We use adjectives all of the time to describe nouns. In Spanish, many times, the adjective follows the noun in grammatical order whereas in English the noun comes after the adjective.
Example: La casa verde = The green house
Here are some adjectives you can use to describe people you know. Be careful though, as the ending (o, os, a, as) determines gender and number. For example, the black dog = el perro negro; the black dogs = los perros negros; the black dog (female) la perra negra; the black dogs (female) = las perras negras. Notice that the article (the) changes with the gender and number of the noun as well as the adjective.
Adjectives:
artístico/artística = artistic
atlético(a) = athletic
bueno(a) = good
cómico(a) = funny
organizado(a) = organized
desorganizado(a) = unorganized
estudioso(a) = studious
inteligente = intelligent (this one ends with e, so it doesn't change gender)
malo(a) = bad
perezoso(a) = lazy
serio(a) = serious
simpático(a) = nice
trabajador(a) = hard-working
alto(a) = tall
bajo(a)= short
bonito(a) = pretty
grande= big
guapo(a) = handsome, good-looking
joven = young (does not change for gender, just number, "jóvenes" is plural)
