Plural means noun plus article
In Spanish, plural usually changes two things: the noun ending and the article before the noun. El libro becomes los libros; la mesa becomes las mesas.
el libro -> los librosla mesa -> las mesas

Formación del plural
First change the article. Then change the noun.
Spanish plural is a small system. Learn the noun ending, then always check that the article agrees with the plural noun.
Singular
Plural
Examples
Note
Ends in vowel
+ s
casa -> casas, libro -> libros, café -> cafés
The article changes too: la casa -> las casas.
Ends in consonant
+ es
mujer -> mujeres, papel -> papeles, mes -> meses
This is the main pattern for consonant endings.
Ends in z
z -> c + es
lápiz -> lápices, pez -> peces, luz -> luces
The spelling changes before -es.
Ends in stressed -s
+ es
autobús -> autobuses, país -> países
Spoken stress matters; learn common words as complete phrases.
Ends in unstressed -s
noun stays the same
lunes -> lunes, crisis -> crisis
The article shows plural: los lunes, las crisis.
Articles
el -> los, la -> las
un -> unos, una -> unas
Do not leave the article singular when the noun is plural.
Detailed grammar
Singular to plural is pattern recognition.
Lesson 1 gave you el and la for people. Lesson 2 gave you object gender. Lesson 3 connects both: noun ending, article, number, and mixed groups.
Vowel ending: add -s
If the singular noun ends in a vowel, add -s. This is the easiest and most common pattern.
casa -> casaslibro -> libroscafé -> cafés
Consonant ending: add -es
If the noun ends in a consonant, add -es. This includes many useful A1 words for people, places, and objects.
mujer -> mujerespapel -> papelesmes -> meses
Z changes to c before -es
A word ending in z changes z to c before adding -es. This keeps the spelling and sound natural.
lápiz -> lápicespez -> pecesluz -> luces
Mixed groups use los
When a group has masculine and feminine people together, Spanish normally uses the masculine plural.
el abuelo + la abuela -> los abuelosel hermano + la hermana -> los hermanos
Some plurals do not look new
Words ending in unstressed -s often keep the same noun form. The article still changes, so the phrase becomes plural.
el lunes -> los lunesla crisis -> las crisis
La mujer lee un libro.
The woman reads a book.
Singular: la mujer, un libro.
Las mujeres leen dos libros.
The women read two books.
Plural: las mujeres, dos libros.
Hay un bolígrafo y dos lápices en la mesa.
There is one pen and two pencils on the table.
Count objects with the number plus the noun phrase.
El abuelo y la abuela de María son los abuelos de María.
Maria's grandfather and grandmother are Maria's grandparents.
A mixed family pair becomes masculine plural: los abuelos.
El pez está en el vaso; los peces están en los vasos.
The fish is in the glass; the fish are in the glasses.
Z changes to c: pez -> peces.
El lunes estudio; los lunes estudio también.
On Monday I study; on Mondays I study too.
Lunes does not change, but el becomes los.
