Russian Language/Objects in Russian
What changes do the nouns go when they are employed as objects?
Many thanks for your guidance,
Depending on the gender of the noun, a particular ending is applied or changed in different cases. Referring to nouns as objects, you are probably referring to the accusative case where masculine and neutral nouns are identical to nominative case, i.e. unchanged. Feminine nouns change endings in singular to -у or -ю while plurals remain unchanged like in the nominative case.
This works with most nouns but there are more rules. Check http://www.russianlessons.net/grammar/nouns_accusative.php
Let me know know if you feel more curious.
