An adjective changes its form to agree with the noun it describes. Look at the red book and the red houses.
The idea
Many adjectives ending in -o have four forms: rojo, roja, rojos and rojas. Match masculine or feminine and singular or plural to the noun. Adjectives in -e, such as grande, usually keep the same gender form but still have a plural: grandes.
Examples
- El libro es rojo.The book is red.
- La casa es roja.The house is red.
- Los libros son rojos.The books are red.
- Las casas son rojas.The houses are red.
- La ventana está abierta.The window is open.
- Los estudiantes están cansados.The students are tired.

Watch out
A noun’s grammatical gender need not match the gender of its translation in your language. Not all adjectives follow the -o/-a pattern.
