Nouns — Forming of the Regular Plural

Nouns — Forming of the Regular Plural

Nouns are called singular if they refer to one person or object, plural if they refer to or represent more than one. In English, to indicate the plural form of most nouns, an s is added to the singular form: book, books; rule, rules; ware, wares; American, Americans.

In Spanish, nouns which end in a vowel regularly add -s to the singular to form the plural. The definite article must have the same gender (masculine or feminine) and the same number (singular or plural) as the noun.

el gato	cat	los gatos	cats
la casa	house	las casas	houses
el libro	book	los libros	books
la silla	chair	las sillas	chairs

Nouns ending in a consonant (including y) add -es to the singular to form the plural.

el rey	king	los reyes	kings, monarchs
la pared	wall	las paredes	walls
la estación	station, season	las estaciones	stations, seasons
la lección	lesson	las lecciones	lessons
