Building complete plurals
Carry singular-to-plural changes across the entire noun phrase.
Understand the choice
Plural is a sentence-wide agreement pattern. Once a noun becomes plural, its article, adjective, demonstrative, and verb may all need to change, so scan the complete noun phrase rather than one ending.
Core rule: Make most Spanish nouns plural with -s after a vowel and -es after a consonant; articles and adjectives must become plural too.
Notice it in context
Los trenes son rápidos y las estaciones son grandes.
The trains are fast and the stations are large.
Tren adds -es, estación loses its written accent before -es, and both adjectives agree in number.
Tengo dos clases difíciles.
I have two difficult classes.
Clase adds -s; difícil adds -es and becomes difíciles.
Esos jóvenes viven aquí.
Those young people live here.
Joven becomes jóvenes and gains an accent to preserve stress.
What to remember
- Words ending in -z change z to c before -es: luz becomes luces.
- A mixed-gender group normally takes the masculine plural form.
Common trap: Do not pluralize only the noun: las estación grande is incomplete; say las estaciones grandes.
