The Personal Infinitive: Verbs with People Attached

Use the Personal Infinitive to clarify exactly *who* is doing the action in an infinitive phrase.

Grammar Rule in 30 Seconds

The Personal Infinitive allows you to specify who is performing an action within an infinitive phrase.

  • Use it when the subject of the infinitive differs from the main clause subject: 'Para eles lerem'.
  • Conjugate the infinitive using the future subjunctive endings: -es, -mos, -des, -em.
  • Do not conjugate the first and third person singular; they remain identical to the base infinitive.
Subject (Main) + Verb + [Infinitive + Personal Ending] + Subject (Infinitive)

Overview

The Portuguese Personal Infinitive (Infinitivo Pessoal) represents a pivotal grammar concept for B2 learners, allowing precise identification of the subject performing an infinitive's action. Unlike other Romance languages that typically maintain an impersonal infinitive or default to subjunctive clauses, Portuguese uses specific conjugated infinitive forms. This grammatical feature is essential for clarifying meaning, eliminating ambiguity, and constructing complex, nuanced sentences.

Its mastery signifies a significant step towards native-like proficiency and a deeper understanding of Portuguese clause structure.

From a linguistic perspective, the Infinitivo Pessoal is remarkable because it imbues a non-finite verb form (the infinitive) with subject-verb agreement. This fusion allows for an action to be expressed in its basic, tenseless form while simultaneously indicating who is responsible for that action. It serves as a grammatical bridge, preventing the need for a fully conjugated finite clause in many contexts, thereby streamlining sentence construction and enhancing clarity in specific grammatical environments.

For advanced learners, the Infinitivo Pessoal is not merely an optional stylistic choice; it is often grammatically obligatory. It permits intricate sentence structures where a subordinate action's subject differs from the main clause's subject without the full weight of a subordinate clause. Understanding its purpose and application is crucial for anyone aiming to write and speak Portuguese with precision and natural fluency, making it a cornerstone of B2-level competence.

How This Grammar Works

The fundamental role of the Infinitivo Pessoal is to resolve ambiguity. The standard, Impersonal Infinitive (Infinitivo Impessoal), such as falar (to speak), comer (to eat), or dormir (to sleep), refers to an action in a general sense or implies that its subject is either unknown, generic, or identical to the main verb's subject. For instance, in É bom estudar, the act of studying is presented generally, or it refers to the speaker's own action.
However, when the logical subject of the infinitive's action is different from the main clause's subject, and it needs to be explicitly identified, the Infinitivo Pessoal becomes necessary. It functions like a compact, subordinate clause, indicating a specific agent for the infinitive's action without requiring full verb conjugation for tense and mood. Consider the sentence: Comprei os bilhetes para tu ires. (I bought the tickets for you to go.) Here, the main action comprei (I bought) has 'I' as its subject, but the infinitive action ires (to go) clearly specifies 'you' (tu) as its subject.
If the impersonal infinitive ir were used (para ir), the sentence would sound incomplete or imply a generic subject, potentially leading to confusion.
This mechanism allows for an action to remain in its base infinitive form while still signaling person and number. It efficiently conveys subject identity within a dependent phrase, often after prepositions or impersonal expressions. The Infinitivo Pessoal thus transforms what would otherwise be a vague or shared action into a distinct, agent-specific one.
This compact structure contributes to the efficiency and elegance of Portuguese grammar, enabling complex ideas to be expressed concisely without sacrificing clarity.

Formation Pattern

1
The formation of the Infinitivo Pessoal is remarkably regular for most verbs, deriving directly from the Impersonal Infinitive (the dictionary form). You simply append specific personal endings to the infinitive stem. Crucially, the forms for eu (I), você/ele/ela (you/he/she), and the Infinitivo Impessoal are identical, making context or explicit pronoun usage vital for disambiguation in these cases.
2
For regular verbs, the endings are as follows:
3
| Pronoun | Infinitive Ending | falar (to speak) | comer (to eat) | partir (to leave) |
4
| :--- | :--- | :--- | :--- | :--- |
5
| eu | - (base) | falar | comer | partir |
6
| tu | -es | falares | comeres | partires |
7
| você/ele/ela | - (base) | falar | comer | partir |
8
| nós | -mos | falarmos | comermos | partirmos |
9
| vós | -des | falardes | comerdes | partirdes |
10
| vocês/eles/elas | -em | falarem | comerem | partirem |
11
Irregular Verbs also follow this pattern of adding endings to their infinitive stem, but their stems might be irregular. It is paramount to remember that the Infinitivo Pessoal always originates from the Impersonal Infinitive stem, not from a preterite or subjunctive stem, which is a common point of confusion with the Future Subjunctive.
12
Here are some essential irregular verbs and their Infinitivo Pessoal forms:
13
| Verb | eu/você/ele/ela | tu | nós | vós | vocês/eles/elas |
14
| :--- | :--- | :--- | :--- | :--- | :--- |
15
| ser (to be) | ser | seres | sermos | serdes | serem |
16
| estar (to be) | estar | estares | estarmos | estardes | estarem |
17
| ter (to have) | ter | teres | termos | terdes | terem |
18
| vir (to come) | vir | vires | virmos | virdes | virem |
19
| pôr (to put) | pôr | pores | pormos | pordes | porem |
20
Notice the slight stem variations in vir (maintains vir-) and pôr (derived from Latin ponere, hence the o stem, like pores). These irregularities are consistent. When forming compound tenses, it is the auxiliary verb that takes the Infinitivo Pessoal. For example, por teres estudado (for you having studied) uses the Infinitivo Pessoal of ter.

When To Use It

The Infinitivo Pessoal is employed in specific syntactic environments where the subject of the infinitive's action needs to be explicitly defined. Mastering these contexts is key to accurate and natural Portuguese usage. Its primary function is to provide clarity and precision that the impersonal infinitive cannot offer alone.
1. After Prepositions When the Infinitive's Subject Differs from the Main Verb's Subject
This is the most frequent application of the Infinitivo Pessoal. When a preposition (such as para, por, a, de, sem, ao, antes de, depois de, até, apesar de, com) introduces an infinitive phrase whose logical subject is distinct from the main clause's subject, the Infinitivo Pessoal is mandatory.
  • Eles decidiram não ir para não nos atrasarem. (They decided not to go so as not to delay us.) Here, 'they' decided, but 'us' would be delayed.
  • Apesar de tu estares cansado, continuaste. (Despite you being tired, you continued.) The main subject is 'you' (implied in continuaste), and the subject of 'being tired' is also 'you', explicitly stated with the PI for emphasis and grammatical correctness after apesar de.
  • Eu saí sem eles verem. (I left without them seeing.) 'I' left, but 'they' are the ones who didn't see.
2. With Impersonal Expressions
When an impersonal expression (e.g., é bom, é preciso, é necessário, é importante, convém, parece bem) introduces a statement, and the subject of the subsequent infinitive needs clarification, the Infinitivo Pessoal is used. These expressions themselves don't have a personal subject, so the infinitive specifies the agent.
  • É essencial vocês compreenderem a regra. (It's essential for you all to understand the rule.) The rule's understanding is specific to 'you all'.
  • Convém tu fazeres isso logo. (It's advisable for you to do that soon.) 'You' are the one advised to do it.
  • Parece-me bem nós irmos agora. (It seems fine to me for us to go now.) The decision to go affects 'us' specifically.
3. To Avoid Ambiguity and Explicitly Specify Subject
Even in cases where a preposition or impersonal expression isn't strictly present, the Infinitivo Pessoal can be used to ensure there is no doubt about who performs the action of the infinitive, particularly in more formal or precise language. This usage clarifies agency in potentially vague constructions.
  • O chefe elogiou os funcionários por terem terminado o projeto. (The boss praised the employees for having finished the project.) Terem clearly attributes the completion to 'the employees'. Without terem, it might seem ambiguous who finished the project, although context usually helps.
  • O professor queria nós fazermos o trabalho. (The professor wanted us to do the work.) This is a direct construction where nós fazermos specifies the desired subject, often acting as a more concise alternative to que nós fizéssemos (subjunctive).
4. After Certain Causative Verbs
In formal Portuguese, especially European Portuguese, the Infinitivo Pessoal can follow causative verbs like mandar (to order), deixar (to let), or fazer (to make/cause) when their subject is explicitly mentioned after the causative verb.
  • Mandei ele sair. (I ordered him to leave.) Note that sair (for ele) is the same form as the impersonal infinitive, but the explicit pronoun ele clarifies it as Infinitivo Pessoal.
  • Fiz as crianças dormirem mais cedo. (I made the children sleep earlier.) Here, dormirem explicitly states 'the children' as the subject of 'sleeping'.

Common Mistakes

Learners at the B2 level frequently encounter specific challenges with the Infinitivo Pessoal, primarily due to its similarity to other Portuguese verb forms and its nuanced usage contexts. Recognizing these pitfalls and understanding why they occur is critical for true mastery.
1. Confusing it with the Future Subjunctive
This is, by far, the most significant hurdle. For regular verbs (and some irregulars), the Infinitivo Pessoal forms for tu, nós, vós, and eles/elas/vocês are identical to their respective Future Subjunctive forms. The key to differentiation lies in the triggering context and the underlying meaning.
  • The Infinitivo Pessoal is typically triggered by prepositions (para, por, sem, de, antes de, etc.) or impersonal expressions (é bom, é necessário). It indicates the purpose, reason, or condition for the infinitive's action, clearly assigning a subject to that action.
  • The Future Subjunctive is triggered by conjunctions related to future time or condition (se, quando, enquanto, assim que, embora), or by main verbs expressing uncertainty, hypothesis, or dependency on a future event.
Furthermore, the formation of irregular verbs provides a clear distinction:
  • Infinitivo Pessoal irregulars are based on the Impersonal Infinitive stem (e.g., ser -> seres).
  • Future Subjunctive irregulars are based on the 3rd Person Plural of the Preterite stem (e.g., eles foram -> se eu for).
| Feature | Personal Infinitive | Future Subjunctive |
| :--- | :--- | :--- |
| Trigger | Prepositions (para, por, sem, antes de), Impersonal Expr. (é bom, é preciso) | Conjunctions (se, quando, enquanto, assim que), verbs of uncertainty/future condition (esperar que) |
| Meaning | Purpose, reason, condition, clarification of subject for the infinitive's action. | Uncertainty, hypothesis, future condition, dependency on a future event. |
| Irregular Verbs Base | Formed from Impersonal Infinitive stem (ser, ter, vir, pôr). | Formed from 3rd Person Plural Preterite stem (fossem -> for, tiveram -> tiver, vieram -> vier, puseram -> puser). |
| Example (ser) | É importante seres honesto. (It's important for you to be honest.) | Se fores honesto, serás recompensado. (If you are honest, you'll be rewarded.) |
2. Over-conjugating: Using PI when the Subject is the Same
One common error is using the Infinitivo Pessoal when the subject of the infinitive's action is identical to the main verb's subject. In such cases, the Impersonal Infinitive is the correct form.
  • Incorrect: Eu quero ir eu ao cinema. (If I want myself to go.)
  • Correct: Eu quero ir ao cinema. (The subject 'I' is implied for ir).
If the intention is I want you to go, then it's a clause requiring the subjunctive: Eu quero que tu vás ao cinema. While the Infinitivo Pessoal can sometimes replace a subjunctive clause (e.g., É importante tu estudares vs. É importante que tu estudes), it's crucial not to apply it when the main verb's subject is the agent of the infinitive.
3. Incorrect Irregular Forms
Failing to properly form the Infinitivo Pessoal of irregular verbs is another frequent mistake. Learners might attempt to regularize them or confuse their stems with other tenses.
  • Incorrect: Para vinhares cedo. (Mixing vir with regular -ar endings)
  • Correct: Para vires cedo. (Respecting vir's vir- stem).
  • Incorrect: Por pondo a mesa. (Using gerund form)
  • Correct: Por pores a mesa. (Using the correct pôr stem).
Always default to the impersonal infinitive's stem when forming the Infinitivo Pessoal, even for irregular verbs.
4. Ignoring eu/você/ele/ela Forms
The fact that eu, você/ele/ela forms are identical to the Impersonal Infinitive can be confusing. Learners sometimes believe these forms don't exist, or they struggle to use them correctly. The solution is often to explicitly state the pronoun for clarity, especially for eu and você/ele/ela to avoid ambiguity.
  • É importante eu saber a verdade. (It's important for me to know the truth.) The pronoun eu clarifies the subject of saber.
  • Para ele conseguir o emprego, precisa de estudar mais. (For him to get the job, he needs to study more.) ele is explicitly stated.
5. Overlooking Regional Differences (BP vs. EP)
Brazilian Portuguese (BP) and European Portuguese (EP) exhibit different preferences regarding the Infinitivo Pessoal. BP tends to use the Impersonal Infinitive more liberally, often relying on explicit pronouns or subjunctive clauses where EP would strictly use the Infinitivo Pessoal. This can lead to learners from a BP background under-using the form in formal contexts or when aiming for EP fluency.
  • EP: Para fazermos o jantar...
  • BP (informal): Para a gente fazer o jantar... or Para nós fazer o jantar... (less formal, but common in speech).
However, in formal writing across both variants, the Infinitivo Pessoal remains essential for grammatical precision.

Real Conversations

The Infinitivo Pessoal is not just a theoretical construct; it is a vital component of natural, precise communication in Portuguese, particularly when moving beyond basic sentences. Its usage varies subtly between formal and informal registers, and between European and Brazilian Portuguese.

In formal contexts, such as academic writing, official reports, or professional emails, the Infinitivo Pessoal is almost always employed correctly, especially after prepositions. It demonstrates a high level of grammatical accuracy and clarity.

- Work Email (EP/Formal BP): A fim de evitarmos futuros problemas, solicitamos que todos os departamentos revejam os seus procedimentos. (In order for us to avoid future problems, we request that all departments review their procedures.) The Infinitivo Pessoal evitarmos precisely assigns the action of avoiding to 'us'.

In casual conversation, particularly in Brazilian Portuguese, there's a more flexible approach. While Infinitivo Pessoal for tu, vocês, and eles/elas is common, the nós form sometimes gets replaced by a gente + Impersonal Infinitive.

- Casual BP: A gente pode ir lá pra a gente ver o que acontece. (We can go there for us to see what happens.) Here, a gente ver (impersonal infinitive with explicit subject) is used instead of para nós vermos.

- Casual EP: Para tu ires ver, é melhor saíres já. (For you to go see, it's better you leave now.) The tu form is regularly used.

In texting and social media, brevity often leads to simplified structures. In BP, explicit pronouns with the impersonal infinitive are very common. In EP, while informal, the Infinitivo Pessoal is still more prevalent than in BP.

- WhatsApp (BP): Pra vc ir amanhã, né? (For you to go tomorrow, right? - using vc (você) and impersonal ir).

- WhatsApp (EP): Para tu ires amanhã, levas a chave. (For you to go tomorrow, take the key.)

When discussing obligations or advice, especially from an authority figure (parent, teacher), the Infinitivo Pessoal can soften the imperative by framing it as a necessary action for the specific individual.

- É importante vocês estudarem para o exame. (It's important for you all to study for the exam.) This sounds like a piece of advice or statement of fact, rather than a direct command.

Understanding these nuances helps you adapt your language to different social contexts and sound more authentic, regardless of the Portuguese variant you primarily use.

Quick FAQ

Q: Is the Infinitivo Pessoal always mandatory?

In formal Portuguese, particularly in European Portuguese and formal Brazilian Portuguese, using the Infinitivo Pessoal after prepositions when the infinitive's subject differs from the main verb's subject is generally mandatory for grammatical correctness. In informal Brazilian Portuguese, other constructions (e.g., explicit pronoun + impersonal infinitive) might be used in speech, but the Infinitivo Pessoal always adds precision and grammatical accuracy.

Q: Can I replace the Infinitivo Pessoal with a subjunctive clause?

Often, yes. Many instances where the Infinitivo Pessoal is used could technically be rephrased using a que clause followed by the subjunctive. For example, É importante tu estudares (Personal Infinitive) is functionally equivalent to É importante que tu estudes (Subjunctive). The Infinitivo Pessoal is usually more concise and considered more elegant in many contexts. The choice often depends on desired formality, regional preference, and sentence flow.

Q: Why do eu, você, ele, ela forms have no specific endings for the Infinitivo Pessoal?

Their forms are identical to the bare Impersonal Infinitive. This is a feature of Portuguese's historical evolution, where these singular forms retained the simpler, uninflected infinitive. Context, and often the explicit presence of the pronoun (e.g., Para eu fazer, Para ele comer), clarifies the specific subject, especially to avoid ambiguity with a generic or main-clause subject.

Q: How do I distinguish Infinitivo Pessoal from Future Subjunctive when they look identical?

The crucial distinction lies in their triggering conjunctions or prepositions and the semantic context. If the verb form follows a preposition (e.g., para, por, sem) or an impersonal expression (é bom, é preciso), it's almost certainly the Infinitivo Pessoal. If it follows a conjunction like se (if), quando (when), assim que (as soon as), or expresses uncertainty/conditionality in the future, it's the Future Subjunctive. Additionally, remember the distinct irregular verb stems for each (Impersonal Infinitive stem for PI vs. 3rd Person Plural Preterite stem for Future Subjunctive).

Q: Does the vós form still matter?

In Brazil, the vós form is almost entirely archaic and absent from daily speech. In Portugal, it is still encountered in very specific formal contexts, such as religious texts, legal documents, or highly ceremonial speech. For most learners, focusing on the vocês form for the second-person plural is sufficient for modern communication, as it has largely replaced vós in common usage across both variants of Portuguese.

Q: What's the main benefit of mastering the Infinitivo Pessoal?

Mastering the Infinitivo Pessoal significantly enhances your ability to construct grammatically precise and unambiguous sentences. It allows you to clearly assign agency to actions within dependent phrases, reducing potential confusion and enabling more sophisticated expression. It is a hallmark of advanced Portuguese proficiency, contributing to both clearer communication and a more natural, idiomatic command of the language.
