Adjectives
Adjectives are words that describe nouns. For example, in "cute dog", "cute" is the adjective and it describes the noun "dog". In English, adjectives usually come BEFORE the noun they describe. But in Spanish, they usually come AFTER the noun they describe. "lindo" means "cute", and "perro" means "dog". But Spanish speakers don't say "lindo perro". They say "perro lindo".
Here are examples of adjectives being used:
lindo (cute): el perro lindo (the cute dog)
grande (big): la casa grande (the big house)
azul (blue): la flor azul (the blue flower)
suave (soft): el almohada suave (the soft pillow)
If an adjective ends with the letter "o", the "o" needs to be changed to an "a" when the noun is feminine
lindo (cute): el perro lindo (the cute dog)
lindo (cute): la tortuga linda (the cute turtle)
rico (rich): el hombre rico (the rich man)
rico (rich): la mujer rica (the rich woman)
blanco (white): el piso blanco (the white floor)
blanco (white): la mesa blanca (the white table)
Posessive Adjectives
Possesive adjectives, like "my", "your", or "our" show ownership. In Spanish, posessive adjectives are used before the noun they describe.
mi: used when the owner is "yo"
tu: used when the owner is "tú"
nuestro: used when the owner is "nosotros"
Su: used when the owner is "El", "Ella", "Ellos", "Ellas", "Usted", or "Ustedes"
Vuestro: used when the owner is "Vosotros"
Examples of posessive adjectives being used:
Mi amigo (My friend)
Tu casa (Your house)
Nuestro perro (Our dog)
Nuestra familia (Our family)
Su coche (His/Her/Their/Your car)
Since "su" can mean many things, it's important to know the context of a sentence in order to know what "su" means.
El hombre esta lavando su coche. (The man is washing his car.)
La mujer esta lavando su coche. (The woman is washing her car.)
Usted esta lavando su coche. (You are washing your car.)
Ellos estan lavando su coche. (They are washing their car.)
