Russian language
In Russian, an adjective must agree with the word that it describes in gender, case and number. In the nominative case, adjectives that describe feminine words usually end in -ая or -яя. Those that describe masculine words usually end in -ый, -ий or -ой. Those that describe neuter words usually end in -ое or -ее. Those that describe plural words usually end in -ые or -ие. The endings change depending on case.
