An adjective matches its noun in gender, number and case. In the basic form that is -ый or -ой for masculine, -ая for feminine, -ое for neuter and -ые in the plural: хороший кофе, хорошая книга, хорошее вино.
Examples
- Это хороший кофе.
- This is a good coffee.
- Хлеб свежий.
- The bread is fresh.
- Холодное пиво, пожалуйста.
- A cold beer, please.
The mistake to avoid
The adjective moves whenever the noun's case moves, not only when its gender does.
