How to make adjectives agree with the noun

How to make adjectives agree with the noun they modify (Click anywhere to progress through the slideshow. )

In order to make an adjective agree with the noun it modifies, you must know whether the noun is masculine or feminine. Let’s look at some words and identify whether they are masculine or feminine…

What about the word “puerta”? Is it masculine or feminine? That’s right… it’s feminine! What about the word “libro”? Is it masculine or feminine? That’s right… it’s masculine!

What about the word “silla”? Is it masculine or feminine? That’s right… it’s feminine! What about the word “ventana”? Is it masculine or feminine? That’s right… it’s feminine!

What about the word “bolígrafo”? Is it masculine or feminine? That’s right… it’s masculine! What about the word “carro”? Is it masculine or feminine? That’s right… it’s masculine!

OK – we’ve practiced identifying masculine and feminine nouns. But we also need to know whether the noun is singular or plural. Let’s do some practice…

What about the word “puerta”? Is it singular or plural? That’s right… it’s singular! What about the word “libros”? Is it singular or plural? That’s right… it’s plural!

What about the word “sillas”? Is it singular or plural? That’s right… it’s plural! What about the word “ventana”? Is it singular or plural? That’s right… it’s singular!

What about the word “bolígrafo”? Is it singular or plural? That’s right… it’s singular! What about the word “carros”? Is it singular or plural? That’s right… it’s plural!

Now – here’s how to make the adjective agree with the noun: if you have a masculine noun like “libro” and your adjective ends in “-o”, then the adjective stays the same. For example, we’ll use the adjective “rojo” (red). un libro rojo Notice that the adjective comes AFTER the noun – in most cases adjectives will come after the noun in Spanish.

But if the noun is feminine and the adjective ends in “-o”, you must change the “-o” to an -a”. See how the adjective “rojo” changes to “roja” here: una puerta roja

Let’s compare the previous two slides. Note how the adjective that ends in “-o” stays the same with a masculine noun, but changes to “-a” with a feminine noun: un libro rojo una puerta roja

Now, some adjectives, like “verde” (green), end in “-e”. These are easy to deal with because they will stay the same whether the noun is masculine or feminine. Observe: un libro verde una puerta verde Note that the adjective “verde” stays the same regardless of whether the noun is masculine or feminine.

Let’s observe these examples using another adjective ending in “-e”: un alumno inteligente una alumna inteligente Note that the adjective “inteligente” stays the same regardless of whether the noun is masculine or feminine.

Let’s do some practice with masculine and feminine adjectives…

How would you change the adjective “anaranjado” to go with the noun “silla”? That’s right… it’s anaranjada! How would you change the adjective “interesante” to go with the noun “ventana”? That’s right… it stays the same!

How would you change the adjective “importante” to go with the noun “perro”? That’s right… it stays the same! How would you change the adjective “grande” to go with the noun “ventana”? That’s right… it stays the same!

How would you change the adjective “mojado” to go with the noun “silla”? That’s right… it’s mojada! How would you change the adjective “alto” to go with the noun “alumna”? That’s right… it’s alta!

Now we also need to look at whether the noun is singular or plural. If the noun is singular, the adjective must be singular also. If the noun is plural, the adjective must also be plural. Observe and compare the following: SINGULAR: PLURAL: un libro rojo unos libros rojos Notice in the plural example how the adjective has also been made plural.

Making adjectives plural is easy – just remember this simple rule: If the adjective ends in a vowel, you add an “-s” to make it plural. If the adjective ends in a consonant, you add an “es” to make it plural. Observe and compare the following: Adjective ending in vowel: Adjective ending in consonant: unos libros rojos unos libros azules Notice how “rojo” was changed to “rojos”, but “azul” was changed to “azules”.

Let’s do some practice with making adjectives plural…

How would you make the adjective “amarillo” (yellow) plural? That’s right… it’s amarillos! How would you make the adjective “gris” (grey) plural? That’s right… it’s grises!

How would you make the adjective “interesante” (interesting) plural? That’s right… it’s interesantes! How would you make the adjective “militar” (military) plural? That’s right… it’s militares!
