How did I select these adjectives in Spanish that Start with A

Before I dive into this list of adjectives in Spanish that start with A, I just want to provide a little basis on how I chose these particular adjectives.

When I was a senior in high school, I was given a Collins Spanish Dictionary, 2006 version, for winning the award for “Excelencia en la Lengua Hispana” (Hispanic Language Excellence.)

I adore this book and reference it all the time as I explain in my post on ways that I learn Spanish outside of the classroom. 

I have chosen this selection of adjectives from this very dictionary.

How did I choose which adjectives to include in this list?

I chose this Spanish adjectives list based on common Spanish adjectives and not-so-common ones that I have heard over the last 20 years of my professional years as a translator/researcher, and throughout my personal experiences with the Latino community and throughout my travels. 

WHAT ARE ADJECTIVES AND HOW DO THEY WORK IN SPANISH?

Let’s do a really quick Spanish grammar lesson about adjectives.

Adjectives are descriptive words that describe a noun or a noun phrase.

Here are a few example in sentences in English and the Spanish sentence translation. 

In this sentence, big is describing house. 

My brother is tall and he has a very kind personality. 
Mi hermano es alto y tiene una personalidad muy amable

In this sentence, we have two adjectives, tall and kind. Tall describes the brother, and kind describes his personality. 

Did you notice that both of the adjectives in Spanish start with an A? A lead up to this long list of Spanish adjectives that start with A!!

HOW DO SPANISH ADJECTIVES DIFFER FROM ENGLISH ADJECTIVES?

Spanish adjectives work a little differently than English adjectives. How?

Well, just like Spanish nouns agree in number and gender of the noun, most adjectives have to do the same. 

• The adjective ending for a singular, masculine noun ends in -o
• The ending for a singular, feminine form ends in -a
• The ending for a plural, masucline noun ends in -os
• The ending for a plural, feminine noun ends in -as

Let’s look at some examples:

• The tall boy. El niño alto.
• The tall girl. La niña alta.
• The tall boys. Los niños altos.
• The tall girls.Las niñas altas. 
• The tall boys and girls. Los niños altos.

While in English, tall remains the same in each sentence, in Spanish, the adjective, alto, changes to agree with the number and gender of a noun.

Thus, in most cases, adjectives that end with -o, change to an -a when they are describing a female noun. 

When the noun being described is plural, it ends in -os if describing masculine noun, or mixed gender (for example in the sentence about with girls and boys), and -as if describing plural feminine nouns (las chicas altas.)

But all adjectives don’t end with an o.

Yes, you’re right. A lot of adjectives in Spanish don’t end with an -o. So what do we do in these instances?

These adjectives keep their endings for both masculine and feminine nouns. 

There is no gender agreement, but they do change in number. Let’s take a look.

Let’s draw four adjectives from this list that do not end in O:

• Alegre – Happy
• Arrogante -Arrogant
• Artesanal -Hand-made
• Audaz– Audacious

These adjectives all have different endings. So how can we make them plural?

1. For adjectives that end in -e , add -S to the plural form.

Las mujeres alegres

The happy women.

Los hombre arrogantes
The arrogant men

2. For adjectives that end in z, replace the z with c and add -es.

Los niños audaces
The audacious boys

3. For adjectives that end in any other consonant other than z, simply add -es to the end of the word. 

Las joyas artesanales
The hand-made jewelry

I know gender and number agreement of adjectives can be quite a struggle, but the more you practice, the more natural it will become!

One of the best ways I trained myself to work on gender/number agreement was through listening to Spanish music and translating the lyrics. It all eventually just clicked.
