What are complaint verbs in Spanish?
Complaint verbs are verbs used to express annoyance, dissatisfaction, or to report problems. In Spanish, many of these verbs can be used both transitively and reflexively, and the meaning often changes depending on the structure. Common verbs include quejar (usually used reflexively as quejarse), lamentar, molestar, fastidiar, enojar, volver loco, and cansar.
Why reflexive forms matter
Reflexive forms are important because they change the focus of the sentence. With complaint verbs, a reflexive verb often emphasizes the experiencer of the feeling. For example, quejar is rarely used without the reflexive pronoun, while molestar can be used both ways with different meanings. Learning the reflexive patterns helps you express who feels annoyed and who causes annoyance.
Common verbs and their reflexive vs non-reflexive uses
Below are common complaint verbs with explanations about reflexive and non-reflexive usage, followed by example sentences. The first appearance of each key Spanish verb is bolded; later references use italics where appropriate.
Quejarse de
Quejarse is the textbook verb for complaining. It is always reflexive: one complains oneself. The preposition that follows is typically de, meaning about. Use quejarse de to state the topic of the complaint.
Example:
Me quejé de el ruido en el bar.
Often you will see the contracted form del: Me quejé del ruido en el bar.
Lamentar
Lamentar expresses regret or sorrow. It is not reflexive when saying that something is regrettable, but it can be followed by que to introduce a clause. Use it for formal complaints or regrets rather than casual annoyance.
Example:
Lamentamos el mal servicio que recibiste.
Lamento que no puedas venir.
Molestar
Molestar means to bother or disturb. When used non-reflexively, it emphasizes the cause and the person bothered is marked with an indirect object pronoun (me, te, le, nos, os, les). When used reflexively as molestarse, it emphasizes the person experiencing annoyance or that they take offense.
Example non-reflexive:
La música me molesta.
Here, the focus is on the cause: the music bothers me.
Example reflexive:
Se molestó por el comentario.
He took offense at the comment; emphasis on his reaction.
Fastidiar and enfadar
Fastidiar and enfadar are similar to molestar but often stronger. Fastidiar often carries a tone of irritation, while enfadar implies anger. Both are commonly used with indirect object pronouns to indicate who is affected.
Example:
La cola para pagar me fastidió mucho.
El ruido en la oficina le enfadó.
Volver loco and cansar
Volver loco is an idiomatic way to say something drives someone crazy, sometimes in annoyance. Cansar (to tire) can also express irritation: something tires someone out or wears on their patience. Use indirect object pronouns to mark the affected person.
Example:
El tráfico me vuelve loco cada mañana.
Las reuniones largas nos cansan.
Prepositions commonly used with complaint verbs
Prepositions are crucial because they link the verb with the cause, topic, or agent of the complaint. The most common prepositions with complaint verbs are de, por, con, and a. Each carries a subtle difference in meaning.
De — about or concerning
De is used to indicate the subject or topic of the complaint after verbs like quejarse, lamentar, and sometimes molestar. It answers the question about what the complaint is.
Examples:
Se quejaron de la comida.
Me quejo de que haya tanto ruido.
Por — because of or due to
Por indicates cause or reason. Use it when the complaint is explaining the reason for annoyance or offense. It often appears with verbs like molestar, enfadar, and fastidiar.
Examples:
Se enfadó por el retraso del vuelo.
Me molesta por su falta de puntualidad.
Con — with, referring to people or things
Con can point to the person or thing you have an issue with. It is used after verbs such as tener problema or when specifying interpersonal friction.
Examples:
Tengo un problema con el vecino.
Ella está enfadada con su colega.
A — indicates direction of emotion
A is used less often but commonly appears with verbs that take indirect objects to mark the person who receives the emotion. For example, expressions like Me molesta a mí are possible for emphasis though less common than indirect pronouns.
Example:
Eso le molesta a María.
Indirect object pronouns and emphasis
Many complaint verbs require indirect object pronouns to indicate who is affected. The pronouns are me, te, le, nos, os, les. They appear before conjugated verbs or attached to infinitives and gerunds.
Example with pronouns:
Me fastidia que me interrumpan.
Nos molesta el humo del cigarro.
For clarity or emphasis, Spanish often uses the stressed prepositional phrase a + name or a + pronoun with le/les. This is called the clarifying a or prepositional complement.
Example:
Le molesta a Juan que llegues tarde.
Les enfada a mis padres el ruido.
Leísmo and regional variation
Note on usage: In some regions, especially parts of Spain, le is used instead of lo or la for direct objects referring to people. This leísmo can affect how speakers express complaints. If you learn Latin American Spanish, you will mostly hear lo and la for direct objects and le reserved for indirect objects.
Structures to express complaints: step-by-step
Below are patterns that you can use to construct complaint sentences. Start with the person affected, then the verb, then the preposition and the reason or topic.
Structure 1: Person + indirect object pronoun + verb + preposition + cause
Me + molesta + por + la música alta.
Me molesta por la música alta.
Structure 2: Reflexive verb + preposition + topic + optional clarifying a + person
Se queja de + el precio + a + la administración.
Se queja del precio a la administración.
Structure 3: Verb + que + subordinate clause for complex complaints
Lamento que + no + podamos + ayudar.
Lamento que no puedas venir.
Structure 4: Emphatic construction with a + name for clarification
Le enfada a Marta que + tú + no + avises.
Le enfada a Marta que no avises.
Examples in context
Here are realistic conversational lines showing how native speakers express complaints. Notice reflexive choice, preposition use, and pronoun placement.
Example 1:
No soporto más este ruido. Me vuelvo loco con la construcción de al lado.
Example 2:
Se quejan del servicio cada vez que vienen. Se quejan de la lentitud y de la falta de atención.
Example 3:
¿Por qué te molestas por cosas tan pequeñas? No vale la pena.
Example 4:
Nos fastidió mucho que cancelaran la reunión sin avisar.
Example 5:
Le molestó a Ana que llegáramos tarde; a ella le gusta ser puntual.
Politeness and register
When complaining in Spanish, tone and word choice affect politeness. For formal or polite complaints, use verbs like lamentar and passive or impersonal constructions: Lamentamos informarle que, or Nos gustaría señalar que. For informal complaints among friends, verbs like quejarse, molestar, and idioms such as Me vuelve loco work well.
Cultural note: Direct confrontation is less common in some Spanish-speaking cultures, so softening language with por favor, quizás, or a conditional (Me gustaría que) can make a complaint more acceptable in customer service or professional settings.
Common mistakes and how to avoid them
Beginners often omit the indirect object pronoun or mix up prepositions. Remember that many complaint verbs need me/te/le/nos/os/les to indicate who is affected. Also be careful with prepositions: quejarse requires de for the topic, while molestar and enfadar commonly use por for cause or con to indicate the person you are upset with.
Avoid literal translations from English that use complain to with. In Spanish you will say Me quejo de or Me quejo con alguien when meaning to complain to someone directly.
Quick reference: verbs and prepositions
Use this compact guide when composing sentences:
Quejarse de + topic
Molestar + indirect object + por + reason or Molestar con + person
Enfadar + indirect object + por + reason or Enfadarse con + person
Lamentar + noun or que + clause (more formal)
Fastidiar + indirect object + por + reason
Conclusion
Mastering complaint verbs in Spanish requires attention to reflexive forms, indirect object pronouns, and the right prepositions. Use quejarse with de for topics, pair molestar and enfadar with indirect pronouns and por or con as needed, and choose formal verbs like lamentar for polite contexts. Pay attention to regional variation and soften your language for polite complaints.
