Plural Forms

To make a Spanish noun plural, look at how it ends:

• Ends in a vowel: add -s. casa → casas, café → cafés
• Ends in a consonant: add -es. flor → flores, ciudad → ciudades, mujer → mujeres
• Ends in -z: change z to c and add -es. lápiz → lápices, vez → veces, luz → luces, pez → peces
• Ends in -ión: add -es and drop the accent. canción → canciones, habitación → habitaciones
• Watch the written accent: joven → jóvenes and examen → exámenes gain one, autobús → autobuses loses it, país → países keeps it
• Nouns ending in an unstressed -s do not change: el lunes → los lunes, la crisis → las crisis

The articles, numbers and adjectives around the noun tell you whether you need the singular or the plural.
