Adjective agreement (-o, -a, -os, -as)

Gender Agreement (-o and -a)

In Spanish, adjectives must match the noun they describe in both gender (masculine or feminine) and number (singular or plural).

For most adjectives, the masculine form ends in -o and the feminine form ends in -a.

Number Agreement (-os and -as)

To make these adjectives plural, simply add -s. A masculine or mixed plural group uses -os, while a strictly feminine group uses -as.

Adjective Placement

In English, we usually put the adjective before the noun (for example, "the red car"). In Spanish, descriptive adjectives typically come after the noun they describe. They still must agree in gender and number with that noun.

Adjectives Ending in -e

Not all adjectives end in -o or -a. Some adjectives end in -e, like grande (big), verde (green), or inteligente (smart). These adjectives are gender-neutral, meaning you use the exact same form for both masculine and feminine nouns.

To make them plural, you still need to match the number of the noun. Just add -s, regardless of the noun's gender.
