Spanish builds adjectives from nouns and verbs through a small set of highly productive suffixes. Once you recognize them, you can often guess the meaning of a new adjective without a dictionary, and you can even coin your own adjectives the way native speakers do.
Full of Something: -oso / -osa
The suffix -oso (feminine -osa) attaches to nouns and means full of or characterized by. It corresponds roughly to English -ous or -y: peligro becomes peligroso (dangerous), fama becomes famoso (famous), misterio becomes misterioso (mysterious).
Escalar esa montaña es bastante peligroso en invierno.
Climbing that mountain is quite dangerous in winter.
La cantante se volvió famosa después de su primer disco.
The singer became famous after her first album.
Ability and Possibility: -able, -ible
The suffixes -able and -ible correspond directly to English -able and -ible. They usually attach to verbs and describe something that can be done. Use -able with -ar verbs and -ible with -er and -ir verbs as a general guideline.
Tu abuela siempre fue una persona muy amable con todos.
Your grandmother was always a very kind person to everyone.
Las estrellas son visibles solo cuando el cielo está despejado.
The stars are visible only when the sky is clear.
Relation and Activity: -ivo, -al
The suffix -ivo/-iva describes something that performs an action or has a tendency: activo (active), creativo (creative), expresivo (expressive). The suffix -al makes an adjective meaning related to a noun: nación gives nacional (national), cultura gives cultural, persona gives personal.
El himno nacional se canta al comienzo del partido.
The national anthem is sung at the start of the game.
Origin and Nationality: -ano, -ense, -eño
Spanish has several suffixes that describe where someone or something is from. -ano/-ana is very common and attaches to country or city names: mexicano (Mexican), cubano (Cuban), italiano (Italian), colombiano (Colombian).
Mi vecino mexicano nos invitó a una comida tradicional.
Our Mexican neighbor invited us to a traditional meal.
The suffix -ense is also common for nationalities and city adjectives: nicaragüense (Nicaraguan), costarricense (Costa Rican), estadounidense (from the United States). It doesn't change for gender.
La escritora nicaragüense ganó un premio internacional.
The Nicaraguan writer won an international award.
The suffix -eño/-eña is especially common for cities and regions: madrileño (from Madrid), limeño (from Lima), panameño (Panamanian), hondureño (Honduran), caribeño (Caribbean).
El ritmo caribeño te hace bailar sin darte cuenta.
The Caribbean rhythm makes you dance without realizing it.
