Spanish Adjectives have the same function as those in English: they describe the noun. However, the main difference between the two is that the adjectives in Spanish have to agree to the corresponding noun in number or gender, that is to say, the adjective will change if the noun is masculine or feminine or even if it is singular or plural.
CHANGING ADJECTIVES ACCORDING TO GENDER
Changing an adjective from masculine to feminine is rather simple. When masculine adjectives end in “O”, the movement to feminine simply requires changing the last “O” to “A”.
caro / cara
contento / contenta
alto / alta
If a masculine adjective ends in any other letter, there is NO change when the noun is feminine.
CHANGING ADJECTIVES ACCORDING TO NUMBER
Changing adjectives to the plural form usually requires only the addition of one “S” to the end because most adjectives end in vowels.
amable / amables
loco / locos
The movement from singular to plural does not change the definition of any adjective.
Some adjectives, however, end in different consonants. Generally these simple require the addition of “-ES” to the end of the adjective.
fatal / fatales
When adjectives end in “Z”, the “Z” is changed to “C” and then the “ES” is added to the end.
feliz / felices
feroz / feroces
Always keep in mind that Adjectives are usually placed AFTER the noun, unlike English.
Adjust the adjective in the bracket to agree with the noun which precedes it.
