Antes que: The 'Beat the Clock' Connector (Subjunctive)
antes que + Subjunctive when one action races to beat another involving a different subject.
Grammar Rule in 30 Seconds
Use 'antes que' followed by the subjunctive to describe an action that must happen before another future or hypothetical event.
- Always use the subjunctive after 'antes que' when referring to the future: 'Saia antes que chova.'
- If the subject is the same, use 'antes de' + infinitive: 'Vou sair antes de comer.'
- Never use the indicative after 'antes que' if the event hasn't happened yet.
Overview
In Portuguese, conveying one action preceding another, particularly a potential or preventable event, requires precision. The conjunction antes que serves this exact purpose, acting as a temporal connector meaning "before." However, unlike its English equivalent, antes que does not simply link two events; it fundamentally changes the mood of the verb in the dependent clause to the Subjunctive. This grammatical shift is crucial for B2 learners to master, as it underpins a core principle of Portuguese syntax: the distinction between established facts and anticipated, hypothetical, or desired realities.
At its core, antes que signals a relationship where the action in the main clause occurs with the conscious intent of preceding, preventing, or preparing for the action described in the subordinate clause. Consider the difference between Ele saiu antes que ela chegasse (He left before she arrived) and a simple statement of fact. The use of the Subjunctive chegasse immediately tells the listener that her arrival was a projected event at the time of his departure, not a certainty.
This contrasts sharply with English, which often uses the indicative. Understanding this inherent uncertainty or non-factual nature of the dependent event is the first step toward grasping the why behind antes que's consistent demand for the Subjunctive mood. It's the grammar of strategic timing and projected outcomes.
How This Grammar Works
antes que with the Subjunctive is the inherent lack of certainty of the subordinate clause's event at the main action's moment. The verb in the antes que clause describes an event that is either anticipated, wished for, feared, or specifically acted upon to prevent its occurrence. Because this event has not yet solidified into a concrete fact, Portuguese grammar mandates the Subjunctive mood, the mood of doubt, desire, emotion, and indefiniteness.antes que, you are establishing a temporal dependency where the main action is performed in view of the subordinate action. The event in the antes que clause is often a potential future occurrence relative to the main verb, even if the entire sentence describes past events. For instance, in Eles correram antes que a chuva começasse (They ran before the rain started), começasse (Imperfect Subjunctive) indicates that at the time they ran, the rain's beginning was merely a potentiality, an anticipated event that might or might not happen.Antes que is a prime example of a conjunction that inherently signals this condition of projected reality or potentiality. It is not about when something happened relative to a fixed timeline, but about the speaker's perception of the certainty of the second event's occurrence from the vantage point of the first.Formation Pattern
antes que follows a precise grammatical pattern, essential for conveying anticipatory or preventive actions. Adhering to this structure ensures clarity and correctness in Portuguese. The pattern is as follows:
antes que + Subordinate Clause (Verb in Subjunctive Mood)
antes que: This is the fixed conjunction. It must always include que. Omitting it (*antes ele saia) creates an ungrammatical phrase because antes alone functions as an adverb, not a conjunction that can introduce a clause.
Eu saio (I leave) | Present Subjunctive | que ela chegue (that she arrives) | Eu saio antes que ela chegue. (I leave before she arrives.) |
Ele estudará (He will study) | Present Subjunctive | que o teste comece (that the test begins) | Ele estudará antes que o teste comece. (He will study before the test begins.) |
Fecha a porta (Close the door) | Present Subjunctive | que o vento entre (that the wind enters) | Fecha a porta antes que o vento entre. (Close the door before the wind comes in.) |
Fazer (to do/make) in Present Subjunctive
faça | Vou fazer café antes que eu faça outra coisa. |
faças | Tu deves verificar antes que tu faças o pedido. |
faça | Ela quer chegar antes que ele faça perguntas. |
façamos | Precisamos almoçar antes que nós façamos a reunião. |
façais | Vós deveis sair antes que vós façais algo errado. |
façam | Eles ligarão antes que eles façam a viagem. |
vós form is primarily used in European Portuguese (EP). In Brazilian Portuguese (BP), vocês is used instead, taking the eles/elas form (façam).
Eu saí (I left) | Imperfect Subjunctive | que ela chegasse (that she arrived) | Eu saí antes que ela chegasse. (I left before she arrived.) |
Ele estudava (He was studying) | Imperfect Subjunctive | que o teste começasse (that the test began) | Ele estudava antes que o teste começasse. (He was studying before the test began.) |
Eu faria (I would do) | Imperfect Subjunctive | que ele perguntasse (that he asked) | Eu faria isso antes que ele perguntasse. (I would do that before he asked.) |
Chegar (to arrive) in Imperfect Subjunctive
chegasse | Eu saí antes que eu chegasse atrasado. |
chegasses | Tu tinhas que te apressar antes que tu chegasses tarde. |
chegasse | Ela limpou antes que ele chegasse em casa. |
chegássemos | Nós fomos antes que nós chegássemos à noite. |
chegásseis | Vós partistes antes que vós chegásseis ao fim. |
chegassem | Eles pediram antes que eles chegassem sem lugar. |
antes que with the same subject, it is almost universally more natural and idiomatic to use antes de + Infinitive in such cases. This distinction is crucial for sounding natural and fluent.
When To Use It
antes que + Subjunctive applies whenever an action precedes, prevents, or prepares for a potential event. It's about the intent behind the temporal order: a deadline, desired outcome, or avoidance. Mastering its usage allows you to articulate these nuanced temporal and conditional relationships.antes que to describe an action taken to actively prevent another event from happening, or to safeguard against a potential negative outcome. The main action serves as a protective measure.Vamos sair de casa antes que a chuva comece.(Let's leave home before the rain starts.) – The intent is to avoid getting wet.Fecha o cofre antes que alguém o veja aberto.(Close the safe before someone sees it open.) – The action prevents potential theft or exposure.Eu sempre verifico os ingredientes antes que os compre.(I always check the ingredients before I buy them.) – A proactive measure to ensure suitability.
Antes que is indispensable for expressing actions that must be completed within a specific timeframe or prior to an impending event. It highlights urgency or a temporal constraint.Tens de entregar o projeto antes que o prazo expire.(You have to submit the project before the deadline expires.) – Emphasizes the fixed deadline.Janta antes que escureça e as lojas fechem.(Have dinner before it gets dark and the shops close.) – Connects dinner to the closing of shops.Vou acabar este capítulo antes que a bateria do portátil acabe.(I'm going to finish this chapter before the laptop battery dies.) – A personal race against time.
Preparei o jantar antes que os convidados chegassem.(I prepared dinner before the guests arrived.) – The preparation is in anticipation of their arrival.Aqueça o forno antes que você coloque o bolo.(Heat the oven before you put the cake in.) – A necessary preliminary step.Vou revisar o material antes que a aula comece.(I will review the material before class begins.) – An act of academic preparation.
antes que with the Subjunctive naturally fits. It underscores the hypothetical nature of the event being preceded.Devemos agir antes que a situação piore ainda mais.(We should act before the situation worsens even more.) – The worsening is a feared possibility.Guarda a tua carteira antes que a percas na multidão.(Put away your wallet before you lose it in the crowd.) – Loss is a potential, undesirable outcome.
Common Mistakes
antes que presents pitfalls for learners, often due to English interference or misunderstanding the Subjunctive. Awareness of these errors is key to fluency.- Incorrect:
*Eu vou sair antes que ele chega.(I will leave before he arrives.) - Correct:
Eu vou sair antes que ele chegue.(I will leave before he arrives.) - Why it's wrong: Using
chega(Present Indicative) implies that his arrival is a certainty, an established fact, at the moment you are talking about leaving. This contradicts the very purpose ofantes que, which introduces an event that is anticipated, potential, or to be prevented – hence, non-factual from the perspective of the main clause. The Indicative expresses certainty, while the Subjunctive expresses uncertainty, desire, or possibility.
antes que with antes de + Infinitive:antes que when antes de + Infinitive would be the idiomatic and grammatically simpler choice. This occurs when the subject of both the main and subordinate clauses is the same.- Incorrect (though technically not ungrammatical, it's clunky):
*Eu como antes que eu saia.(I eat before I leave.) - Correct:
Eu como antes de sair.(I eat before leaving/before I leave.) - Why it's wrong (stylistically): While
antes que eu saiais grammatically permissible (as the Subjunctive is used), it sounds unnatural and overly formal to native speakers when the subject doesn't change. The constructionantes de+ Infinitive is the standard, concise, and elegant solution for same-subject actions. Reserveantes que+ Subjunctive primarily for instances with different subjects.
- Incorrect:
Ele saiu antes que ela chegue.(He left before she arrives [Present Subjunctive].) - Correct:
Ele saiu antes que ela chegasse.(He left before she arrived [Imperfect Subjunctive].) - Why it's wrong: The main verb
saiuis in the past (Pretérito Perfeito). The action in theantes queclause (chegasse) must also reflect a past potentiality relative tosaiu, which is achieved with the Imperfect Subjunctive. Using the Present Subjunctive (chegue) creates a temporal mismatch, as it implies a future potentiality from a past action.
que from antes que:que, treating antes as a standalone conjunction.- Incorrect:
*Antes ele chegue, vou arrumar.(Before he arrives, I will tidy up.) - Correct:
Antes que ele chegue, vou arrumar.(Before he arrives, I will tidy up.) - Why it's wrong:
Antesis an adverb ("beforehand," "previously") and cannot introduce a subordinate clause in this manner. The composite conjunctionantes queis required to introduce the Subjunctive clause.
Real Conversations
The utility of antes que + Subjunctive permeates everyday Portuguese communication across registers. From quick messages to more deliberate conversations, this structure allows speakers to convey urgency, prevention, or anticipation naturally.
In Texting and Social Media (Brazilian Portuguese examples):
- Corre, amiga, antes que esgote! (Run, friend, before it sells out!) – Urgent warning about limited stock.
- Posta isso antes que eu mude de ideia. (Post this before I change my mind.) – Expressing a fleeting decision.
- Manda a localização antes que a gente se perca. (Send the location before we get lost.) – Proactive measure to avoid a problem.
In Work and Formal Contexts (European Portuguese examples):
- Por favor, assegure-se de que o relatório seja concluído antes que o prazo seja excedido. (Please ensure the report is completed before the deadline is exceeded.) – Formal instruction for compliance.
- A equipa deve rever os protocolos antes que implementemos a nova política. (The team must review the protocols before we implement the new policy.) – Strategic planning and phased implementation.
- Vou enviar o e-mail antes que a gerente me peça. (I will send the email before the manager asks me.) – Proactive work management.
In Casual Conversation (General Portuguese examples):
- Vamos embora antes que chova forte. (Let's go before it rains heavily.) – Avoiding an undesirable weather outcome.
- Ele sempre liga para a mãe antes que ela se preocupe. (He always calls his mother before she worries.) – Explaining a habitual, preventative action.
- Come o teu gelado antes que derreta todo. (Eat your ice cream before it all melts.) – A friendly, gentle warning.
These examples illustrate antes que as a fundamental Portuguese linguistic tool, expressing complex temporal and conditional relationships effectively. It reflects a cultural tendency to be precise about the reality status of dependent events, emphasizing whether an action is factual or merely potential.
Quick FAQ
antes que + Subjunctive.antes que always followed by the Subjunctive?Yes, absolutely. This is a non-negotiable rule in Portuguese. The very nature of antes que introduces a clause whose event is potential, anticipated, or prevented, thus consistently triggering the Subjunctive mood. There are no exceptions where antes que would legitimately take the Indicative.
antes que clause never actually happens?That is precisely the strength and purpose of the Subjunctive here. The Subjunctive expresses potentiality, desire, or hypothesis, not established fact. So, if you say Escondi o bolo antes que ele o visse (I hid the cake before he saw it), the implication is that he didn't see it, and your action prevented the seeing. The Subjunctive perfectly captures this counterfactual or prevented outcome.
antes que?The grammatical rule itself – antes que always requires the Subjunctive – is consistent across both major variants of Portuguese. The main differences you might encounter are in verb conjugations (e.g., the vós form in EP vs. its near absence in BP) and potentially some lexical preferences, but the core syntactic structure remains the same.
antes que be used if the subject of both clauses is the same?Grammatically, yes, it's possible (Eu saí antes que eu chegasse atrasado). However, it is overwhelmingly more natural and idiomatic to use antes de + Infinitive when the subject is the same in both clauses (Eu saí antes de chegar atrasado). This distinction is crucial for sounding like a native speaker. Antes que truly shines when there are two different subjects interacting.
antes que compare to depois que (after)?While both are temporal conjunctions, their Subjunctive triggers differ. Depois que often takes the Indicative if the event in the subordinate clause is presented as a definite, completed fact (Depois que ele chegou, comemos). However, if the event is still future or uncertain relative to the main clause, depois que can also take the Subjunctive (Depois que ele chegue, avisarei). Antes que, by contrast, always demands the Subjunctive due to the inherent uncertainty/potentiality of the event it introduces.
