At the A1 level, 'perjudicar' might be a bit advanced, but you can understand it as a way to say 'something is bad for you.' It is like saying 'es malo para...' For example, if you want to say 'Candy is bad for teeth,' you could eventually say 'El azúcar perjudica los dientes.' At this stage, focus on the idea that this word means 'to hurt' or 'to be bad for' something's health or state. You might see it on signs or warnings. It's a regular verb, so it follows the same pattern as 'hablar.' Just remember: [Thing] + perjudica + [Other Thing]. It's a good word to know early because it appears in many health warnings you will see in Spanish-speaking countries.
At the A2 level, you can start using 'perjudicar' to talk about health and daily habits. You know more verbs now, so you can compare it to 'dañar' (to damage). While 'dañar' is for breaking things like a toy or a phone, 'perjudicar' is for things like your health or your grades. You can use it in the present tense: 'Fumar perjudica la salud' (Smoking harms health). You can also use it to talk about how things affect people by using the 'personal a': 'Esto perjudica a mi amigo.' It's a useful word for giving advice or talking about why certain habits are not good. You might also start to see it in simple news stories about the weather harming crops.
At the B1 level, 'perjudicar' becomes a key vocabulary word for discussing opinions, social issues, and more complex cause-and-effect relationships. You should be able to use it in different tenses, like the preterite ('Eso me perjudicó') or the future ('Esto nos perjudicará'). You will also encounter it in the subjunctive when expressing wishes or fears: 'No quiero que esto te perjudique.' At this level, you understand that 'perjudicar' is more than just physical damage; it’s about harming interests, reputation, or progress. It is a more formal and precise word than 'hacer daño.' You will hear it in debates, see it in newspapers, and use it to justify your opinions on topics like the environment or the economy.
At the B2 level, you are expected to use 'perjudicar' with precision in both formal and informal contexts. You should understand its nuances compared to synonyms like 'menoscabar' or 'deteriorar.' You can use it in complex sentence structures, including passive voice ('Fue perjudicado por la crisis') and conditional clauses ('Si hiciéramos eso, perjudicaríamos nuestra imagen'). You also recognize the noun form 'perjuicio' and the phrase 'daños y perjuicios' (damages). At this level, you use 'perjudicar' to discuss the impact of government policies, corporate decisions, and social trends. Your usage should reflect an understanding of how the word functions as a transitive verb with abstract objects like 'prestigio,' 'rentabilidad,' or 'bienestar.'
At the C1 level, 'perjudicar' is a word you use instinctively to articulate subtle negative impacts in professional and academic discourse. You are aware of its legal connotations and can use it in technical discussions about liability and impact assessments. You can weave it into sophisticated arguments, using it alongside adverbs that specify the degree and nature of the harm (e.g., 'perjudicar colateralmente,' 'perjudicar intrínsecamente'). You also understand how the verb interacts with different registers, knowing when to choose it over more literary terms like 'obstar' or more common ones like 'fastidiar.' Your mastery includes the ability to use 'perjudicar' in the reflexive sense to discuss self-sabotage or internal conflicts within an organization.
At the C2 level, you have a near-native grasp of 'perjudicar' and its entire word family. You can use it to discuss philosophical or highly abstract concepts, such as how a certain ideology might 'perjudicar el tejido social.' You are comfortable with its use in all literary and historical contexts. You can identify and use idiomatic expressions or rare collocations involving the word. Your understanding includes the historical evolution of the word from Latin and how its meaning has specialized over time in the Spanish legal system versus everyday speech. You can use 'perjudicar' to provide nuanced critiques of literature, art, or complex geopolitical situations, ensuring that the tone and impact of the word perfectly match the high-level discourse you are engaged in.

perjudicar in 30 Seconds

  • Perjudicar is a Spanish verb meaning to harm or cause damage, especially to abstract concepts like health or reputation.
  • It is a regular -ar verb, making it easy to conjugate in all tenses for intermediate learners.
  • The word is frequently found in formal warnings, legal documents, and professional discussions about negative impacts.
  • It is the direct antonym of 'beneficiar' and is more formal than the common phrase 'hacer daño'.

The Spanish verb perjudicar is a versatile and essential term used to describe the act of causing harm, damage, or a detrimental effect on someone or something. While it can often be translated as 'to harm' or 'to damage,' it carries a specific nuance of undermining interests, health, or reputation. It is a word that bridges the gap between everyday physical damage and more abstract, formal, or legal consequences. Understanding this word is crucial for B1 learners because it allows for more sophisticated expressions of cause and effect beyond the simple 'es malo' (it is bad).

Formal Contexts
In legal or business settings, 'perjudicar' is the standard way to talk about actions that undermine a contract, a company's interests, or a person's rights. It is less about physical breaking and more about the erosion of value or standing.

Esa decisión podría perjudicar seriamente nuestra reputación en el mercado internacional.

In medical or health contexts, the word is ubiquitous. You will see it on cigarette packages, in nutritional guides, and in doctor's advice. It specifically points to the negative physiological impact of habits or substances. Unlike 'herir' (to wound), 'perjudicar' implies a process of degradation or a negative outcome resulting from a specific cause.

Reputational Harm
When someone speaks ill of another person, they are 'perjudicando' that person's image. This usage is common in social and professional circles where one's 'nombre' (name) is at stake.

Los rumores falsos terminaron por perjudicar su carrera política de manera irreversible.

Furthermore, 'perjudicar' is often contrasted with 'beneficiar' (to benefit). This binary is helpful for learners to remember. If something doesn't help you, it might be 'perjudicando' you. In economic terms, inflation 'perjudica' the middle class, while certain tax breaks might 'beneficiar' them. This word is essential for discussing social issues and policy impacts.

Environmental Impact
When discussing ecology, we use this verb to describe how pollution or deforestation harms local ecosystems. It provides a more academic and precise tone than simply saying 'es malo para la naturaleza'.

El vertido de químicos en el río va a perjudicar a todas las especies locales.

No quiero que mis acciones te perjudiquen en el futuro; prefiero ser honesto ahora.

Finally, the word is also used in the reflexive form 'perjudicarse', though less common. This implies harming oneself through one's own actions, such as 'perjudicarse a sí mismo' by not studying or by making poor health choices. In summary, 'perjudicar' is your go-to verb for describing negative impacts across health, law, business, and social standing, providing a level of precision that marks a transition from basic to intermediate Spanish proficiency.

Using 'perjudicar' correctly requires an understanding of its conjugation as a regular -ar verb and its role as a transitive verb. It follows the standard pattern of verbs like 'hablar' or 'cantar', making it relatively easy to conjugate once you know the stem. However, the complexity lies in identifying what exactly is being harmed and how to structure the sentence to reflect that impact clearly.

Direct Object Usage
The most common structure is [Subject] + [Verb] + [Direct Object]. For example, 'El tabaco perjudica la salud'. Here, 'el tabaco' is the cause, and 'la salud' is the entity receiving the harm.

Las nuevas leyes podrían perjudicar a los pequeños empresarios del país.

When the object being harmed is a person, Spanish requires the 'personal a'. This is a common point of error for English speakers. You don't just 'perjudicar Juan'; you 'perjudicar a Juan'. This distinction is vital for grammatical accuracy and natural-sounding speech.

Using Adverbs for Intensity
To describe the extent of the harm, 'perjudicar' is often paired with adverbs like 'seriamente' (seriously), 'gravemente' (gravely), or 'notablemente' (notably). This adds depth to your descriptions of negative impact.

La falta de lluvia ha perjudicado notablemente las cosechas de este año.

The subjunctive mood is also frequently used with 'perjudicar', especially when expressing fear, doubt, or suggestions about potential harm. Phrases like 'No quiero que esto te perjudique' (I don't want this to harm you) are common in interpersonal communication. This requires the learner to be comfortable with the change from 'perjudica' to 'perjudique'.

Tense Variations
Whether in the past (perjudicó), present (perjudica), or future (perjudicará), the verb maintains its core meaning of negative impact. The preterite is used for specific instances of harm, while the imperfect is used for ongoing harmful situations.

Si sigues gritando, solo vas a perjudicar tu propia imagen ante el jefe.

El escándalo perjudicó las posibilidades de que el equipo ganara el campeonato.

In more complex sentences, 'perjudicar' can be part of a causal chain. For instance, 'La sequía perjudica la agricultura, lo cual a su vez perjudica la economía nacional'. This shows the ripple effect of harm. Mastery of this verb allows you to construct these logical sequences, which are essential for academic writing and professional discourse in Spanish.

You will encounter 'perjudicar' in a variety of real-world scenarios, ranging from formal news broadcasts to daily conversations about health and lifestyle. It is a word that carries an air of authority and seriousness, making it the preferred choice when the speaker wants to emphasize the gravity of a negative situation. Unlike more colloquial terms, 'perjudicar' sounds objective and considered.

News and Media
In news headlines, 'perjudicar' is frequently used to discuss the impact of economic policies, international conflicts, or environmental disasters. You might hear: 'La subida de impuestos perjudicará al consumo'.

El cierre de la frontera ha perjudicado el comercio entre ambos países.

In the workplace, managers and colleagues use it to discuss project risks or professional behavior. It is common in performance reviews or strategic meetings where potential downsides are analyzed. It is a professional way to say 'this is going to hurt us'.

Health Warnings
Almost every Spanish-speaking country mandates health warnings on products like alcohol and tobacco. The phrase 'Fumar perjudica gravemente su salud' is iconic and found on millions of cigarette packs.

Beber en exceso puede perjudicar el funcionamiento del hígado.

In educational settings, teachers might use 'perjudicar' to warn students about the consequences of their actions. For example, 'Faltar a clase perjudicará tus calificaciones'. It is a way of establishing a clear link between a behavior and a negative outcome. Similarly, in social situations, friends might use it to offer advice: 'No digas eso, te puede perjudicar'.

Legal and Official Documents
Contracts often include clauses about not performing actions that 'perjudiquen' the interests of the other party. It is a key term in the language of agreements and liabilities.

Cualquier alteración del contrato que perjudique al arrendador será nula.

El ruido constante de la construcción está perjudicando el descanso de los vecinos.

Whether you are reading a newspaper in Madrid, watching a soap opera in Mexico City, or reviewing a contract in Buenos Aires, 'perjudicar' will appear as the definitive way to talk about negative impacts. Its frequency in high-stakes communication makes it an indispensable part of your Spanish vocabulary.

Even intermediate learners often stumble when using 'perjudicar' due to its similarity to other words and its specific grammatical requirements. Avoiding these common pitfalls will make your Spanish sound much more professional and accurate. The most frequent errors involve confusion with cognates, incorrect preposition use, and overlapping with similar verbs like 'dañar'.

Confusion with 'Prejuzgar'
Because 'perjudicar' looks like the English word 'prejudice', many learners use it to mean 'to have a prejudice against someone'. However, the correct word for that is 'prejuzgar'. 'Perjudicar' is the *result* of harm, not the *thought* behind it.

Incorrecto: No me perjudiques antes de conocerme. (Meaning: Don't harm me before knowing me - weird context). Correcto: No me prejuzgues.

Another common mistake is forgetting the 'personal a'. In Spanish, when the direct object of a verb is a specific person or pet, you must use 'a'. Many English speakers say 'Esto perjudica mi hermano' instead of 'Esto perjudica a mi hermano'. This small word is essential for grammatical correctness.

Overusing 'Dañar'
While 'dañar' and 'perjudicar' are synonyms, 'dañar' is often used for physical objects (like a car or a phone), while 'perjudicar' is for abstract things (like health, economy, or reputation). Using 'dañar' for a legal right sounds slightly less natural than using 'perjudicar'.

Incorrecto: El humo daña a la economía. (It's okay, but 'perjudica' is much more common in this context).

Learners also sometimes confuse 'perjudicar' with 'perjurrar' (to perjure oneself). While both are formal and start similarly, they have no semantic connection. Additionally, some students try to use 'perjudicar' as an intransitive verb (e.g., 'Esto perjudica mucho'), but in Spanish, it usually needs an object to be 'perjudicado'.

Spelling Errors
Watch out for the 'j'. Since it sounds like an 'h' or a 'kh', some learners might try to spell it with a 'g' (pergudicar), which is incorrect. Always use the 'j'.

Recuerda: El verbo es perjudicar, con J de 'jamón'.

No confundas perjudicar (harm) con perjudicado (the victim/the harmed party).

By being aware of these nuances—the 'personal a', the distinction from 'prejuzgar', and the proper spelling—you will avoid the most common traps that catch English speakers. This will help you use the word with the confidence and precision of a native speaker.

While 'perjudicar' is a powerful word, Spanish offers a variety of synonyms and related terms that can help you express different shades of harm or damage. Choosing the right one depends on the context—whether it's physical, emotional, or institutional. Understanding these alternatives will significantly expand your descriptive range.

Dañar vs. Perjudicar
'Dañar' is more general and often applies to physical objects (e.g., 'dañar el motor'). 'Perjudicar' is preferred for abstract concepts like 'intereses', 'salud', or 'derechos'.
Lastimar vs. Perjudicar
'Lastimar' is usually used for physical pain or hurting someone's feelings. You wouldn't say a law 'lastima' the economy; you would say it 'perjudica' the economy.
Menoscabar
This is a more formal and literary synonym. it means to lessen or diminish the value or prestige of something. It is often used in legal and academic writing.

Sus comentarios intentan menoscabar mi autoridad frente al grupo.

Other alternatives include 'afectar negativamente' (to affect negatively), which is very common in news and reports. 'Deteriorar' is used when something is slowly getting worse, like health or a relationship. 'Damnificar' is a very formal term, often used for victims of natural disasters (los damnificados).

Deteriorar
Used for the gradual worsening of a condition. 'El clima extremo ha deteriorado las carreteras'.

La falta de mantenimiento terminó por deteriorar el edificio histórico.

On the opposite side, 'beneficiar', 'favorecer', and 'ayudar' are the primary antonyms. In a balanced argument, you might use both: 'Esta medida beneficia a los ricos pero perjudica a los pobres'. This contrast is a hallmark of high-level Spanish debate and analysis.

Afectar negativamente
A very common phrase in technical reports. It is essentially a synonym for 'perjudicar' but sounds slightly more neutral.

La inflación afecta negativamente al poder adquisitivo de las familias.

No queremos comprometer nuestra posición por una mala decisión.

By mastering these nuances, you can tailor your language to the specific type of harm you wish to describe, making your Spanish more expressive, precise, and professional.

Challenge

Write three sentences about things that 'perjudican' the environment, using three different tenses (present, past, future).

Word Origin

From the Latin verb 'praeiudicare', which means 'to judge beforehand' or 'to decide in advance'. Over time, the meaning shifted from a mental judgment to the actual negative consequence or harm resulting from an action.

Original meaning: To judge beforehand (pre-judge).

Romance (Latin root).

Cultural Context

Be careful when using it to describe people; ensure you are talking about their interests or health, not making a personal attack.

English speakers often use 'harm' or 'hurt', but 'perjudicar' sounds more like 'detrimental' or 'to be to the prejudice of' in formal English.

Health warnings on Marlboro packs in Spain: 'Fumar perjudica gravemente su salud'. Legal codes in Mexico and Colombia regarding 'daños y perjuicios'. News reports on the 'crisis económica' and how it 'perjudica' the middle class.
