How to Make Adjectives Agree with Nouns in Spanish - Spanish Learning Lab (2024)

In the previous lesson, we explained the rules foradjective placementand talked about the rules to place these words, either before or after nouns. In this lesson, we will learn about another important feature called “concordancia del adjetivo y el sustantivo”, that is Spanish noun-adjective agreement. Do not worry, it will be easier than it sounds, thoughyou will understand everything way faster if you already know the basics aboutnoun genderand the plural form of nouns. Let’s start…

Introductory video: How touse Spanish adjectives

We will begin this lesson with a video explaining the basic rules to use Spanish adjectives. This video was recording in Spanish, but you can also activate the captions (cc) below or check the script. It includes some examples and notes that will bevery helpfulto understand more about the way adjectives work in the language.

Spanish Adjectives Gender Agreement

Spanish masculine adjectives

Most Spanish adjectives must agree in gender with the noun they modify. When describing a masculine noun like “Amigo” (friend), we must use a masculine adjective such as “Honesto” or at least a neutral like “Inteligente”. Just like with nouns, Spanish masculine adjectives usually end in the vowel -O like “Bonito” and “Creativo”. In addition, some words ending in -R will also be considered masculine adjectives, as shown here:

• El niño es bonito y gordo. (The kid is cute and chubby.)
• El auto es nuevo y espacioso. (The car is new and spacious)

Since both “Niño” and “Auto” are masculine nouns, we must make the adjectives agree with these nouns in Spanish. Otherwise, what we say may sound a bit strange.

Some examples of common masculine adjectives in Spanish are:

Afortunado (lucky), Alto (tall), Bajo (short), Bueno (Good), Estupendo (awesome), Famoso (famous), Malo (bad) and Pequeño (small)

Spanish feminine adjectives

On the other hand, when describing feminine nouns like CASA (house), we have to use a feminine adjective like BONITA (pretty) or ESPACIOSA (spacious), and not a masculine one such as BONITO or ESPACIOSO. That being said, Spanish feminine adjectives are the same words with a slight change at the end from -O to -A, e.g. “Bueno” to “Buena”, for example:

• Su novia es muy simpática. (His girlfriend is very nice.)
• ¡Gracias! La comida estuvo deliciosa. (Thank you! The food was delicious.)

Pay attention to a list of common adjectives in Spanish and check how some of them would change their gender from masculine to feminine, e.g. “Bueno” -> “Buena”. Those ending in -E generally won’t need any change to agree with nouns as they are neutral, something we will explain further later.

Know that it is possible to make some masculine adjectives feminine in Spanish by adding -A at the end when the word ends in a consonant, but not in all cases, e.g. “Trabajador/Trabajadora” (correct) and “Popular/Populara” (incorrect).Most nationalities do suffer gender changes too, including some that end in consonants like “español->española”. Read and listen to these sample sentences:

Spanish adjectives forboth masculine and feminine nouns

Some adjectives are used for both genders despite their ending, especially those that end in -Eor in consonants, for example: “un libro interesante”, “un examen fácil”, “un chico optimista/una chica optimista”.

Some common Spanish nouns that won’t suffer gender changes are:

Amable (kind), Difícil (difficult), Fácil (easy), Flexible, Paciente (patient), Verde (green).

Most numbers (except for the number one) will stay the same for masculine or feminine nouns, so you could say “Cuatro perros” or “Cuatro casas” and that would be totally correct. However, the number “UNO” will change to UN when used before a masculine noun as in “Un gato“, and to “UNA” before a feminine noun as in “Una amiga”. In this scenerario, UN/UNA would be used as indefinite articles.

Making Spanish adjectivesagree with plural nouns

As we mentioned above, Spanish adjectives normally have a singular and a plural form. The rules are exactly the same used toform the plural of nouns. To illustrate this, read these two sentences carefully:

• Ella es una modelo hermosa. (She is a pretty model.)
• Ellas son modelos hermosas. (They are pretty models.)

In these two examples, our goal was to make the noun “modelo” agree with the Spanish adjective “hermoso”, but since “Modelo” is always used in masculine form, the subject “Ella” or “Ellas” tell us we need a feminine adjective. As for the plural form, the subject of the sentence tells us if we are talking about one or many objects, and that help us decide if we must use a singular or plural adjective too. Notice that all the words, including the verb SER, will change so that there is actual noun-adjective agreement in Spanish and to have a fully functional sentence.

Pay attention to the following group of common adjectives in Spanish and how we could form their plural in the language.

Here is a last group of sample sentences showing how we must make adjectives agree with nouns in Spanish so that our sentences are functional and truly express our thoughts:
