundred	three hundredth
four hundred	four hundred	four hundredth
five hundred	five hundred	five hundredth
six hundred	six hundred	six hundredth
seven hundred	seven hundred	seven hundredth
eight hundred	eight hundred	eight hundredth
nine hundreds	nine hundred	nine hundredth

Ordinals first и second are non-derivatives, that is first и second they are original words, not derived from any other words.

Numerals are specially formed third (from three), fourth (from four), seventh (from seven), fortieth (from forty), hundredth (from one hundred), thousandth (from thousand) and millionth (from million).

Spelling

Ordinal numbers formed from complex cardinal numbers are written in one word:

seventieth, four hundredth.

Ordinal numbers ending in -XNUMXth, -thousandth, -millionth, -billionth, are written in one word:

five hundredth, three thousandth, one hundred millionth, two billionth.

The numeral will be written with a hyphen if before -XNUMXth, -thousandth, -millionth, -billionth the number is written in numbers. In such designations, a hyphen is placed between numbers and -XNUMXth, -thousandth, -millionth, -billionth:

7th, 12th, 100th, 235th.

If an ordinal is used in the name of the holidays after the words holiday, date, day, then it is put in the nominative case and is written with a capital letter:

for the holiday Eighth of March, for the significant date Ninth May, before the holiday First of September.

Declination

Ordinal numbers change by case, number, and in the singular and by gender. They agree with nouns like adjectives and are inflected like adjectives:

Singular number Husband. born genus birth and. R. D. V. T. P.

fifth fight	fifth pit	fifth case	fifth places
fifth fight	fifth pit	fifth case	fifth places
fifth fight	fifth pit	fifth case	fifth places
fifth fight	fifth pit	fifth case	fifth places
the fifth fight	fifth pit	fifth thing	fifth places
about the fifth fight	about the fifth pit	about the fifth case	about fifth places

The accusative case of masculine and plural in numerals consistent with inanimate nouns coincides with the nominative case:

V.P.	I. p.
see	fifth	the battle —	fifth	the battle,

V.P.	I. p.
see	fifth	places —	fifth	place.

The accusative case for numerals consistent with animate nouns coincides with the genitive case:

V.P.	R.P.
see	fifth	there is no fighter	fifth	fighter,

Numeral third declines like possessive adjectives in -I:

I.R.D.V. T.P.

the third	third	the third	third
the third	third	the third	the third
third third	third	third	third third
the third	third	the third	third
about the third	about the third	about the third	about the third

In compound ordinal numbers, the ordinal form has only the last word. When declining such numerals, only the last word changes:

I.R.D.V. T.P.

one hundred twenty-eighth

one hundred twenty-eighth

one hundred twenty-eighth

one hundred twenty-eighth one hundred twenty-eighth

one hundred twenty-eighth

Morphological signs

Ordinal numbers, like adjectives, change by gender, number and case: the seventh car (singular) — seventh cars (plural), tenth part (singular) — tenths (plural) …

m. r.	second section	fourth goal
g. R.	second half	fourth quarter
Wed R.	second trip	fourth place

I. p.	first entrance	eighth minute
R.P.	first entrance	eighth minute
D.P.	first entrance	eighth minute
V.P.	first entrance	eighth minute
T.p.	first entrance	eighth minute
Par.	(about) the first entrance	(about) the eighth minute

1. The endings of ordinal numbers are written in the same way as the endings of adjectives.
2. When specifying the date after the ordinal number, the name of the month is put in the genitive case: by the first of May, before the thirty-first of December, until the eighth of March.
3. Ordinal numbers in the names of events and holidays of the Russian Federation after the words holiday, date and day are put in the nominative case. For example: Students released a newspaper for the landmark date May XNUMXth.

Syntactic signs

Ordinal numbers can be any member of a sentence. Most often, in agreement with nouns in gender, number and case, they act as a definition.

• Substitutefifthmagazine number.
• Firstday in the camp was rainy.
• One hundred forty seventh to Adler did not come.
• Our athlete — first.
• Stop byfirst number.

* Note:

The inclusion of these words in the category of numerals is traditional and relies exclusively on the close derivational and semantic connection of ordinal numbers with quantitative ones (cf. nine — ninth, ten — tenth, thirty — thirtieth).

The proximity of ordinal numbers to cardinal numbers also affects the use of cardinal numbers in the meaning of ordinal numbers, for example, when designating an address: house forty-seven, apartment eighteen instead of house forty-seventh, apartment eighteenth.

There is another approach in linguistics. So, Vinogradov V.V. and the authors of textbooks for universities refer words with ordinal meaning to the category of relative adjectives, since 1). the declension system of ordinal words and adjectives is the same: the second, the second — bold, bold; 2).

the formation and morphological structure of ordinal words and adjectives do not differ: thousandth and iron, fortieth and secular, third and fox, five-tenth and pentagonal; 3).

some ordinal numbers can acquire a qualitative meaning, usually conditioned by phraseological terms: the first violin, in the background, in the third hands.

Rules for the use of ordinal numbers

Ordinal numbers in English must be preceded by the definite article the, regardless of whether they are followed by nouns or not.

This vase is the twentieth in my collection. “This vase is the twentieth in my collection. 

The article is placed only before the first word in a compound numeral, and the ending -th is added only to the last word, while the rest of the spelling is preserved — after hundreds, the union and is put, and between tens and ones — a hyphen.
