What does funcionar mean?
Funcionar primarily means to work or to function. In everyday Brazilian Portuguese it can refer to mechanical operation, successful outcomes for plans or methods, or even how people act in specific roles. The core sense is being in operation or producing the intended result.
Core senses at a glance
Funcionar has three common senses:
1. Mechanical or electronic operation: a machine operates as intended.
2. Effectiveness of plans, methods, or ideas: something succeeds or produces the desired outcome.
3. Behavior or role: how a person functions in a job or social situation (less common, but used).
Basic conjugation patterns
Funcionar is a regular verb from the first conjugation (-ar). That means its conjugation follows a predictable pattern. Below are the simple present, past (pretérito perfeito), imperfect, and future forms for quick reference.
Present tense (presente do indicativo)
Eu funciono
Tu funcionas
Ele/ela/você funciona
Nós funcionamos
Vós funcionais
Eles/elas/vocês funcionam
Pretérito perfeito (simple past)
Eu funcionei
Tu funcionaste
Ele/ela/você funcionou

Eles/elas/vocês funcionaram
Imperfect past (pretérito imperfeito)

Using funcionar with machines and devices
The most literal and frequent use of funcionar is to say that something mechanical or electronic is working. In English, you might say the computer works or the phone is working. In Portuguese, funcionar covers this directly.
Typical sentence patterns
Subject + funcionar + (adverb or complement)
Example sentences:
O computador funciona bem.
O telefone não está funcionando.
A impressora funciona só com este cabo.
Notes:
Use não funciona or não está funcionando to express that something is broken. For temporary issues, the present progressive with estar + gerund can feel more natural: o carro não está funcionando hoje.
Using funcionar for plans, methods, and ideas
Funcionar is often used metaphorically to mean that a plan, arrangement, or method works or is effective. This use is extremely common in conversational Brazilian Portuguese.
Common structures
Algo funciona: indicating success of an idea or plan.
Alguma coisa funciona para alguém: saying something works for a person.
Example sentences:
O plano funcionou.
Aquela técnica não funcionou para mim.
Esse método funciona muito bem com estudantes iniciantes.
Notes:
When talking about plans, you often use the past tense pretérito perfeito to report success or failure: o plano funcionou or o plano não funcionou. To discuss general effectiveness, use the present: essa estratégia funciona.
Using funcionar for habits and roles
Less literally, funcionar can describe how people perform in roles or systems. For example, asking whether someone works well in a team or whether a system operates in practice.
Example sentences:
Ele funciona bem sob pressão. (He functions well under pressure.)
Esse time funciona melhor com um capitão experiente. (This team works better with an experienced captain.)
Notes:
In these contexts, funcionar emphasizes suitability or effectiveness rather than physical operation.
Negation and common modifiers
Negation with funcionar is straightforward. Place não before the verb to say something does not work or did not work.
Examples:
O elevador não funciona.
Essa ideia não funcionou como esperávamos.
Modifiers often used with funcionar include:
bem (well) — funciona bem
mal (poorly) — funciona mal
direito (properly) — não está funcionando direito
automaticamente — funciona automaticamente
Using funcionar in different tenses and moods
Because it is regular, you can confidently use funcionar in compound tenses and moods. The present perfect, conditional, and subjunctive cover common communicative needs.
Present continuous
Estar + gerund: estar funcionando
Example: O ar-condicionado está funcionando agora.
Conditional
Function as would work: funcionaria
Example: Esse sistema funcionaria melhor com mais memória.
Subjunctive uses
Present subjunctive is comum after que to express doubt, desire, or necessity: que funcione
Example: Espero que o projeto funcione.
Se funcionar, vamos continuar com o plano.
Common collocations and expressions
Knowing typical collocations can help you sound natural. Here are phrases frequently used with funcionar in Brazilian Portuguese.
funcionar bem / funcionar mal — to work well / to work poorly
funcionar direito — to work properly
funcionar automaticamente — to operate automatically
não funcionar — not to work
começar a funcionar — to start working
parar de funcionar — to stop working
Examples:
O aplicativo parou de funcionar depois da atualização.
Se o roteiro começar a funcionar, teremos sucesso.
Short dialogues to show natural use
Reading short dialogs can help you see how native speakers use funcionar in context.
Dialog 1:
— O micro-ondas funciona?
— Sim, funciona. Só não uso a função grill.
Dialog 2:
— A reunião funcionou como esperávamos?
— Funcionou, conseguimos fechar o contrato.
Dialog 3:
— Você acha que essa técnica vai funcionar com crianças?
— Acho que vai funcionar se usarmos brinquedos como recompensa.
Practical tips for learners
1. Memorize core conjugations: Because funcionar is regular, learning the -ar pattern helps you form many useful tenses.
2. Use context to choose the right tense: present for general truths, pretérito perfeito for completed actions, estar + gerund for ongoing problems.
3. Start with simple sentences about devices and then expand to plans and roles. Devices provide clear situations to practice the verb physically working or not.
4. Pay attention to collocations: combining funcionar with words like bem, direito, and parar de makes your speech more natural.
Cultural and usage notes
In Brazilian Portuguese, conversational tone and regional differences sometimes change which verbs are preferred. For machines and electronics, Brazilians commonly use funcionar but may also say dar problema or quebrar to indicate malfunction or breakage. In informal speech, você or ele often replaces subject pronouns when the context is clear. Also, using gerund forms like está funcionando is very natural in spoken Brazilian Portuguese to describe current status.
Examples with different registers
Formal: O novo software funcionará corretamente após a instalação.
Informal: O botão não está funcionando, acho que quebrou.
Neutral/conversational: Se isso funcionar, a gente consegue resolver rápido.
Troubleshooting common learner mistakes
1. Confusing funcionar with trabalhar: Use trabalhar for people with jobs or when someone works in a profession. Use funcionar for machines, plans, and roles functioning. Example: Ele trabalha como engenheiro vs A máquina funciona bem.
2. Incorrect tense: Beginners sometimes use present when they need past. If the event finished, use pretérito perfeito: O projeto funcionou ontem.
3. Missing auxiliary when describing ongoing action: Prefer está + gerund for something currently in operation or failing: A impressora está funcionando, not A impressora funciona now when you mean right now.
Related verbs and alternatives
Knowing synonyms helps vary your speech:
trabalhar — to work (people/jobs, sometimes machines informally)
rodar — to run, as software or engines (O programa não roda)
funcionar — to function, to work properly
operar — to operate, more formal (O equipamento opera normalmente)
Examples:
O software não roda no meu computador.
O equipamento opera em modo automático.
Conclusion
Funcionar is a valuable verb for talking about machines, plans, ideas, and roles in Brazilian Portuguese. It is regular and easy to conjugate, and it appears in many useful expressions and collocations. Practice the present, pretérito perfeito, and the gerund form to describe states and actions accurately: O telefone funciona, o plano funcionou, and o carro está funcionando. With these patterns you will be able to describe whether things work, whether plans succeed, and how people perform in different situations.
