15. Let’s check out how to talk
about a boy, then a girl.
• el muchacho alto
• la muchacha alta
16. What about more than
one boy and more than
one girl?
• los muchachos altos
• las muchachas altas
17. Many common adjectives end in -o.
These adjectives have four forms. The
following words all mean “red:”
• rojo
• roja
• rojos
• rojas
18. The correct form of the adjective depends
upon the noun it modifies. Is the noun
masculine or feminine? Singular or plural?
• el teléfono rojo
• la casa roja
• los teléfonos rojos
• las casas rojas
19. Notice how the endings
are the same:
el teléfono rojo
la casa roja
los teléfonos rojos
las casas rojas
21. Easy. Adjectives that
end in -e also change
form for singular or
plural. To form the
plural, simply add -s
la muchacha inteligente
las muchachas inteligentes
22. Easier yet...adjectives that end in
-e do not change form for
masculine or feminine.
el muchacho inteligente
la muchacha inteligente
los muchachos inteligentes
las muchachas inteligentes
23. In much the same way, most
adjectives that end in a consonant
do change form for singular or
plural, but do not change for
masculine or feminine. To form the
plural, add
-es.
el muchacho popular
la muchacha popular
los muchachos populares
las muchachas populares
25. Here it is...
• Adjectives ending in -o have four forms: alto,
alta, altos, altas
• Adjectives ending in -e have two forms:
inteligente, inteligentes
(form plural by adding –s)
• Most adjectives ending in a consonant have two
forms: popular, populares
(form plural by adding -es)
