Russian cardinal numbers: How to form them and use them in a sentence?

Numbers

In Russian, as in English, cardinal numbers are the forms of numbers that we use to count and do math. Some examples in Russian are:

  • один[adeen](one)

  • три[tree](three)

  • триста шестьдесят пять[trEEsta sheesdeesYAt pyat](three hundred sixty five)

To use cardinal numbers in Russian, you’ll need to know the basic number words and how to combine them into multi-word “compound” numbers (e.g. 736). But nouns in Russian are especially tricky because, like adjectives, numbers will often need to agree with the noun you quantify! For example, notice the two different the forms of the number один(one) in the phrases below:

  • Masculine noun:

    один день

    adEEN den

    one day

  • Feminine noun:

    одна девушка

    adNA dyeVUSHka

    one girl

  • Neuter noun

    одно дерево

    adNO

    one tree

But one of the more surprising aspects of using numbers in Russian, is that, though the case of a number always reflects the grammatical role the noun plays in the sentence, the noun itself will often appear in a different case entirely: one determined by the number and not by the sentence context. Want to learn more? Read on!

In this post, we’ll first go through how to form Russian numbers, focusing first on the numbers 1-4, which are especially tricky. Then, we’ll briefly talk about the rules for assembling larger numbers. Finally, we’ll talk about how and when nouns or adjectives might take on special forms when they follow Russian numbers.

    What is a “cardinal” number?

    When people hear the word cardinal, many things come to mind. If you are from Arizona or lived there for a while, your first association might be with the football team or a red bird with a prominent crest. If you are Roman Catholic, you might be associating the word with the Pope. But if you have ever studied a foreign language, or are a fellow linguist, then you most certainly think that cardinals, first and foremost, relate to numerals. We call these cardinal numbers.

    A cardinal number is a counting number, a number that is used to indicate quantity (e.g., one or two of something). Cardinal numbers (e.g. “four”) get their name from the fact that they are the principal numbers, and all the other types of numbers, like ordinal numerals (e.g. “fourth”) or collective numerals (e.g “all four”), are derived from these.

    How to use cardinal numbers in Russian?

    All Russian cardinal numbers have several different forms. The form you use will depend on the number’s case, which is determined by the context in which the number is used in a sentence. The numbers 1-3 will also agree with the noun in some other features, which will be discussed below.

    Important

    If you are using a multi-word number in Russian, like 365, all parts of that number will reflect the same case. For example:

    genitive casenominative case

    В России из трехсот шестидесяти пяти дней в году, в среднем сто восемнадцать нерабочие.

    v rasEEee eez tryokhsOt pyatEE dnyey v gadOO f srYEdnyem sto vaseemnAtsat neerabOcheeye

    In Russia, out of the 365 days of the year, on average, 118 are days off.

    In Russian, you’ll need to look at the final digit of the number you are using to determine which set of grammar rules you should follow. There are three main patterns:

    • numbers that end in 1

    • numbers that end in 2, 3, or 4

    • numbers that end in 5, 6, 7, 8, 9, or 0

    In this section, we’ll go through each group of numbers and discuss the patterns you will need to follow. Let’s have a look!

    How to use Russian numbers that end in 1?

    When a Russian number ends in 1, it will always be followed by a singular noun. This applies even when you are using large numbers that end in 1 like 21, 51, or 231.

    singular

    Я прочитал одну интересную книгу.

    ya pracheetAL adnOO eenteerYEsnooyu knEEgoo

    I read one interesting book.

    У нашего канала двадцать один постоянный подписчик.

    oo nAsheeva kanAla dvAtsat adEEN pastaYAnyi padpEEshcheek

    Our channel has twenty one regular subscribers.

    lit. In our channel (are) twenty one regular subscriber.

    Other than that, though, the pattern is very simple. The case of the noun, adjective, and number are all identical and they match the case you would expect, based on the context in which the noun is used.

    Exception!

    The number один can be used before a plural noun, but in this case, it is generally translated instead as “only” or “some,” rather than as a cardinal number.

    • У них в семье одни девочки.

      oo nEEkh f seemYE adnEE dYEvachkee

      They have only girls in the family.

    • По одним сведениям он уехал в Москву, а по другим, в Израиль.

      pa adnEEM svYEdeenyam on ooYEkhal v mAskvoo a pa droogEEM v eezrAeel

      According to some sources, he left for Moscow, and according to others, for Israel.

    In this use it also has special plural forms, which you can read about in the next section!

    Let’s look now at all the agreement forms of the word один[adEEN](one).

    How to decline один (one) in Russian?

    Один[adEEN](one) is declined like an adjective and so it agrees with the noun it quantifies in case, number, animacy, and gender. All the forms of один are illustrated in the chart below.

    How to use Russian numbers that end in 2, 3, or 4?

    When a Russian number that ends in 2, 3, or 4 is used before a noun, the case and number of the noun and of any adjectives that describe it, will be determined by the set of rules listed below.

    • If the context leads us to expect that the noun will be in the genitive, dative, prepositional, or instrumental case, then the number, noun, and adjective(s) all show the same case and number (plural):

      Cardinal Number
      Adjective(s)
      Noun

      genitive

      genitive

      genitive

      dative

      dative

      dative

      prepositional

      prepositional

      prepositional

      instrumental

      instrumental

      instrumental

      We see the same thing in the accusative case, if the noun is animate (living).

    • If the context of a sentence means that the noun should be nominative, follow the rules below instead:

      Gender of Noun
      Cardinal Number
      Adjective(s)
      Noun

      masculine / neuter

      nominative

      genitive plural

      genitive singular

      feminine

      nominative plural

      For example:

      • number (nominative)adjective (genitive plural)noun (genitive singular)

        В комнате живут два хороших студента.

        f kOmnatye zheevOOt dva kharOsheekh stoodYEnta

        Two good students live in the room.

        студе́нт(student) is masculine
      • number (nominative)adjective (nominative plural)noun (genitive singular)

        В комнате живут две хорошие студентки.

        f kOmnatye zheevOOt dvye khorOsheeye stoodYEntkee

        Two good (female) students live in the room.

        студе́нтка(student) is feminine
    • If the context of a sentence means that the noun should be accusative and the noun is inanimate (not living), we follow a similar pattern to the one above, except that the number is in its inanimate accusative form.

      Gender of Noun
      Cardinal Number
      Adjective(s)
      Noun

      masculine / neuter

      accusative (inanimate)

      genitive plural

      genitive singular

      feminine

      nominative plural

      Remember that for animate nouns, all three are accusative plural.

    Tip

    The number will always be in the case that you would “expect” based on the context.

    Let’s look very quickly at the forms of the numbers два[dva](two), три[tree](three), and четыре[cheetYrye](four). As you’ll see, they’re simpler than один[adEEN](one)!

    How to decline два (two), три (three), and четыре (four) in Russian?

    The forms of два[dva](two), три[tree](three), and четыре[cheetYrye](four) are illustrated in the table below. Notice that though they are all marked for case, only два[dva](two) must agree with the gender of the noun.

    How to use Russian cardinal numbers that end in 5, 6, 7, 8, 9, or 0?

    When using other cardinal numbers in Russian, those that do not end in 1, 2, 3, or 4, the pattern is a little simpler than the patterns we discussed for 2, 3, 4, but there the nouns and adjectives do still take some unexpected forms. Check out the chart below:

    Expected Case
    (based on context)
    Number
    Adjectives
    Nouns
    Nominative

    nominative

    Genitive plural

    Genitive plural

    Accusative
    (inanimate)

    accusative
    (inanimate)

    Other cases

    The numbers, nouns, and adjectives are used in the same cases as the numerals.

    Notice that though the “expected cases” that are affected by the exception here are the same ones that we saw for numbers ending in 2, 3, 4, the exceptional pattern itself is quite a bit simpler.

    For example:

    number (nominative)adjective (genitive plural)noun (genitive plural)

    На встрече было пять лучших студентов.

    na fstrYEchye bYla pyat lOOcheekh stoodYEntaf

    In the meeting, there were five best students.

    How to count in Russian?

    When counting in Russian, you will use cardinal numbers most of the time, except that instead of один[adEEN](one), Russians will generally use the word раз[ras](time).

    Russians, like many other people, use their fingers to count. Though in America, most people start counting “one” by putting up their pointer finger, most Russians count a little differently. Here are a couple of the most common ways to count on your fingers in Russia:

    • Start with an open palm, then, one-by-one bend the fingers inward. Most Russians start with the pinkie first and end with the thumb.

    • Start with a closed palm, then, one-by-one, bend the fingers outward. Most Russians start with the thumb and work towards the pinkie.

    What are some common Russian expressions with numbers?

    Here are five common phrases in Russian that use the cardinal numerals 1-5:

    • в один голос

      v adEEN gOlas

      unanimously

      lit. in one voice

      Олимпийские чемпионки заявили в один голос, что не могут поверить в свой успех.

      aleempEEyskeeye cheempeeOnkee zaeevEElee v adEEn gOlas shto nee mOgoot pavYEreet f svOy oospYEkh

    What are some common “mistakes” Russians make cardinal numerals?

    Here are three common “mistakes” Russian native speakers make when using numbers. See if you can hear these “in the wild!”

    • Incorrect declension of hundreds:

      Correct:

      около пятисот человек

      Okala pyateesOt cheelavYEk

      around 500 people

      You may hear:

      около пятиста человек

      Okala pyateestA cheelavYEk

    • Incorrect declension of years:

      Correct:

      в две тысячи двенадцатом году

      v dvye tYseechee dveenAtsatam gadOO

      in twenty twelve (2012)

      lit. in the two thousand and twelfth year

      You may hear:

      в двухтысячном двенадцатом году

      v dvookhtYseechnam dveenAtsatam gadOO

    • Incorrect declension of полтора[paltarA](one and a half):

      Correct:

      в полутора километрах

      f palOOtara keelamYEtrakh

      1.5 km away

      You may hear:

      В полуторах километрах

      f palOOtarakh keelamYEtrakh

    To sum up

    Here is what we discussed in this post:

    • Russian cardinal numbers change their forms depending on the case, number, and gender of the noun they quantify.

    • There are three major grammar patterns:

      • Numbers ending in 1:

        The case of the noun, adjective, and number are all “as expected” except that all nouns are singular.

      • Numbers ending in 2, 3, 4:

        If you expect the noun to be nominative or accusative (inanimate):

        • the noun will be genitive singular

        • if the noun is masculine or neuter, the adjective(s) will be genitive plural

        • if the noun is feminine, the adjective(s) will be nominative plural

        In all other cases, the case and number of the noun/adjective(s) matches the case of the numeral.

      • Numbers ending in 5, 6, 7, 8, 9, 0:

        If you expect the noun to be nominative or accusative (inanimate), the noun and adjective(s) will be genitive plural.

        In all other cases, the case of the noun/adjective(s) matches the case of the numeral.
