At the A1 level, you should focus on the most basic use of 'acostumado' to describe simple daily habits. Think of it as the Portuguese equivalent of 'used to'. At this stage, the most important thing is to remember that the word changes its ending: 'acostumado' for men and 'acostumada' for women. You will mostly use it with the verb 'estar' (to be). For example, if you are learning to live in a new place, you might say 'Estou acostumado com o calor' (I am used to the heat). Don't worry too much about complex grammar yet; just focus on the 'estar + acostumado/a + com + noun' pattern. This will help you express your comfort level with food, weather, and basic routines. It is a very helpful word for beginners because it allows you to explain why you might find something strange or why you are already comfortable with it. Remember: 'acostumado' is for things you have done many times before.
At the A2 level, you can start expanding your use of 'acostumado' by incorporating verbs. Instead of just being used to 'things' (nouns), you can talk about being used to 'doing things'. This requires the preposition 'a'. For example: 'Estou acostumado a estudar à noite' (I am used to studying at night). You should also practice the plural forms: 'Nós estamos acostumados' (We are used to). At this level, you should also be able to use the negative form to express culture shock or new experiences: 'Eu não estou acostumada a comer feijão no café da manhã' (I am not used to eating beans for breakfast). You are also starting to see the difference between 'estar acostumado' (a state) and 'acostumar-se' (the process of getting used to something). Try to use 'acostumado' to describe your routine and how it has changed since you started learning Portuguese.
As a B1 learner, you should have a firm grasp of the 'estar acostumado a/com' structure and start using it in more varied contexts. You can now use it to describe psychological states and social situations. For instance, you might discuss being 'acostumado com o ritmo de vida' (used to the pace of life) or 'acostumado a lidar com pessoas' (used to dealing with people). You should also be aware of the synonym 'habituado', which you might encounter in more formal texts or when speaking with people from Portugal. This is the level where you should also learn the common phrase 'mal acostumado', which means 'spoiled' or 'pampered'. You can use this to talk about children, pets, or even yourself in a humorous way. Your sentences should become more complex, using 'acostumado' in subordinate clauses, such as 'Como eu já estava acostumado com o sistema, não tive dificuldades' (Since I was already used to the system, I didn't have difficulties).
At the B2 level, you should be able to use 'acostumado' with nuance and precision. You can distinguish between being 'acostumado' (habitual) and being 'adaptado' (well-integrated) or 'familiarizado' (knowledgeable). You should also be comfortable using the word in different tenses, such as the imperfect ('Eu estava acostumado') or the future ('Eu vou ficar acostumado'). This level requires you to understand how 'acostumado' fits into more professional or academic discussions. For example, you might read about how a population is 'acostumada a crises econômicas'. You should also be able to use the reflexive verb 'acostumar-se' fluently in all its forms to describe the process of adaptation. Your ability to use 'acostumado' should now feel natural, and you should be able to catch yourself if you accidentally use 'ser' instead of 'estar'. You can also start using more advanced collocations like 'estar mal acostumado a ter tudo na mão'.
At the C1 level, you are expected to use 'acostumado' and its synonyms like a native speaker. This includes understanding the subtle stylistic differences between 'acostumado', 'habituado', and 'familiarizado'. You can use 'acostumado' to express complex social commentaries or philosophical ideas about human nature and habit. You should be able to use it in highly formal writing, perhaps opting for 'habituado' to maintain a certain register, or using 'acostumado' in a speech to sound more relatable. You will also understand idiomatic expressions and metaphors involving the concept of habituation, such as 'estar calejado'. At this level, you should be able to discuss the etymology of the word (from 'costume') and how it relates to the cultural identity of Lusophone countries. Your usage should be flawless, including the correct application of the 'crase' (e.g., 'acostumado à rotina') and complex sentence structures involving multiple clauses.
At the C2 level, your mastery of 'acostumado' is complete. You can play with the word, using it in irony, sarcasm, or deep poetic contexts. You understand the historical evolution of the word and its regional variations across the entire Lusophone world, from Angola to Macau. You can analyze literature where the theme of being 'acostumado' is central to a character's development or a story's atmosphere. You can use the word to discuss high-level concepts in sociology, psychology, and history. For you, 'acostumado' is not just a vocabulary word but a tool for precise expression. You can effortlessly switch between 'acostumado', 'habituado', 'adaptado', 'familiarizado', and 'condicionado' depending on the exact shade of meaning you wish to convey. You are also capable of identifying and explaining the subtle differences in how 'acostumado' is used in a legal document versus a popular song lyric.

acostumado in 30 Seconds

  • Acostumado is a Portuguese adjective meaning 'used to' or 'accustomed'. It describes a state of familiarity gained through repetition or time.
  • It must agree in gender (acostumado/acostumada) and number (acostumados/acostumadas) with the subject it describes in the sentence.
  • It is primarily used with the verb 'estar' and followed by the prepositions 'a' (for verbs) or 'com' (for nouns).
  • Commonly heard in daily life, it can also mean 'spoiled' when used in the phrase 'mal acostumado', referring to someone pampered.

The word acostumado is a fundamental pillar of the Portuguese language, serving as both a past participle of the verb acostumar and a versatile adjective. At its core, it describes the state of being habituated, used to, or familiarized with a specific condition, environment, or behavior. When you say you are acostumado, you are communicating that the 'newness' or 'strangeness' of a situation has worn off through repetition. This word is essential for expressing adaptation, whether you are talking about the climate of a new city, the rigors of a new job, or the peculiar quirks of a new friend. It implies a process of transition from a state of effort or surprise to a state of normalcy and ease. In Portuguese culture, which values social integration and resilience, being acostumado often carries a connotation of endurance and local knowledge.

Grammatical Gender
The word changes based on the subject: 'acostumado' for masculine and 'acostumada' for feminine. Plurals are 'acostumados' and 'acostumadas'.

Depois de morar cinco anos na Sibéria, ele já está acostumado com o frio extremo.

Beyond physical adaptation, the word is used in psychological contexts. It can describe a person who has become desensitized to something, for better or worse. For instance, one might be acostumado to a high-stress environment, meaning they no longer feel the physiological panic that a newcomer might experience. It is frequently paired with the verb estar (to be) because it describes a temporary or resulting state, rather than an inherent, permanent quality (which would use ser). However, in some contexts, if habituation is seen as a defining character trait, ser might appear, though it is much less common. Understanding this word is key to discussing your personal history and your level of comfort in various Portuguese-speaking settings, from the bustling streets of São Paulo to the quiet villages of the Alentejo.

Common Prepositions
It is almost always followed by 'a' or 'com'. 'Acostumado a' is usually followed by a verb, while 'acostumado com' is followed by a noun.

Nós não estamos acostumados a comer tão tarde da noite.

In everyday conversation, you will hear this word when people discuss their routines. It is the bridge between the 'extraordinary' and the 'ordinary'. When a Brazilian moves to Portugal, they might say they are not acostumados to the different vocabulary or the colder winters. Conversely, a tourist might find the noise of a local market overwhelming, while the vendor is perfectly acostumado to the chaos. This word encapsulates the human ability to adapt and normalize even the most challenging circumstances. It is a word of resilience and familiarity.

Ela está acostumada com o barulho do trânsito em frente à sua casa.

Nuance of 'Mal Acostumado'
This phrase means 'spoiled'. It refers to someone who has become accustomed to having things their way or receiving too much attention.

Aquele cachorro é muito mal acostumado; ele só dorme no sofá.

Você já se sente acostumado com a nova rotina de trabalho?

Using acostumado correctly requires attention to two main things: subject-adjective agreement and the choice of preposition. Because it functions as an adjective in most contexts, it must mirror the gender and number of the person or thing it describes. If you are a man, you say estou acostumado. If you are a woman, estou acostumada. If you are speaking for a group of women, estamos acostumadas. This is a common pitfall for English speakers who are used to the gender-neutral 'accustomed'.

The Preposition 'A'
Use 'a' when the following word is a verb (in the infinitive). This indicates a habit of doing something.

Eu estou acostumado a acordar às seis da manhã todos os dias.

When you are describing a familiarity with a thing, a person, or a noun, the preposition com is the standard choice. This is equivalent to 'used to [noun]' in English. For example, if you move to a city with a lot of hills, you would say you are acostumado com as ladeiras. It is important to note that com will often contract with articles: com + o = com o, com + a = com a, com + os = com os, and com + as = com as.

The Preposition 'Com'
Use 'com' when the following word is a noun or a pronoun. This indicates familiarity with an object or situation.

Eles já estão acostumados com o sotaque regional daqui.

Another interesting usage is the negative form. To say you are not used to something, you simply add não before the verb estar. This is very common when travelers are experiencing culture shock. 'Não estou acostumado com isso' (I'm not used to this) is a phrase you might hear frequently. Furthermore, you can use intensifiers like muito (very) or completamente (completely) to add depth to your statement.

Reflexive Verb Usage
The process of getting used to something uses the reflexive verb 'acostumar-se'. Example: 'Eu me acostumei com o clima'.

Você vai ficar acostumado rapidinho com as novas regras da empresa.

Finally, consider the placement of acostumado in questions. It usually follows the verb estar and the subject. 'Você está acostumado?' is the standard way to ask 'Are you used to it?'. In Brazil, the subject 'você' is often dropped if it's clear from the context, leaving just 'Está acostumado?'. In Portugal, you might hear 'Estás habituado?' more often, but 'acostumado' is perfectly understood and used there as well.

Nós ainda não estamos acostumados a lidar com tanta pressão.

Ela sempre foi acostumada a ter o melhor da vida.

The word acostumado is ubiquitous in the Lusophone world. You will hear it in the most mundane settings, such as a bakery (padaria) where a regular customer is acostumado to getting their bread at a certain time, to the highest levels of political discourse where a leader might say the people are acostumados to certain social policies. It is a word that bridges the gap between the personal and the collective experience.

In the Workplace
Colleagues use it to describe workflow. 'O chefe está acostumado com relatórios curtos' (The boss is used to short reports).

Não se preocupe, eu já estou acostumado a trabalhar sob pressão.

In Brazilian music, particularly in Samba and MPB (Música Popular Brasileira), acostumado often appears in lyrics about heartbreak or the grind of daily life. It might describe someone who is 'used to suffering' (acostumado a sofrer) or 'used to the solitude' (acostumado com a solidão). This poetic usage highlights the word's ability to convey a sense of weary resignation or stoic acceptance. When you listen to songs by Cartola or Adoniran Barbosa, listen for this word as they describe the lives of ordinary people in Rio or São Paulo.

In Family Life
Parents often use it regarding their children's habits. 'Ele está acostumado a dormir com a luz acesa'.

As crianças estão acostumadas com a comida da avó.

In the news, you might hear acostumado when journalists discuss public reactions to economic changes. For example, 'O consumidor brasileiro está acostumado com a inflação' (The Brazilian consumer is used to inflation). Here, it takes on a more sociological tone, describing a collective adaptation to long-term national challenges. Whether it's a casual chat over coffee or a formal news broadcast, acostumado is the go-to word for describing the human state of being 'settled in' to a reality.

Você já está acostumado com o ritmo frenético desta cidade?

Eu não estou acostumado a ser tratado com tanta grosseria.

Travel and Tourism
Tour guides often ask: 'Vocês estão acostumados a caminhar longas distâncias?' (Are you used to walking long distances?).

One of the most frequent errors made by English speakers is using the wrong auxiliary verb. In English, we say 'I **am** used to'. In Portuguese, learners often translate this literally as 'Eu **sou** acostumado'. While grammatically possible in very specific philosophical contexts, it sounds unnatural in 99% of daily situations. The correct verb is estar because being accustomed is viewed as a state you have entered, not an essential part of your being. Using ser makes it sound like 'being accustomed' is your permanent personality trait, which is confusing.

The 'Ser' vs 'Estar' Trap
Wrong: 'Eu sou acostumado com o frio.' Correct: 'Eu estou acostumado com o frio.'

Ele está acostumado (Correct) vs. Ele é acostumado (Incorrect in most contexts).

Another common mistake involves the prepositional choice. Many learners forget the preposition entirely, saying 'Estou acostumado o frio' instead of 'Estou acostumado **com** o frio'. Others might use the English-influenced 'em' (in) or 'para' (for), which are incorrect. Remember: acostumado needs a bridge to its object. If it's an action, use a. If it's a thing, use com. Mixing these up—like saying 'acostumado com acordar'—is a hallmark of a beginner level, though it's usually understood.

Gender Agreement Neglect
Male speaker: 'Estou acostumado.' Female speaker: 'Estou acostumada.' Groups: 'Estamos acostumados/as.'

Maria está acostumada (Correct) vs. Maria está acostumado (Incorrect).

Lastly, don't confuse acostumado with the verb costumar. While they share a root, they are used differently. Costumar is used to say 'I usually do something' (Eu costumo acordar cedo), whereas estar acostumado means 'I am used to doing something' (Eu estou acostumado a acordar cedo). The former describes the frequency of an action, while the latter describes the subject's internal state of familiarity. Using acostumado to mean 'usually' without the verb estar is a major grammatical error.

Eu costumo viajar no verão (I usually travel) vs. Eu estou acostumado a viajar (I am used to traveling).

Nós não estamos acostumados a este tipo de comportamento.

The 'A' vs 'À' Confusion
If the noun following 'acostumado a' is feminine and has an article, you must use the crase: 'Acostumado à rotina'.

While acostumado is the most common way to express being 'used to' something, Portuguese offers several alternatives that can add precision or formality to your speech. The most direct synonym is habituado. This word is slightly more formal and is very common in European Portuguese. In Brazil, it sounds a bit more sophisticated or clinical. If you want to sound like a native in Lisbon, 'estou habituado' is your best bet; in Rio, 'tô acostumado' is the way to go.

Habituado vs Acostumado
Habituado: More formal, common in Portugal. Acostumado: More common in Brazil, used in all registers.

O paciente já está habituado com a medicação diária.

Another alternative is familiarizado. This word specifically implies knowledge and understanding rather than just a physical or repetitive habit. If you are familiarizado with a software, it means you know how it works. If you are acostumado with it, it might just mean you use it every day without necessarily being an expert. Then there is adaptado, which emphasizes the successful result of a change. You might be acostumado to a new city (you know the streets), but are you adaptado (do you feel at home there)?

Familiarizado vs Adaptado
Familiarizado: Focuses on knowledge/information. Adaptado: Focuses on comfort/integration after a change.

Ainda não estou totalmente familiarizado com os novos termos técnicos.

For a more colloquial or even slang-heavy approach, Brazilians might use the expression estar em casa (to be at home) to mean they are very used to a situation. If someone is very experienced in a certain field, you might say they are a macaco velho (old monkey), implying they are so acostumados to the tricks of the trade that they can't be fooled. In contrast, calejado (calloused) is used when someone is used to something difficult or painful, suggesting they have developed a 'thick skin'.

Ele já está calejado de tanto levar rasteira da vida.

Depois de meses, finalmente me sinto adaptado ao novo país.

Practical Summary
Use 'acostumado' for 90% of cases. Use 'habituado' for formal writing. Use 'calejado' for tough experiences. Use 'familiarizado' for learning processes.

Adaptado implies you have successfully changed to fit a new environment; acostumado just means it's no longer strange.

Estou acostumado com o frio, mas não estou adaptado a viver aqui.

acostumado vs familiarizado

Both mean 'knowing' something well.

Familiarizado is about knowledge/info; acostumado is about habit/repetition.

Estou familiarizado com o manual, mas não estou acostumado a usar a máquina.

acostumado vs condicionado

Both involve behavioral patterns.

Condicionado is psychological/scientific (like Pavlov's dogs); acostumado is everyday language.

O rato está condicionado ao som. Eu estou acostumado ao som.

acostumado vs afeito

Both mean 'used to'.

Afeito is literary and often implies a natural inclination or long-term bond.

Ele é um homem afeito às lides do campo.

How to Use It

frequency

Very high in both spoken and written Portuguese.

Common Mistakes
  • Eu sou acostumado com o frio. Eu estou acostumado com o frio.

    You must use 'estar' for states resulting from a process. 'Ser' is for permanent characteristics.

  • Ela está acostumado a ler. Ela está acostumada a ler.

    The adjective must agree with the feminine subject 'Ela'.

  • Estou acostumado de acordar cedo. Estou acostumado a acordar cedo.

    The correct preposition before a verb is 'a', not 'de'.

  • Nós estamos acostumado com isso. Nós estamos acostumados com isso.

    The adjective must be plural to match 'Nós'.

  • Estou acostumado o barulho. Estou acostumado com o barulho.

    You cannot omit the preposition 'com' before a noun.

Tips

Gender Agreement

Always match the ending to the subject. If you are a woman, never say 'acostumado'. It's a very common mistake for English speakers.

Use 'Estar'

Stick with the verb 'estar'. Using 'ser' is one of the quickest ways to sound like a non-native speaker.

Preposition Choice

Remember: 'A' for Actions (verbs), 'Com' for Concepts/Things (nouns). This simple rule will solve 90% of your preposition doubts.

Mal Acostumado

Use this phrase carefully. It's great for teasing friends or talking about pets, but can be offensive if used seriously with a stranger.

Informal Contraction

In Brazil, say 'Tô acostumado' to sound more natural and relaxed in conversation.

Formal Synonym

If you are writing a formal letter or academic paper, try using 'habituado' or 'familiarizado' for a more sophisticated tone.

Regional Sounds

In Rio de Janeiro or Portugal, the 's' in 'acostumado' sounds like 'sh'. In São Paulo or the South of Brazil, it sounds like a normal 's'.

The 'Custom' Link

Link 'acostumado' to 'custom'. A custom is something you do repeatedly until you are 'acostumado'.

The Crase

If you use 'acostumado a' followed by a feminine noun with an article, don't forget the crase: 'acostumado à vida'.

Reflexive Process

If you want to talk about the *process* of getting used to something, use 'acostumar-se'. 'Acostumado' is only for the *result*.

Memorize It

Mnemonic

Think of 'A CUSTOM'. If you follow 'A CUSTOM' many times, you become 'ACOSTUMADO'.

Visual Association

Imagine a person sitting comfortably in a very old, worn-out armchair that has perfectly molded to their body shape.

Challenge

Try to use 'acostumado' in three different sentences today: one about the weather, one about your food habits, and one about your work or study routine.

Word Origin

Derived from the Latin 'consuetudinem', which means 'custom' or 'habit'. It passed through Vulgar Latin 'costuma' before reaching Portuguese.

Original meaning: The original sense was related to social customs and collective traditions rather than individual habits.

Romance (Latin origin).

Cultural Context

Be careful when calling someone 'mal acostumado' (spoiled); it can be seen as an insult depending on the tone and relationship.

English speakers often confuse 'I am used to' (state) with 'I used to' (past action). In Portuguese, 'acostumado' only covers the 'state' part. For 'I used to', you use the imperfect tense.

The song 'Mal Acostumado' by Araketu (a massive hit in Brazil). Literary works by Machado de Assis often explore characters who are 'acostumados' to social hypocrisy. The phrase 'O homem é um animal de costumes' (Man is a creature of habit) is a common philosophical citation.

Frequently Asked Questions

10 questions

It is better to say 'Eu estou acostumado'. In Portuguese, being used to something is considered a state resulting from a process, which requires the verb 'estar'. 'Ser' would imply it is a permanent, essential part of your identity, which sounds strange to native speakers.

Generally, use 'acostumado a' before a verb (e.g., acostumado a correr) and 'acostumado com' before a noun (e.g., acostumado com o trânsito). In formal writing, 'acostumado a' can be used for both, but 'com' is very common for nouns in speech.

You use the reflexive verb 'acostumar-se' in the present continuous: 'Estou me acostumando' (Brazil) or 'Estou-me a acostumar' (Portugal).

Yes, it is perfectly understood and used in Portugal, although 'habituado' is slightly more frequent in European Portuguese than it is in Brazilian Portuguese.

It means 'spoiled' or 'pampered'. It describes someone who is used to getting everything they want or having things easy. It can be used for children, pets, or adults.

Yes! This is very important. A man says 'acostumado', a woman says 'acostumada', a group of men (or mixed) says 'acostumados', and a group of women says 'acostumadas'.

Yes. 'O cachorro está acostumado com a ração' (The dog is used to the kibble).

They are almost identical in meaning. 'Habituado' is more formal and more common in Portugal. 'Acostumado' is the standard, everyday word in Brazil.

You say 'Não estou acostumado com isso' or 'Não estou acostumada com isso'.

No, it is primarily an adjective or a past participle. The noun form is 'costume' or 'hábito'.
