1. Los Adjetivos

2. Los adjetivos: Adjectives: Words that modify nouns
En español, most adjectives have either two or four forms
When using adjectives in Spanish, one must always consider PLACEMENT and AGREEMENT.

3. ADJECTIVE AGREEMENT:
If an adjective ends in O, A, OS, AS or dor, dora, dores, doras then it will have four forms and the form that you use in any given sentence must agree with the noun that it modifies.
alto (m/s) alta (f/s)
altos (m/p) altas (f/p)

4. ADJECTIVE AGREEMENT:
If an adjective ends in something other than O, A, OS, AS, or dor, dora, dores, doras then it will have only two forms – singular and plural.
grande (s) grandes (p)

5. Exceptions to the rule…:
The adjectives good (bueno) and bad (malo) are descriptive adjectives but are generally placed in front of the nouns they modify.
Also adjectives that reflect an inherent quality of the noun
(cold ice) are also placed in front of the noun.
