Basic meanings: helping to do vs helping with
Start with the simplest distinction. Use ajudar a when the verb that follows indicates an action someone helps another person to perform. Use ajudar com when referring to assistance involving a noun, object, task, or tool.
Think of ajudar a as helping someone to do something and ajudar com as helping someone with something. This division aligns with many English patterns, but in Portuguese the preposition choice affects sentence structure and verb forms.
Grammar rule for ajudar a
When you use ajudar a, it is usually followed by an infinitive verb. The structure is
ajudar a + infinitivo
Compare to English patterns like help to do or help do. In Brazilian Portuguese the preposition a is standard and links the helper to the action being assisted.
Examples of ajudar a
Eu vou ajudar a preparar o jantar.
Ela pode ajudar a organizar o evento.
Ele ajudou a consertar o computador.
Notice that the verb after ajudar a stays in the infinitive: preparar, organizar, consertar. This indicates the action the helper helps to perform.
Grammar rule for ajudar com
Use ajudar com when the complement is a noun or a gerund phrase that behaves like a noun, or when you want to emphasize the instrument, material, or specific matter of help. The structure is
ajudar com + substantivo / gerúndio
This construction focuses on what the help involves, rather than the exact action being assisted.
Examples of ajudar com
Você pode ajudar com a limpeza da casa?
Ela me ajudou com o relatório.
Eles vão ajudar com os preparativos.
Here, ajuda refers to the task, object, or part of a process: the cleaning, the report, the preparations. The phrase after ajudar com is typically a noun phrase.
When both appear possible: nuances and preference
Some contexts allow both ajudar a and ajudar com, but the nuance changes. Choosing one or the other highlights a different perspective on the help.
Same idea, different focus
Compare these sentences:
Ele ajudou a pintar a sala.
Ele ajudou com a pintura da sala.
The first emphasizes the action of painting. The second emphasizes the item or job being helped with, the painting itself. Both are correct, but the first paints a picture of participating in the act; the second suggests assisting in the task as a part or resource.
When only one is natural
Some verbs and expressions pair naturally with one preposition. For verbs of motion or change of state combined with help to perform the action, ajudar a is usually required. For help concerning an object, document, or tool, ajudar com fits better.
Incorrect: Ela ajudou com organizar a festa.
Correct: Ela ajudou a organizar a festa.
Incorrect: Eu vou ajudar a o relatório.
Correct: Eu vou ajudar com o relatório.
Pronouns and placement
When you use direct and indirect object pronouns with ajudar, placement rules follow normal Portuguese pronoun order. In Brazilian Portuguese, object pronouns typically come before the verb in spoken and less formal writing (me, te, nos, etc.).
Examples with pronouns
Eu vou te ajudar a estudar para a prova.
Ela me ajudou com o computador.
Nós vamos ajudá-lo a resolver o problema. (formal WRITTEN form: vamos ajudá-lo)
Note that when attaching infinitives and pronouns in formal written forms, European Portuguese often uses enclisis (ajudar-lhe), but in Brazilian Portuguese proclisis is more common in spoken and informal written contexts (me ajudou, te ajudarei).
Tense and aspect with ajudar a
Because ajudar a is followed by an infinitive to express the action being helped, tense and mood on the main verb determine timing. The infinitive itself remains non-finite, so time relations come from the conjugated aider verb.
Examples across tenses
Presente: Nós ajudamos a montar a mesa agora.
Pretérito: Ela ajudou a terminar o trabalho ontem.
Futuro: Eles vão ajudar a instalar o novo software amanhã.
Subjuntivo: Espero que ele ajude a resolver a situação.
Keep in mind that when the subjunctive or conditional mood is necessary, it applies to the main clause; the infinitive after ajudar a still indicates the action aided.
Using gerunds and progressive ideas
Sometimes you will see gerunds used after ajudar com to describe ongoing assistance. While ajudar a normally pairs with infinitives, ajudar com can combine smoothly with gerunds when describing the kind of help provided.
Examples
Ela está ajudando com preparando os convites. (less common; better: Ela está ajudando com a preparação dos convites.)
Eles estavam ajudando com organizando a mudança. (less natural; better to rephrase with substantivo)
In practice, native speakers prefer a noun phrase after ajudar com rather than the gerund directly. For clarity, use a noun like preparação, organização, ou montagem.
Common collocations and everyday usage
Here are common pairings you’ll hear often in Brazil. Memorizing typical collocations helps you sound natural.
ajudar a + verb: ajudar a estudar, ajudar a entender, ajudar a cozinhar, ajudar a encontrar.
ajudar com + noun: ajudar com as compras, ajudar com o transporte, ajudar com a lição, ajudar com a bagagem.
Politeness and requests
When asking for help, Brazilians often use polite constructions. You can use ajudar a or ajudar com depending on the focus.
Você pode me ajudar a entender isso?
Você pode me ajudar com isso?
The first asks for help to grasp or do something; the second asks for assistance with a specific thing or task. Both are polite and widely used.
Regional and style notes
Brazilian Portuguese is flexible, and spoken language often simplifies structures. In casual speech, learners may hear variants like ajudar em or simply ajudar followed by a noun, especially in some regions. However, for clear and standard usage, prefer ajudar a before infinitives and ajudar com before nouns.
Formal vs informal contexts
In formal writing or careful speech, maintain the standard preposition patterns. In informal conversation, Brazilians might omit the preposition or mix forms, but learners should learn the correct patterns first and then adapt to colloquial variations as they become more comfortable with the language.
Common learner mistakes and how to avoid them
Many learners translate directly from English and choose the wrong preposition. Avoid these pitfalls:
1. Translating help to do as ajudar com + noun. Example mistake: Eu vou ajudar com limpar a casa. Correction: Eu vou ajudar a limpar a casa.
2. Using ajudar a with a noun immediately after. Example mistake: Ela ajudou a o relatório. Correction: Ela ajudou com o relatório.
3. Forgetting to use the infinitive after ajudar a. Example mistake: Eles ajudam a que eu faça. Correction: Eles ajudam a eu fazer or, more natural, Eles ajudam-me a fazer.
To avoid errors, decide whether you want to highlight the action (use ajudar a) or the thing/task (use ajudar com), and structure your sentence accordingly.
Quick decision guide
When trying to decide quickly:
– If the next word is a verb in English (to + verb), use ajudar a + infinitive.
– If the next word is a noun (the report, the bags, the cleaning), use ajudar com + noun.
Examples for the quick guide
I will help to cook = Eu vou ajudar a cozinhar.
I will help with the cooking = Eu vou ajudar com a comida / com o cozimento / com a preparação.
She helped to find the keys = Ela ajudou a encontrar as chaves.
She helped with the keys = Ela ajudou com as chaves. (less common; context needed)
Subtle differences in meaning
Sometimes the choice between ajudar a and ajudar com changes the implied level of involvement. Ajudar a often implies active participation in the action; ajudar com can suggest support, provision of materials, or partial contribution.
Example: Ele ajudou a montar o móvel suggests he actively participated in building it.
Ele ajudou com o móvel could mean he helped move it, brought tools, or assisted in some supporting way.
Real-life conversational examples with translations

Ele ajudou com os convites e também trouxe o bolo. (He helped with the invitations and also brought the cake.)
Conclusion
Mastering the difference between ajudar a and ajudar com makes your Portuguese sound more natural and precise. Use ajudar a when assisting with an action expressed by an infinitive, and use ajudar com when referring to a noun, object, or specific task. Pay attention to context, pronoun placement, and register, and you will quickly internalize the patterns used in everyday Brazilian Portuguese.
