Introduction
Knowing when to use ensinar a versus ensinar para is a common challenge for English-speaking learners of Brazilian Portuguese. Both look similar but convey different ideas about teaching: one focuses on teaching someone to do something, the other can emphasize teaching for a purpose or directing information toward someone. This article breaks down the grammar, gives clear rules, and shows natural examples used in Brazil.
Basic meaning and difference
Ensinar means to teach. The verbs and prepositions that follow change the focus of the sentence. With ensinar a you normally indicate the action someone learns—teaching someone to do something. With ensinar para you can indicate the recipient in contexts where you emphasize destination, purpose, or whom the teaching is intended for, but it is less common when introducing an infinitive.
Rule of thumb
Use ensinar a + infinitive to say teach someone to do a specific action. Use ensinar + direct object (person) and optionally para when you want to stress for whom or for what purpose something is taught. In many everyday contexts, Portuguese speakers simply say ensinar + personal direct object without any preposition.
Structure with ensinar a + infinitive
The most common structure to express teaching someone how to do something is ensinar a followed by an infinitive verb. The pattern is:
ensinar a + [infinitive verb] + (a) + pessoa
Note that the person being taught can appear before or after the verb, and sometimes the preposition a appears twice in casual speech (ainda que unnecessary). Native speakers frequently say the person first for emphasis: Eu ensinei meu irmão a dirigir.
Examples
Eu ensinei meu filho a nadar.
Ela ensinou o aluno a escrever melhor.
Nós ensinamos os voluntários a montar as barracas.
In these examples the focus is on the action learned: nadar, escrever, montar. The preposition a connects ensinar to the infinitive.
Pronouns and clitic placement
When you replace the person with a pronoun, placement follows standard clitic rules. In spoken Brazilian Portuguese, subject + verb + pronoun is common:
Eu ensinei-o a falar. (formal, less common)
Eu o ensinei a falar. (neutral, common)
Often you will find the person directly after ensinar without changing the meaning: Ele ensinou Maria a tocar violão.
Structure with ensinar para
Ensinar para is used when emphasizing the recipient or the target audience, or when the verb is not followed by an infinitive but by a noun phrase. It highlights to whom something is taught or for whom the teaching is intended. However, it is not the standard choice before an infinitive when the goal is to express learning an action.
When ensinar para is natural
Use ensinar para in contexts like teaching something intended for a group, teaching for a purpose, or when using nouns rather than an infinitive. Example contexts include classes, programs, or actions aimed at beneficiaries.
Examples
Ela ensina matemática para crianças do ensino fundamental.
O projeto ensina para comunidades rurais técnicas de agricultura sustentável.
Eles ensinam português para imigrantes.
Here the phrase emphasizes the audience: crianças, comunidades rurais, imigrantes. The content being taught is a noun phrase (matemática, técnicas de agricultura sustentável, português) rather than an infinitive action.
Alternative without para
In many cases you can drop para and simply say ensinar + direct object. Both forms are acceptable, but meaning and emphasis change slightly.
Ela ensina crianças matemática. (more direct, common in speech)
Ela ensina matemática para crianças. (emphasizes the audience)
When both forms appear with similar meaning
Some verbs and sentences allow both constructions with minimal difference. Context, emphasis, and regional preferences affect choice. In spoken Brazilian Portuguese you will often hear both forms. Compare these:
Eu ensinei João a cozinhar.
Eu ensinei a João a cozinhar. (more formal or written)
Both mean I taught João to cook. The second uses the indirect object introduced by a preposition before the verb. It is grammatically correct and common in more formal registers.
Placement of the indirect object
You can place the person as an indirect object before or after the verb. When using indirect object pronouns or names, speakers choose the order for emphasis or clarity:
Eu ensinei a minha irmã a costurar.
Eu ensinei para a minha irmã como costurar. (less natural with infinitive)
The version with para and an infinitive sounds clumsier and is not recommended for beginner learners trying to express teach someone to do something.
Verbs that behave differently
Some verbs related to ensinar, such as aprender, mostrar, ensinar-se, or instruir, influence preposition choice. For example, mostrar often uses para when indicating showing something to someone, while aprender pairs with a different pattern.
Examples with mostrar and instruir
Ela mostrou o documento para o chefe. (showed the document to the boss)
O instrutor instruiu os alunos sobre segurança. (instructed the students about safety)
Even though mostrar and instruir differ, the core idea is that the preposition usage depends on whether you indicate an action learned, the recipient, or additional complements.
Common mistakes and how to avoid them
Beginners often translate directly from English teach someone to do something and use ensinar para before an infinitive, which sounds unnatural. Avoid using ensinar para + infinitive when your goal is to show someone learned an action.
Incorrect versus correct
Incorrect: Eu ensinei para meu irmão a dirigir.
Correct: Eu ensinei meu irmão a dirigir.
Also acceptable: Eu ensinei a meu irmão a dirigir. (slightly formal)
Remember that ensinar a + infinitive is the standard pattern for teaching actions. Use ensinar para when emphasizing the audience or the intended beneficiaries, usually with noun phrases.
Cultural and usage notes
In Brazilian Portuguese everyday speech is flexible. People often omit prepositions or rearrange elements for rhythm and clarity. In classroom contexts, advertisements for courses, or NGO descriptions, you will frequently see both forms, but each maintains its nuance.
In informal conversation, speakers prefer short, natural constructions: Eu ensinei ela a ler or Eu ensinei minha irmã a cozinhar. Formal writing may use a + pronoun or place the indirect object before the verb: Ensinei a ela a usar o computador.
When learning, focus first on mastering the basic and most common pattern: ensinar a + infinitive. Once comfortable, pay attention to native speech and written texts to notice how ensinar para is used with audiences and noun complements.
More natural example scenarios
1) Family context
Minha mãe me ensinou a fazer arroz. (Focus on the action learned)
2) Classroom or course description
O curso ensina técnicas de edição de vídeo para iniciantes. (Focus on audience and content)
3) Volunteer program
Eles ensinam finanças pessoais para jovens de comunidades. (Emphasizes beneficiaries)
4) Teaching a skill directly
Eu ensinei Pedro a consertar a bicicleta. (Direct teaching of an action)
Summary of rules
Use these simple guidelines to choose between ensinar a and ensinar para:
– Ensinar a + infinitive = teach someone to do something (most common for actions).
– Ensinar para + noun phrase = teach something intended for or aimed at a certain audience (emphasis on recipient or purpose).
– Ensinar + person + noun = often used in speech without any preposition to stress the taught person.
– When in doubt and you mean teach someone how to do an action, use ensinar a + infinitive.
Conclusion
Mastering the difference between ensinar a and ensinar para will make your Portuguese sound more natural and precise. Remember that ensinar a + infinitive expresses teaching someone to do an action, while ensinar para highlights the audience or purpose and is common with noun phrases. Listen to Brazilian speakers and read examples to internalize the patterns. With practice, choosing the right form will become instinctive.
