GENITIVE CASE AFTER NUMERALS

To indicate a precise quantity, we use the construction "a numeral plus a noun".

When there is one object, a noun is always in the Nominative case and a numeral agrees with the noun's gender:

If there are more objects than one, the construction "a numeral + a noun in Genitive singular or plural" is used. Please, study the tables.

числительное +существительные мужского рода:

числительное + существительные женского рода:

Please, note! The noun agrees with the last numeral!

Please, note the word forms: два / две ("two")

два студента, два доллара (2 + существительные мужского рода)
две студентки, две книги (2 + существительные женского рода)

The invariant (never changing) nouns (see the section "Plural Nouns (continued)") do not change their form even when counted.

Complex sentence with the word «который» (which, that)

To describe a person or inanimate object (i.e. to answer the question: какой? = what is it like?), we can use a complex sentence with the word "который".

The word "который" behaves as an adjective: it is inflected for gender and number to agree with the word it serves as a substitute for.

The same happens when the word "который" serves as a substitute for the inanimate noun:

The form of the word "который" is determined by its function in a subordinate clause, not in the principal one! Please, consult the tables: the clause that starts with the word "который" doesn't change, and it can be added to any principal clause from the left column.
