Introduction
Learning Spanish grammar can be challenging, especially when you encounter expressions that seem unusual at first glance. One particularly useful phrase that helps Spanish learners describe personality patterns and habitual behaviors is ser de los que. This construction allows you to express what type of person you are based on your typical actions and characteristics. Whether you’re describing yourself as someone who is always late, naturally creative, or constantly organized, understanding how to use ser de los que will significantly enhance your ability to communicate about personality traits and behavioral patterns in Spanish. In this article, we’ll explore everything you need to know about this important grammatical structure.
What Does Ser de los Que Mean?
Ser de los que is a Spanish expression that literally translates to being one of those who, or being the type of person who. This phrase is incredibly versatile and is used frequently in everyday Spanish conversation. The structure allows you to categorize yourself or others into a group of people who share a common characteristic, habit, or behavioral pattern.
The expression works by combining the verb ser (to be) with the preposition de and the article los que (those who). When you use ser de los que, you’re essentially saying you belong to a category of people defined by a particular behavior or trait. This is much more dynamic than simply saying you are something, because it emphasizes the action or behavior that defines you.
For example, if you say Soy de los que llega siempre tarde, you’re not just saying you are late sometimes, but rather that your characteristic as a person is being someone who is habitually late. It’s a way of identifying with a group and the behaviors that group exhibits.
The Basic Structure of Ser de los Que
Understanding the structure of ser de los que is essential for using it correctly. Let’s break down the components:
The formula is simple: [Subject] + ser + de los que + [verb in present tense]. The verb that follows de los que should typically be in the present indicative tense, as you’re describing a habitual action or characteristic that defines who you are.
For example:
Yo soy de los que madruga cada mañana.
(I am the type of person who wakes up early every morning.)
Ella es de los que siempre dice la verdad.
(She is the type of person who always tells the truth.)
Nosotros somos de los que prefieren la playa al montaña.
(We are the type of people who prefer the beach to the mountains.)
The subject pronoun can be omitted since the verb conjugation makes it clear who you’re talking about. Additionally, the verb following de los que should agree with the plural form because los que is plural, even if you’re talking about a singular person.
Gender and Number Agreement
One important aspect of using ser de los que correctly involves understanding gender and number agreement. Since los que is masculine plural, the article and article forms must remain consistent. However, when you’re talking about a single female, you might use ser de las que instead.
Let’s look at some examples:
For males or mixed groups: soy de los que, eres de los que, es de los que
For females specifically: soy de las que, eres de las que, es de las que
Here are practical examples:
Yo soy de los que trabaja duro para lograr sus objetivos.
(I am someone who works hard to achieve their goals.)
Ella es de las que no teme expresar su opinión.
(She is someone who is not afraid to express her opinion.)
Ellos son de los que disfrutan de una buena película en casa.
(They are the type of people who enjoy a good movie at home.)
Using the correct gender form shows attention to grammatical detail and helps your Spanish sound more natural to native speakers.
Tense Usage with Ser de los Que
While the present tense is most common after ser de los que, you can also use other tenses depending on what you want to express. Let’s explore different tense combinations:

The present tense is the standard choice when describing habitual or characteristic behaviors. This is what you’ll use most frequently:

Preterite or Past Tense
You can use the past tense when describing something that characterized you in a specific period, though this is less common:

Common Mistakes to Avoid
When learning to use ser de los que, there are several common errors that learners make. Understanding these mistakes will help you avoid them:

Another mistake is using the wrong gender form. Pay attention to whether you’re talking about a male, female, or group:

Additionally, some learners forget to use the preposition de, which is essential to the structure:
Incorrect: Soy los que siempre llega temprano.
Correct: Soy de los que siempre llega temprano.
Cultural Nuances and Native Usage
Native Spanish speakers use ser de los que frequently in both casual conversations and more formal contexts. The expression is versatile and allows for creative and nuanced descriptions of personality and behavior. In Spanish-speaking cultures, describing oneself through action and behavior is often seen as more authentic than listing adjectives.
You’ll hear this expression in interviews, conversations between friends, family discussions, and even in media. It’s a particularly Spanish way of expressing identity, as it emphasizes what you do rather than just who you are in static terms.
Understanding this cultural preference for action-based descriptions will help you communicate more naturally with Spanish speakers and better appreciate Spanish literature, films, and conversations.
Exercises to Practice Ser de los Que
To solidify your understanding of ser de los que, try creating your own sentences. Think about your own habits and personality traits, and practice describing them using this structure. Start with simple sentences and gradually make them more complex.
