‘Ser’ Adjectives and How to Use Them in Spanish Sentences
Learning the different forms of the verb ser, Spanish for “to be,” is one of the more challenging aspects of learning the language. In English, conjugating the verb “to be” requires memorizing all of the irregular forms of the verb; the same case applies to Spanish. Unfortunately, most of these conjugations have no shortcut or easy way to learn them (with a few exceptions). On top of that, learning between ser and estar can also take some time! If you want to learn to conjugate ser, you’ll have to put in the legwork. So let’s slip into our running shoes and start learning the many ways you can conjugate ser in Spanish!
Ser Conjugation Tables
Let’s check out some conjugation tables for the different situations you’ll be using ser in.

How do Adjectives work in Spanish?
Types of Adjectives
In Spanish there are several kinds of adjectives that interact with the verb ser in different ways. Let’s take a look at them.
Possessive and Demonstrative Adjectives
Possessive
First-person singular: mi, mío, mis, míos
First-person plural: nuestro, nuestra, nuestros, nuestras
Second-person singular: tu, su, tuyo, tus, sus, tuyos, suyos
Second-person plural: su, sus
Third-person singular: su, sus
Third-person plural: su, sus
Demonstrative
Describing proximity: ese, esa, esos, esas, este, esta, estos, estas
Describing distance: aquel, aquella, aquellos, aquellas
How to Use Possessive and Demonstrative Adjectives With Ser
The possessive adjectives mío, míos, tuyo, tuyos, and suyos go after the verb ser.
- El carro azul es mío. — The blue car is mine.
Alternatively, mi, mis, tu, su, and sus go before the verb ser.
- Mi carro es azul. — My car is blue.
Nuestro, nuestra, nuestros, and nuestras can go either before or after the verb ser.
- Nuestros amigos son geniales. — Our friends are great.
- Esas sillas son nuestras. — Those chairs are ours.
Limiting Adjectives
Limiting adjectives, or adjetivos indefinidos are used to describe subjective or abstract orders of magnitude.
| Spanish Adjective | Translation |
| mucho | A lot |
| poco | A little |
| alguno | some |
| bastante | many |
| ninguno | none |
| suficiente | enough |
| varios | various |
| cuanto | As much as / as soon as |
| demasiado | Too much / too many |
| cierto | certain (number) |
| cualquier | any |
| demás | others |
| cada | every |
We’ll talk about how placement affects the meaning of some verbs later, so stay tuned! Let’s look at some examples of these adjectives with the verb ser.
La época medieval fue hace mucho tiempo. — The middle ages were a long time ago.
Mi fiesta de cumpleaños fue hace algunos meses. — My birthday party was some months ago.
Una hamburguesa es suficiente para mí. — One hamburger is enough for me.
Los chequeos médicos de Juan son cada dos semanas. — Juan’s medical check-ups are every two weeks.
Numeral Adjectives
We’ve covered this topic in a previous blog post, so for these adjectives we’ll get right to the examples. If you don’t know the difference between ordinal and cardinal numbers, or how to say them in Spanish, I highly recommend you take a couple of minutes to read through our Numbers in Spanish post first.
Mi hermana es cuatro años menor que yo. — My sister is four years younger than me.
Mañana es el décimo aniversario de mi empresa. — Tomorrow is my company’s tenth anniversary.
El nuevo edificio es diez veces más grande que el anterior. — The new building is ten times bigger than the last one.
Esta es la tercera vez que pierdo mis llaves. — This is the third time I lose my keys.
Placing Adjectives Before Nouns
Most of the time, you’ll find the adjective after the noun it’s describing. Let’s look at a previous example:
Me cantó una canción triste. – She sang me a sad song.
Here, the adjective triste goes right after the noun canción. This is the most common sentence structure you’ll find when speaking Spanish. So what’s the difference when you put the adjective before the noun?
The answer is emphasis.
By putting the adjective before the noun, you will give more heft to the description of your noun. This is often used in poetry, but it’s not recommended to speak like that or use it often because it’s not a structure found naturally in Spanish. Let’s try it out.
Me cantó una canción triste — Me cantó una triste canción.
Can you feel the difference? The second sentence has a little more heft to it. Triste is emphasized by subverting the expectation of a noun with the adjective, so the unexpected word is easily noticed by the listener.
Adjective Positioning Can Change a Word’s Meaning!
Instead of adding emphasis, some words will change meaning when they are placed before the verb. These exceptions are common in Spanish and won’t sound strange to the common speaker. Here’s a list of common examples for you to learn!
| Adjective | Meaning before noun | Meaning after noun |
| antiguo | former | old |
| cierto | certain | true |
| curioso | interesting | feeling curiosity |
| gran (grande) | great | big |
| pobre | inspiring pain or suffering | lacking money or resources |
| próximo | upcoming | next to |
| puro | simple | pure |
| solo | single (number) | lonely |
| simple | modest | lacking |
| único | only | unique |
| verdadero | real | true |
| nuevo | new (to the user) | brand new |
| diferente | distinct | not the same |
| vario | several | varied |
