At the A1 level, you should learn 'falhar' as a simple word for when things don't work. Think of it in terms of technology or simple actions. For example, if your phone is not working well, you can say 'O meu telemóvel está a falhar.' It is also useful for saying you cannot go to a meeting: 'Eu vou falhar o jantar.' At this stage, focus on the present tense (eu falho, tu falhas, ele falha) and the idea of 'missing' or 'not working.' Don't worry about complex nuances yet; just use it for basic mechanical issues or missing a simple event. It is a regular -AR verb, so it follows the same pattern as 'falar' (to speak) or 'trabalhar' (to work). Learning this early helps you describe the little problems of daily life in Portugal or Brazil.
At the A2 level, you begin to use 'falhar' in more varied contexts, such as letting someone down or missing a specific goal. You should learn the construction 'falhar com alguém' (to let someone down). For example, 'Não falhes comigo' (Don't let me down). You also start using it in the past tense (Pretérito Perfeito) to describe things that went wrong: 'O motor falhou ontem.' You should also understand that 'falhar' is used in sports for missing a goal or a pass. This level is about expanding from just 'technical failure' to 'human unreliability' in simple sentences. You are beginning to see the difference between 'falhar' and 'errar,' even if you still mix them up occasionally.
By B1, you should be comfortable using 'falhar' in the Imperfeito (past imperfect) to describe recurring issues: 'A internet falhava todas as noites.' You also start to use it in the conditional and subjunctive moods: 'Se o plano falhar, o que fazemos?' (If the plan fails, what do we do?). At this level, you understand that 'falhar' isn't used for failing school exams (you use 'reprovar' instead). you also start to use adverbs with it, like 'falhar redondamente' (to fail miserably). You can now describe more abstract concepts, like a strategy failing or a memory failing. Your usage is becoming more precise, and you understand the prepositional differences clearly.
At the B2 level, you can use 'falhar' to discuss more complex social and professional situations. You understand its use in the news, such as 'falha técnica' (technical failure) or 'falha humana' (human error/failure). You can use it metaphorically, such as 'falhar o alvo' (missing the mark) in a business strategy. You are also aware of the formal register, where 'falhar' might describe a lack of a certain quality, like 'falha-lhe a coragem' (he lacks courage). You can distinguish 'falhar' from 'fracassar' and 'avariar' with high accuracy. You use the verb in complex sentence structures, including the personal infinitive and all subjunctive tenses, to express doubt, possibility, or regret about failures.
At the C1 level, you have a nuanced command of 'falhar.' You use it in literary or highly formal contexts to describe existential or systemic failures. You understand the philosophical difference between 'o erro' (the mistake) and 'a falha' (the failure/flaw). You can discuss topics like 'a falibilidade humana' (human fallibility) using the noun form 'falha' and the verb 'falhar' interchangeably. You recognize idiomatic expressions and can use 'falhar' to describe subtle interruptions in patterns, like a heart rhythm or a structural weakness in an argument. Your vocabulary is rich enough to choose 'falhar' over 'fracassar' or 'derrotar' based on the exact degree of failure you wish to convey.
At the C2 level, 'falhar' is a tool for precise expression. You use it with total control in academic, legal, or technical discussions. You understand the etymological roots and how they influence its current usage compared to other Romance languages. You can use 'falhar' in highly idiomatic ways that even some native speakers might find sophisticated. You can write about 'falhas de mercado' (market failures) in economics or 'falhas geológicas' (geological faults) in science. You are sensitive to the rhythm of the language, using the verb to create specific rhetorical effects. Failure, for you, is not just a word but a spectrum of technical, social, and moral nuances that you navigate effortlessly.

falhar 30秒で

  • Falhar is a common Portuguese verb meaning 'to fail' or 'to malfunction' in technical, social, and physical contexts.
  • It is used for mechanical glitches, missing sports targets, letting people down, or failing to attend an event.
  • Do not confuse it with 'reprovar' (failing an exam) or 'errar' (making a factual or logical mistake).
  • It is a regular -AR verb, making it easy to conjugate in all tenses for all learners.

The Portuguese verb falhar is a versatile and essential term that every learner must master. At its core, it translates to 'to fail,' but its application spans mechanical malfunctions, social disappointments, and missed targets. Unlike the English word 'fail,' which can sometimes feel overly heavy or final, falhar often describes a specific instance where something did not perform as expected or a goal was not reached due to a technical or momentary lapse.

Mechanical Failure
This is perhaps the most common use in daily life. When your car engine won't start or your internet connection drops, the verb used is falhar. It implies a malfunction or a 'hiccup' in a system that usually works. For example, if a light bulb flickers, a Portuguese speaker might say it is starting to fail.

O motor do carro começou a falhar no meio da autoestrada.

Translation: The car engine started to fail in the middle of the highway.

Beyond the physical world, falhar enters the realm of human relationships. To 'falhar com alguém' means to let someone down or to break a promise. It suggests a lack of reliability. In a professional setting, if a project doesn't meet its deadline because of a team member's oversight, they have 'failed' in their duty. It is important to distinguish this from reprovar, which is specifically used for failing an exam or a school grade.

Missing a Target
In sports or hunting, falhar is used when you miss a shot or a goal. If a striker misses the net, the commentator will say he 'falhou o golo.' This physical sense of 'missing' is a key nuance that differentiates it from the abstract concept of failure.

Ele nunca costuma falhar um remate tão fácil.

Translation: He doesn't usually miss such an easy shot.

In a social context, the word can also mean 'to be absent.' If someone is missing from a meeting or a regular gathering, we might say they 'falharam.' This implies a break in a sequence or a routine. For instance, if you go to the gym every Monday but miss one week, you 'falhou' that session. This use emphasizes the interruption of a pattern rather than a moral failure.

The Nuance of Error
While 'errar' means to make a mistake (like 2+2=5), falhar means the attempt itself did not produce the result. If you try to jump over a puddle and land in the middle, you 'falhou' the jump. You didn't necessarily 'make a mistake' in logic; your execution simply failed to achieve the objective.

A nossa estratégia não pode falhar desta vez.

Translation: Our strategy cannot fail this time.

Finally, falhar is used in the context of death or 'passing away' in very specific, often older or literary contexts, though this is rare today. More commonly, you will hear it in the phrase 'falecer.' However, understanding the breadth of falhar—from a stuttering engine to a missed penalty kick—allows you to express a wide range of 'unsuccessful attempts' with the precision of a native speaker. It is a word about expectations versus reality.

Using falhar correctly requires understanding its prepositional partners and its various shades of meaning. In its simplest form, it is an intransitive verb, meaning it doesn't need an object. You can simply say 'O plano falhou' (The plan failed). However, when you want to specify what failed or who was affected, the structure changes slightly.

Falhar em + [Verb/Noun]
When you fail at something or fail to do something, you use the preposition 'em' (which often contracts to 'no', 'na', 'num', etc.). For example, 'Ele falhou em chegar a tempo' (He failed to arrive on time). This construction is very similar to the English 'fail in' or 'fail at'.

Muitos estudantes falham na organização do tempo.

Translation: Many students fail in time management.

When you let someone down, you use the preposition 'com'. This is a very common idiomatic use. 'Não falhes comigo' means 'Don't let me down' or 'Don't fail me.' It carries a weight of personal responsibility and trust. If you fail a friend, you 'falhou com um amigo.' This is distinct from 'errar com alguém,' which might mean you treated them badly by mistake.

Transitive Use: Missing Targets
In the context of sports, shooting, or even missing a specific appointment, falhar acts directly on the object. 'Eu falhei o alvo' (I missed the target). 'Ela falhou o autocarro' (She missed the bus - though 'perder' is more common for transport, 'falhar' can imply she was there but failed to catch it).

O avançado falhou o golo por poucos centímetros.

Translation: The striker missed the goal by a few centimeters.

In more complex sentences, falhar can be used to describe the absence of a quality. For example, 'Falha-lhe o juízo' (He lacks judgment/His judgment fails him). Here, the thing that is failing (judgment) is the subject, and the person it is failing is the indirect object (lhe). This is a more sophisticated way to use the verb, often found in literature or formal speech to describe a deficiency in someone's character or abilities.

The Imperfect and Future
Because falhar often describes a recurring mechanical issue, you will frequently hear it in the Imperfeito (Past Imperfect): 'O rádio falhava sempre que chovia' (The radio used to fail whenever it rained). In the future, it is often used as a promise: 'Não te falharei' (I will not fail you).

Se a luz falhar, temos velas no armário.

Translation: If the light fails (the power goes out), we have candles in the cupboard.

To sound like a native, pay attention to the intensity. To 'falhar redondamente' is to fail completely or 'miserably.' This adverbial pairing is very common when discussing businesses that went bankrupt or plans that were total disasters. By combining falhar with the right prepositions and adverbs, you can move from basic 'failure' to nuanced descriptions of life's many mishaps.

You will encounter falhar in a surprising variety of everyday situations in Portugal and Brazil. From the mechanic's garage to the football stadium, this word is a staple of the Lusophone experience. Understanding these contexts will help you recognize the word even when it's spoken quickly or colloquially.

In the News and Media
Journalists frequently use falhar to report on system failures. You might hear 'A rede elétrica falhou' (The power grid failed) or 'As negociações falharam' (The negotiations failed). In these contexts, the word carries a sense of formal reporting on a breakdown of order or process.

Os travões do camião falharam na descida da montanha.

Translation: The truck's brakes failed on the mountain descent.

In the world of sports, especially football (soccer), falhar is heard constantly. Commentators use it when a player misses a pass, a tackle, or a shot. 'Falhou o passe!' is a common cry when a ball goes out of bounds. It highlights the high stakes and the immediate consequence of a mistake in a fast-paced game. Fans will also use it to criticize their team: 'Eles falharam nos momentos decisivos' (They failed in the decisive moments).

Social and Professional Commitments
In your social life, if you can't make it to a dinner, you might say, 'Desculpa, mas vou ter de falhar hoje' (Sorry, but I'm going to have to miss/fail today). In an office, a manager might ask, 'Onde é que o processo falhou?' (Where did the process fail?) to identify a bottleneck or error in a workflow.

Não podemos falhar com o cliente nesta entrega.

Translation: We cannot fail the client on this delivery.

Technology is another major area. If your Wi-Fi is spotty, you'll say 'A internet está a falhar' (The internet is failing/cutting out). If an app crashes, you might say it 'falhou.' This technical usage is perhaps the most frequent for modern learners, as we rely so heavily on devices that inevitably falham from time to time.

Emotional and Personal Contexts
In more intimate settings, falhar can be quite heavy. A person might say 'Eu falhei como pai' (I failed as a father) or 'O meu coração falhou uma batida' (My heart skipped a beat). These uses show the verb's ability to move from the mundane (a missed bus) to the profound (personal identity and health).

A memória começa a falhar com a idade.

Translation: Memory begins to fail with age.

Whether it's a light that won't turn on or a friend who didn't show up, falhar is the word that captures that gap between what should have happened and what actually did. Listen for it in Portuguese soap operas (telenovelas) as well, where 'falhar' is often used in dramatic confrontations about broken trust and failed promises.

English speakers often trip up with falhar because the English word 'fail' has many synonyms in Portuguese that are context-dependent. Using falhar in every situation where you'd use 'fail' in English is a common mistake that can make your Portuguese sound unnatural or even confusing.

Mistake 1: Failing an Exam
In English, you 'fail a test.' In Portuguese, if you say 'Eu falhei no teste,' a native speaker might think you didn't show up for it or that the test paper itself was defective. To say you didn't pass, you must use reprovar or chumbar (very common in Portugal). Example: 'Eu reprovei no exame de condução' (I failed my driving test).

Não use falhar para notas escolares; use 'reprovar'.

Translation: Don't use 'falhar' for school grades; use 'reprovar'.

Another error is confusing falhar with errar. As mentioned before, errar is about making a mistake in logic or fact. If you spell a word wrong, you 'errou a palavra.' If you try to catch a ball and it slips through your fingers, you 'falhou a receção.' Using falhar when you mean 'to make a mistake' can sound like you're implying a system failure rather than a human error.

Mistake 2: Missing a Person
English uses 'miss' in many ways. You 'miss' a friend (sentir saudades), you 'miss' a bus (perder), and you 'miss' a target (falhar). Beginners often use falhar for all of these. If you say 'Falhei o meu amigo,' it sounds like you tried to hit him with something and missed, rather than that you miss his company!

Eu perdi o comboio (Not: Eu falhei o comboio).

Translation: I missed the train (standard usage).

Preposition errors are also frequent. Remember that 'falhar com' is for people you let down. If you say 'Eu falhei o meu pai,' it's grammatically okay but sounds like you missed hitting him. 'Eu falhei com o meu pai' means you let him down. That small word 'com' makes a massive difference in meaning.

Mistake 3: Overusing It for 'To Fail'
For big life failures—like a business going under or a marriage ending—natives often prefer fracassar. Falhar can feel a bit too small or technical for these major life events. 'A empresa fracassou' sounds more definitive and tragic than 'A empresa falhou,' which might just mean it failed to meet a specific monthly goal.

O seu casamento fracassou após um ano.

Translation: Their marriage failed (was a disaster) after a year.

By being aware of these distinctions—reprovar for grades, errar for mistakes, perder for transport, and fracassar for major life failures—you will use falhar exactly where it belongs: for the glitches, misses, and let-downs of everyday life.

To truly master falhar, you need to know its 'neighbors' in the Portuguese vocabulary. Several words overlap with it, and choosing the right one will elevate your fluency. Let's look at the most common alternatives and how they differ from falhar.

Fracassar vs. Falhar
Fracassar is the 'big brother' of falhar. It implies a total, often public, failure. A business fracassa when it closes down forever. A person fracassa in life. Falhar is more about a specific moment or a mechanical error. If your phone dies, it falhou; it didn't fracassou.

O projeto fracassou por falta de investimento.

Translation: The project failed (was a total bust) due to lack of investment.

Another important word is avariar. This is specifically for machines and electronics. While you can say 'O computador falhou,' it is much more common to say 'O computador avariou' if it's actually broken and needs repair. Falhar might just mean it's acting up temporarily, whereas avariar means it's out of commission.

Errar vs. Falhar
This is the most common confusion. Errar is to make a mistake (to be wrong). Falhar is to not succeed in an action. If you answer a question wrong, you errou. If you try to hand someone a glass and you drop it, you falhou in the hand-off. Errar is cognitive; falhar is often operational.

Eu errei a conta, mas não falhei o pagamento.

Translation: I made a mistake in the calculation, but I didn't fail the payment (miss the payment).

For missing appointments or transport, use perder. 'Perdi o autocarro' (I missed the bus). If you say 'falhei o autocarro,' it sounds like the bus was a target you were trying to hit. However, in a social sense, you can say 'Vou falhar o jantar' (I'm going to miss the dinner), which is a common way to say you won't be attending.

Desapontar vs. Falhar com
When it comes to feelings, desapontar means 'to disappoint.' While 'falhar com alguém' also results in disappointment, falhar com emphasizes the broken commitment, while desapontar focuses on the emotional state of the other person. 'Não me falhes' (Don't let me down - keep your word) vs. 'Não me desapontes' (Don't disappoint me - live up to my image of you).

Espero não desapontar os meus pais.

Translation: I hope not to disappoint my parents.

Lastly, consider faltar. This means 'to be missing' or 'to be absent.' If you don't go to class, you 'faltou à aula.' If you are missing a piece of a puzzle, 'falta uma peça.' Faltar is about absence; falhar is about an attempt that didn't work. Knowing these subtle differences will help you navigate Portuguese conversations with much more precision and confidence.

How Formal Is It?

The English word 'fail' and 'fallacy' come from the same Latin root 'fallere'. So when you 'falha' in Portuguese, you are etymologically 'deceiving' the expectation of success!

よくある間違い
  • Eu falhei o exame. Eu reprovei no exame.

    Use 'reprovar' for failing grades. 'Falhar' is for technical or situational failure.

  • Eu falho o meu amigo. Eu sinto saudades do meu amigo.

    'Falhar' never means to miss a person emotionally. Use 'sentir saudades'.

  • O computador está falhado. O computador está a falhar.

    Use the present continuous to describe a machine that is currently glitching.

  • Eu falhei o autocarro. Eu perdi o autocarro.

    Use 'perder' for missing public transport. 'Falhar' implies missing a target.

  • Eu falhei o meu pai. Eu falhei com o meu pai.

    Without 'com', it sounds like you missed hitting your father. With 'com', it means you let him down.

ヒント

Preposition Power

Always use 'com' for people ('falhar com o pai') and 'em' for tasks ('falhar em terminar'). This keeps your meaning clear.

Technical Glitches

If your Wi-Fi is acting up, say 'A internet está a falhar.' It's the most natural way to describe spotty service.

Declining Plans

Use 'Vou ter de falhar' to politely say you can't make it to a social gathering. It sounds better than just saying 'Não vou'.

Missing Shots

In football, use 'falhar o golo.' It describes the action of missing the net perfectly.

English Cognate

Connect 'falhar' with the English word 'fallible.' Humans are fallible (falíveis) and thus we fail (falhamos).

The LH Sound

Don't pronounce 'lh' as 'l'. It's like the 'lli' in 'billion'. Practice saying 'falha' slowly until the sound is distinct.

Formal Contexts

In business, use 'falha técnica' to describe errors. It sounds professional and precise.

Reliability

Remember that Portuguese culture values keeping your word. Saying someone 'falhou' is a serious statement about their character.

Certainty

The phrase 'Não falha!' is great for when you are 100% sure something will work, like a home remedy.

Regularity

Since it's a regular -AR verb, use it to practice your conjugation endings for all past and future tenses.

暗記しよう

記憶術

Think of a 'FAIL' that happens in a 'HALL' (falhar). You tried to run through the hall but you failed and fell.

視覚的連想

Imagine a car engine with a giant red 'X' over it, sputtering 'fa-lhar, fa-lhar' as it tries to start.

チャレンジ

Try to use 'falhar' in three different sentences today: one about a machine, one about a missed appointment, and one about a sports game.

語源

Derived from the Vulgar Latin *fallare, which comes from the Classical Latin 'fallere' meaning 'to deceive, trick, or lead into error.'

元の意味: The original sense was about deception or being tricked, which evolved into 'falling short' or 'failing to meet an expectation.'

It is a Romance verb, cognate with the Spanish 'fallar', French 'faillir', and Italian 'fallire'.

文化的な背景

Be careful when saying someone 'falhou' (failed) as a person; it is a very strong and potentially hurtful criticism.

English speakers often over-rely on 'falhar' for school grades, where 'reprovar' is mandatory. They also tend to use it for 'missing' people, which is incorrect.

The phrase 'Falha Nossa' (Our failure) is the Brazilian equivalent of 'Bloopers'. In sports commentary, 'Falhou o golo!' is an iconic exclamation. Technical reports on the 1755 Lisbon earthquake often discuss 'falhas geológicas' (fault lines).

'Falhar' is usually for specific, smaller, or technical failures (like a missed goal or a glitchy app). 'Fracassar' is for major life or business failures that are seen as total disasters.

You should say 'Eu perdi o autocarro'. If you say 'Eu falhei o autocarro', it sounds like you were trying to hit the bus with a stone and missed.

No. To miss a person emotionally, use 'sentir saudades de'. To miss seeing someone at an event, you could use 'não vi' or 'perdi'.

Yes, it is a perfectly regular -AR verb. This means it follows the same conjugation pattern as 'falar' or 'amar' in all tenses.

It means to let someone down or break a promise. It is a very common way to express that you weren't reliable for a friend or family member.
