At the A1 level, you are just starting to express feelings and simple actions. While 'defraudar' is a bit advanced for a complete beginner, you might encounter it in simple sentences about feelings. Think of it as a more formal way to say 'to make someone sad because you didn't do what you said'. For example, if you promise to help a friend with their homework and then you don't show up, your friend might feel 'defraudado'. At this level, focus on the present tense: 'Yo no defraudo a mis amigos' (I do not let down my friends). It is important to remember the 'a' before the person you are talking about. Even though you will mostly use simpler words like 'triste' (sad) or 'mal' (bad), knowing 'defraudar' helps you understand when someone is talking about a broken promise. Remember, it's a regular -ar verb, so it follows the same patterns as 'hablar' or 'estudiar'. You can use it to talk about your family and friends in basic conversations. For example, 'Mi perro nunca me defrauda' (My dog never lets me down). This is a great way to start using more sophisticated vocabulary early on in your Spanish journey. Don't worry about the legal meanings yet; just think of it as 'failing a promise'.
As an A2 learner, you are building more complex sentences and talking about past experiences. You can start using 'defraudar' in the preterite and imperfect tenses to describe things that happened. For instance, 'La comida me defraudó' (The food disappointed me) or 'Él siempre nos defraudaba' (He always used to let us down). At this level, you should begin to see the difference between 'decepcionar' and 'defraudar'. Use 'defraudar' when you want to sound a bit more serious about a promise that wasn't kept. You might hear this word in school contexts, like when a student doesn't get the grade they expected after studying hard: 'La nota defraudó mis expectativas'. You should also be aware that this verb is used with the 'personal a' for people. Practice saying things like 'No quiero defraudar a mis padres con mis notas'. You are also starting to use pronouns, so 'No te defraudaré' (I won't let you down) is a very useful phrase to learn. This level is about expanding your emotional vocabulary beyond just 'feliz' and 'triste'. 'Defraudar' gives you a way to talk about trust and expectations, which are common topics in A2 conversations about family, hobbies, and daily life. It's a regular verb, so the conjugations are easy to remember, but the impact of the word is strong.
At the B1 level, you are expected to handle more nuanced situations and express opinions. 'Defraudar' is a key verb here because it allows you to discuss trust, social obligations, and public figures. You will often see it in news articles or hear it in debates. You should be able to use it in the subjunctive mood to express wishes or fears: 'Espero que la película no me defraude' (I hope the movie doesn't disappoint me). This is also the level where you should learn the financial meaning of the word. Phrases like 'defraudar a Hacienda' (to evade taxes) will appear in reading materials. You should understand that 'defraudar' implies a breach of a 'contract', whether that contract is legal or emotional. It’s more than just being 'bad'; it’s about not being as good as promised. In B1, you can also start using the past participle as an adjective: 'Me siento defraudado por el gobierno'. This level requires you to understand the context to know if someone is talking about a criminal act or a personal feeling. You can also use it to talk about movies, books, and sports. For example, 'El final de la novela defraudó a muchos lectores' (The end of the novel disappointed many readers). Mastering 'defraudar' at B1 shows that you can move beyond basic descriptions and into the realm of social and moral evaluation.
At the B2 level, you should have a firm grasp of the nuances between 'defraudar', 'decepcionar', 'estafar', and 'fallar'. You are expected to use 'defraudar' in more abstract and formal contexts. For example, you might discuss how a social movement 'defraudó las esperanzas de una generación' or how a company 'defraudó la confianza de sus inversores'. Your use of the subjunctive should be fluid: 'Si me hubieras dicho la verdad, no me habrías defraudado'. You should also be comfortable with the passive voice and more complex sentence structures. B2 learners should recognize 'defraudar' as a common term in legal and economic Spanish. You might read about 'fraude fiscal' and understand that the verb 'defraudar' is the action behind it. In your writing, use 'defraudar' to add weight to your arguments. Instead of saying 'The results were bad', say 'Los resultados defraudaron las expectativas de la empresa'. This sounds much more professional and precise. You should also be able to discuss the psychological impact of being 'defraudado' in more depth, perhaps in an essay or a long conversation about relationships. At this level, you are not just learning the word; you are learning how to use it to convey authority and emotional depth in both spoken and written Spanish.
At the C1 level, you are approaching near-native fluency and should be able to use 'defraudar' with all its subtle connotations. You should understand its etymological roots and how it relates to the concept of 'fraude' in various legal systems. You will encounter 'defraudar' in high-level literature, legal codes, and sophisticated editorial writing. You should be able to use it ironically or hyperbolically in conversation. For instance, 'No defraudes a la tradición y pide otra ronda' (Don't let tradition down and order another round). You should also be aware of regional variations in how the word is used, though it is generally understood the same way across the Spanish-speaking world. At C1, you should be able to analyze the difference between 'defraudar a alguien' and 'defraudar algo' (like a law or a hope) in a nuanced way. Your vocabulary should include related terms like 'defraudación' (the noun for the act of defrauding) and 'defraudador' (the person who defrauds). You should be able to use the verb in complex hypothetical situations: 'De haber sabido que me defraudarías de esa manera, nunca te habría confiado mis ahorros'. C1 is about precision, and 'defraudar' is a precise tool for describing the failure of trust and the evasion of duty. You can use it to critique political systems, artistic works, or complex human behaviors with the confidence of a native speaker.
At the C2 level, you have complete mastery of 'defraudar'. You can use it in any context, from a highly technical legal argument about tax law to a poetic description of a sunset that fails to impress. You understand the historical evolution of the word and how it has shifted from a purely legal term to a deeply emotional one. You can detect the slightest nuances in its usage in different Spanish-speaking countries—for example, how 'defraudar a Hacienda' might be a more common cultural trope in Spain than in some parts of Latin America. You should be able to use the word in sophisticated wordplay or in very formal academic writing. You can distinguish between 'defraudar' as an act of commission (doing something to cheat) and an act of omission (failing to do something expected). In a C2 level discussion, you might explore the ethics of 'defraudar' in a philosophical sense. You are also expected to know rare or archaic uses of the word if they appear in classical literature. Your mastery is such that you can choose 'defraudar' over any of its synonyms to achieve a specific rhetorical effect, knowing exactly how it will land with your audience. For a C2 learner, 'defraudar' is not just a word; it is a versatile instrument for expressing the complexities of human expectation, legal responsibility, and the inevitable gaps between the ideal and the real.

defraudar 30秒で

  • Defraudar means to disappoint or fail someone's trust and expectations deeply.
  • It is also the technical term for financial fraud and tax evasion.
  • It is a regular -ar verb, but requires the personal 'a' for people.
  • The word is stronger and more formal than the common 'decepcionar'.

The Spanish verb defraudar is a multifaceted term that occupies a unique space between emotional disappointment and legal transgression. At its core, to defraud someone in Spanish means to fail to meet the expectations, hopes, or trust that another person has placed in you. It is a word heavy with the weight of broken promises and the sting of disillusionment. While in English, the word 'defraud' is almost exclusively associated with financial crimes and trickery, the Spanish defraudar is frequently used in interpersonal relationships, professional settings, and even in the context of personal goals. Understanding this word requires recognizing that it functions as both a synonym for 'to disappoint' (decepcionar) and 'to cheat' (estafar), depending entirely on the context of the conversation.

Emotional Disappointment
This is the most common usage in daily life. When a child fails to study after promising their parents they would, or when a friend reveals a secret, they are said to 'defraudar' the trust or expectations of others. It implies a moral or emotional failure rather than a physical one.

Siento haberte fallado; no era mi intención defraudar tu confianza en un momento tan importante para nosotros.

Legal and Financial Context
In a more formal or criminal sense, 'defraudar' refers to the act of evading taxes or committing fraud against the state or a company. The phrase 'defraudar a Hacienda' (to defraud the tax office) is a common headline in Spanish news, referring to tax evasion. Here, the 'expectation' being broken is the legal obligation to contribute to the public purse.

In literature and formal rhetoric, defraudar is used to describe the failure of abstract concepts. For example, a political reform might 'defraudar' the hopes of a nation, or a much-anticipated film might 'defraudar' the expectations of the critics. It is a verb that demands a subject capable of holding expectations and an object (the person or thing) that fails to fulfill them. Because it originates from the Latin 'fraudare', it maintains a sense of 'depriving' someone of what they were rightfully expecting to receive, whether that is a monetary return or an emotional response. When you use this word, you are highlighting the gap between what was anticipated and the reality that followed.

La nueva ley ha terminado por defraudar a los ciudadanos que esperaban un cambio real en el sistema educativo.

Professional Usage
In the workplace, if an employee does not perform at the level promised during an interview, the manager might feel 'defraudado'. It suggests that the 'investment' of trust or resources in that person has not yielded the expected results.

Culturally, the concept of 'no defraudar' is deeply tied to the Spanish value of 'palabra de honor' (word of honor). To fail someone is not just a mistake; it is often seen as a character flaw. This is why the word carries more weight than the English 'to disappoint'. If you disappoint someone, they might be sad; if you 'defraudar' them, they feel cheated or let down in a more fundamental way. It implies a breach of a social or personal contract. Whether you are talking about a football team losing a championship match or a politician failing to lower taxes, 'defraudar' is the go-to verb for expressing that the reality has fallen painfully short of the promise.

El delantero estrella no quiso defraudar a su afición y marcó el gol de la victoria en el último minuto.

Espero que este libro no te llegue a defraudar; he puesto mucho esfuerzo en cada capítulo.

Using defraudar correctly involves understanding its grammatical structure and the nuances of the object it acts upon. As a regular '-ar' verb, its conjugation is straightforward, but its application requires care, especially regarding the 'personal a' and the difference between its emotional and financial meanings. When you are expressing disappointment, the verb usually takes a direct object—the person who is being let down. For instance, 'No quiero defraudarte' (I don't want to disappoint you). Here, the pronoun 'te' represents the person whose expectations are at risk. If you use a noun instead of a pronoun, you must include 'a': 'No quiero defraudar a mi familia'.

Transitive Usage
In most cases, 'defraudar' is transitive, meaning it needs an object. You are always disappointing someone or something (like an expectation). You cannot simply say 'Yo defraudo' without context, as it would leave the listener wondering who or what was let down.

La película prometía mucho en el tráiler, pero terminó por defraudar a toda la audiencia.

The 'Expectations' Object
Often, the object isn't a person but an abstract concept like 'expectativas' (expectations), 'esperanzas' (hopes), or 'confianza' (trust). In these cases, the verb highlights the failure to reach a specific standard. 'Defraudar las expectativas' is a very common colocation in both formal and informal Spanish.

In the passive voice or as a past participle used as an adjective, 'defraudado' describes the state of the person who has been let down. 'Me siento defraudado' (I feel disappointed/let down) is a powerful way to express hurt or betrayal. This usage is common in personal arguments or when discussing public figures. Note that 'defraudado' is stronger than 'decepcionado'. If you say 'estoy decepcionado', you might just be sad; if you say 'me siento defraudado', you are implying that the other person had a duty or a promise that they failed to keep. It carries a subtle hint of moral judgment.

Si no vienes a la fiesta, vas a defraudar a cumpleañero, que te espera con ilusión.

Reflexive Potential
While less common, one can 'defraudarse a sí mismo' (to let oneself down). This is used in psychological contexts or self-reflection when a person fails to live up to their own internal standards or goals.

Contextual clues are vital for distinguishing between financial fraud and emotional disappointment. If the sentence involves 'dinero', 'impuestos', 'Hacienda', or 'cuentas', you are looking at the financial definition. If it involves 'amigos', 'padres', 'expectativas', or 'promesas', it is the emotional definition. In professional writing, such as business reports, 'defraudar' might refer to a product failing to meet market expectations. In all these cases, the verb maintains its core identity: a bridge between a high expectation and a lower reality. Mastering its use allows you to express complex feelings of betrayal and unmet standards with precision.

No podemos defraudar a los clientes que han confiado en nuestra marca durante años.

El político fue acusado de defraudar millones de euros a través de empresas fantasma.

The word defraudar resonates through various layers of Spanish-speaking society, from the high-stakes world of national politics to the intimate conversations of a family dinner table. If you turn on the news in Spain or Latin America, you are highly likely to hear this verb in the context of corruption scandals. Journalists use it to describe public officials who have 'defraudado la confianza del pueblo' (disappointed the people's trust) or, more literally, those who have 'defraudado fondos públicos' (misappropriated public funds). In this sphere, the word carries a heavy moral and legal weight, signaling a betrayal of the social contract that binds a leader to their citizens.

In Sports Media
Spanish sports commentary is another rich source for this word. When a top-tier team like Real Madrid or FC Barcelona loses to a much weaker opponent, commentators will say they have 'defraudado a su afición'. It captures the collective sense of letdown felt by thousands of fans who expected a victory. It’s not just about losing; it’s about failing to perform at the expected level of excellence.

La prensa deportiva afirma que el equipo nacional ha vuelto a defraudar en una cita mundialista.

In Telenovelas and Drama
The emotional resonance of 'defraudar' makes it a staple of Spanish-language television dramas. Characters often cry out, '¡Me has defraudado!' during climactic scenes of betrayal. In these contexts, it usually refers to a breach of romantic or familial loyalty. It is more dramatic than 'me has decepcionado' because it implies that the speaker had invested a significant amount of faith in the other person.

In the academic and professional world, you will encounter 'defraudar' in critiques and reviews. If a scientific study doesn't produce the results its hypothesis suggested, or if a new technology fails to solve the problem it was designed for, experts might say it has 'defraudado las expectativas iniciales'. This usage is formal and precise, focusing on the gap between theoretical potential and practical reality. Similarly, in legal documents, 'defraudar' is the technical term for specific types of fraud involving deception for financial gain. Whether in a courtroom or a laboratory, the word serves to mark the distance between what was promised and what was delivered.

El abogado argumentó que su cliente nunca tuvo la intención de defraudar a sus socios comerciales.

In Daily Conversation
In casual settings, friends might use it more lightly, though it still retains a bit of its serious edge. 'No me defraudes con la cena, ¡tengo mucha hambre!' (Don't let me down with dinner; I'm very hungry!) uses the word hyperbolically to emphasize how much the speaker is looking forward to the meal.

Ultimately, you hear 'defraudar' whenever there is a significant emotional or financial stake involved. It is a word of accountability. When someone uses it, they are not just expressing a feeling; they are making a claim about a failure of duty or trust. From the shouting of a football stadium to the whispered confessions of a couple, 'defraudar' is the linguistic tool Spanish speakers use to navigate the painful reality of human and institutional fallibility. It is a word that demands attention because it usually signals that something important has gone wrong.

Aunque el final de la serie fue polémico, no se puede decir que llegara a defraudar a los fans más leales.

Prometió que llamaría todos los días, pero pronto empezó a defraudar esa promesa con su silencio.

One of the most frequent hurdles for English speakers learning defraudar is the 'false friend' trap. In English, 'to defraud' is almost exclusively a legal term referring to financial deception or theft. If you tell an English speaker, 'You defrauded me,' they will likely think you are accusing them of stealing your money through a scam. However, in Spanish, defraudar is very commonly used to mean 'to disappoint' or 'to let down' in an emotional sense. A common mistake is being afraid to use 'defraudar' in personal contexts, opting instead for the weaker 'decepcionar'. While 'decepcionar' is correct, using 'defraudar' can convey a deeper sense of broken trust that is often more appropriate for the situation.

The Missing 'Personal A'
Because 'defraudar' often takes a person as its object, many learners forget the 'personal a'. Saying 'Defraudé mi padre' is incorrect; it must be 'Defraudé a mi padre'. This is a foundational rule in Spanish grammar that applies to all verbs when the direct object is a specific person or pet.

Muchos estudiantes olvidan incluir la preposición 'a' cuando dicen que no quieren defraudar a sus maestros.

Confusing with 'Estafar'
In financial contexts, learners often confuse 'defraudar' with 'estafar'. While they are related, 'estafar' usually implies a more active, calculated scam or 'swindling' of an individual. 'Defraudar' is more commonly used for systemic fraud, such as tax evasion or failing to fulfill a large-scale contractual obligation. 'Estafó a la anciana' (He swindled the old lady) vs. 'Defraudó a Hacienda' (He defrauded the tax office).

Another common error is misapplying the preposition that follows the past participle 'defraudado'. In English, we say 'disappointed with' or 'disappointed in'. In Spanish, when using 'defraudado' as an adjective, you should use 'con' or 'por'. For example, 'Estoy defraudado con los resultados' or 'Me siento defraudado por su actitud'. Using 'de' (e.g., 'defraudado de ti') is less common and can sometimes sound unnatural depending on the region. Pay attention to how native speakers link the feeling to the cause.

Es un error común pensar que defraudar solo se usa para crímenes de dinero; su uso emocional es vital.

Overusing the Verb
Sometimes learners use 'defraudar' for minor inconveniences. If a restaurant is out of your favorite dish, it's probably not 'defraudando' you; it's just 'una lástima' (a pity). Save 'defraudar' for cases where there was a genuine expectation or promise that was broken. Overusing it can make your speech sound overly dramatic or accusatory.

Lastly, be careful with the word 'fraude'. While 'defraudar' is the verb, 'fraude' is the noun. However, 'decepción' is the noun for emotional disappointment. You wouldn't usually say 'fue un fraude' to mean 'it was a disappointment' unless you mean it was a literal scam or a complete sham. If a concert was just bad, it was 'una decepción'. If the concert didn't even happen and the organizer took the money, then it was 'un fraude'. Distinguishing between the emotional and legal nouns will help you avoid sounding like you're accusing everyone of being a criminal!

No confundas 'un fraude' (a scam) con 'una decepción' (a disappointment) al usar el verbo defraudar.

Asegúrate de conjugar defraudar correctamente en el pasado: 'él defraudó', no 'él defraudo'.

To truly master defraudar, you must understand its relationship with other verbs of disappointment and deception. The most immediate synonym is decepcionar. In many cases, these two are interchangeable. However, decepcionar is more general and focuses on the feeling of sadness or dissatisfaction. Defraudar is more specific to the violation of trust or the failure to meet a high standard. If a cake doesn't taste good, it 'decepciona'. If a person you trusted with a secret tells everyone, they 'te han defraudado'. The choice between them often depends on the 'weight' of the expectation that was broken.

Defraudar vs. Decepcionar
Defraudar: Focuses on broken trust or failed promises. Often implies a moral failure.
Decepcionar: Focuses on the internal feeling of being let down or finding something unsatisfactory.

Aunque ambos significan 'disappoint', defraudar suena más serio que decepcionar en una relación personal.

Defraudar vs. Fallar
Defraudar: Specific to expectations and trust.
Fallar: A much broader verb meaning 'to fail', 'to malfunction', or 'to miss'. You can 'fallar un penalti' (miss a penalty) or 'fallar a un amigo' (fail a friend). 'Fallar' is more common in everyday, less formal speech.

Another interesting alternative is desilusionar. This verb specifically refers to the loss of 'ilusión' (hope, excitement, or a dream). If you were very excited about a trip and it gets canceled, you are 'desilusionado'. While 'defraudar' implies that someone else failed you, 'desilusionar' focuses on the death of your own hope. There is also frustrar, which is used when an external force prevents a plan or expectation from being fulfilled. A storm might 'frustrar' your plans for a picnic. In contrast, 'defraudar' usually requires a human or institutional agent who is responsible for the letdown.

Me desilusionó que no vinieras, pero me dolió más que me llegaras a defraudar con mentiras.

Defraudar vs. Engañar
Engañar: To trick, deceive, or lie to someone. This is an active process of making someone believe something false.
Defraudar: Can be a result of 'engañar', but it emphasizes the failure to meet the resulting expectation.

Finally, consider the verb traicionar (to betray). This is the strongest word in this family. While you can 'defraudar' someone by simply being mediocre, 'traicionar' implies a deliberate act of hostility or disloyalty. If a soldier gives secrets to the enemy, he 'traiciona' his country. If a politician fails to lower taxes as promised, he 'defrauda' his voters. Choosing the right word among these synonyms allows you to calibrate the exact level of intensity and the nature of the failure you are describing. 'Defraudar' sits comfortably in the middle: more serious than a simple disappointment, but often less malicious than a total betrayal.

Elegir entre decepcionar, defraudar o traicionar depende de la gravedad de la falta cometida.

No es lo mismo defraudar las expectativas de un jefe que traicionar la lealtad de un hermano.

How Formal Is It?

豆知識

The word originally had a strictly legal and financial meaning in Latin. The emotional sense of 'disappointing' developed later in the Romance languages as the concept of 'cheating' expectations was applied to personal relationships.

defraudar vs fraude

It's the noun form of 'defraudar'.

Fraude is the act of cheating (noun), while defraudar is the action (verb). In emotional contexts, we use 'decepción' as the noun.

Both involve disappointment.

Desilusionar is about losing hope or excitement. Defraudar is about someone failing to meet a promise or standard.

defraudar vs engañar

Both involve a lack of truth.

Engañar is the active act of lying. Defraudar is the result of that lie or the failure to meet an expectation.

Traicionar is much stronger and implies active disloyalty or hostility. Defraudar can be passive (just not being good enough).

よくある間違い
  • Using 'defraudar' only for money. Using it for both money and emotional disappointment.

    Many English speakers think it only means 'to commit fraud'. In Spanish, it's very common for 'to let someone down'.

  • Saying 'Defraudé mi amigo'. Saying 'Defraudé a mi amigo'.

    You must use the 'personal a' when the direct object is a person.

  • Conjugating as 'defruedo'. Conjugating as 'defraudo'.

    It is a regular verb. The stem 'defraud-' does not change.

  • Using 'un defraude' as a noun. Using 'un fraude' or 'una decepción'.

    'Defraude' is not a word in Spanish. Use 'fraude' for the act or 'decepción' for the feeling.

  • Thinking 'defraudado' only means 'cheated'. Knowing it also means 'disappointed'.

    If someone says 'Estoy defraudado', they usually mean they are sad because someone let them down.

ヒント

The Personal 'A'

Never forget the 'a' when 'defraudar' is followed by a person. 'Defraudar a María' is correct, while 'Defraudar María' is not. This is a very common mistake for beginners.

Intensity Matters

Use 'defraudar' when you want to show that trust was involved. If a stranger is rude to you, they 'decepcionan'. If your best friend is rude, they 'defraudan' your trust.

Hacienda is key

In Spain, the most common collocation for this word is 'defraudar a Hacienda'. If you hear this on the news, it always means tax fraud.

The 'AU' Sound

The 'au' in 'defraudar' is a diphthong. Try to pronounce it as one syllable, similar to the sound in 'caught' or 'cow', rather than 'a-u'.

Noun vs. Verb

Remember: 'defraudar' (verb) -> 'fraude' (financial noun) / 'decepción' (emotional noun). Don't say 'un defraude'—that word doesn't exist.

Expectations

The object of 'defraudar' is often 'las expectativas'. This is a very professional way to say something didn't live up to the hype.

Subjunctive Usage

After expressions of emotion like 'me duele que' or 'es triste que', always use the subjunctive: 'Me duele que me defraudes'.

Regional Use

While the meaning is consistent, in some Latin American countries, 'fallar' is more common for personal letdowns, while 'defraudar' stays in the legal/formal realm.

De-Fraud

Think of it as 'De-frauding' someone of the promise you made. You are taking away the 'truth' of your word.

Don't be too dramatic

If someone forgets to buy milk, don't say 'Me has defraudado'. It's too strong! Just say 'Se te olvidó la leche'.

暗記しよう

記憶術

Think of 'defraudar' as 'DE-FRAUD-ing' someone of their happiness or their money. When you defraud someone's expectations, you are taking away the joy they expected.

視覚的連想

チャレンジ

語源

From the Latin verb 'fraudare', which means to cheat, deceive, or deprive someone of something by trickery.

元の意味: To cheat or to deprive by fraud.

Romance (Latin)

文化的な背景

Be careful when accusing someone of 'defraudar'. In a professional setting, it can sound like a legal accusation of fraud even if you mean disappointment.

English speakers often misuse 'defraudar' by only using it for money, missing its powerful emotional use for disappointment.

Spanish news headlines often feature 'Famosos que defraudaron a Hacienda'. Literary works where characters face the moral dilemma of defrauding their heritage. Sports commentary during the 'Mundial' (World Cup) when big teams lose.

よくある質問

10 問

No, that's a common misconception for English speakers. In Spanish, it is very frequently used for emotional disappointment and broken trust in personal relationships. For example, 'No me defraudes' means 'Don't let me down'.

'Decepcionar' is more general and focuses on the feeling of being let down. 'Defraudar' is stronger and implies that there was a specific promise, trust, or high expectation that was violated. It carries more moral weight.

Yes, if the person being disappointed is a specific individual or group. For example: 'Defraudó a sus amigos'. If you are disappointing an abstract concept like 'expectations', you don't use the personal 'a': 'Defraudó las expectativas'.

Yes, if the movie was highly anticipated and failed to meet those high expectations. If it's just a random boring movie, 'me aburrió' or 'me decepcionó' is better. 'Me defraudó' implies you expected greatness.

Yes, it is a completely regular -ar verb. It follows the same conjugation pattern as 'amar' or 'hablar' in all tenses. This makes it easy to conjugate once you know the root 'defraud-'.

The common phrase is 'defraudar a Hacienda' or 'defraudar impuestos'. Hacienda is the Spanish tax agency. It literally means to cheat the tax office.

Yes, it is possible to use it reflexively. 'Me defraudé a mí mismo' means 'I let myself down' or 'I failed to meet my own standards'.

Yes, it is the past participle used as an adjective. You can say 'Estoy defraudado' to mean 'I am disappointed/let down'. Remember to change it to 'defraudada' for feminine subjects.

While 'fraude' is the noun for financial fraud, the noun for the emotional feeling is 'decepción'. You would say 'Fue una gran decepción' (It was a great disappointment).

It is neutral to formal. You can use it in a serious conversation with a friend, but it is also the standard term used in legal documents and news reports.
