The Subjunctive Trigger Words (Conjunctions)
Grammar Rule in 30 Seconds
Certain conjunctions force the verb into the subjunctive mood because they express uncertainty, purpose, or conditions that haven't happened yet.
- Use 'para que' (so that) to express purpose: 'Estudo para que você aprenda.'
- Use 'embora' (although) for concession: 'Embora chova, sairemos.'
- Use 'antes que' (before) for future time: 'Saia antes que ele chegue.'
Overview
In Portuguese, mastering the subjunctive mood is crucial for expressing nuance beyond simple factual statements. While previous discussions highlighted its use with doubt, emotions, and impersonal expressions, the subjunctive also plays a non-negotiable role when introduced by specific conjunctions. These conjunctions act as grammatical triggers, signaling that the following clause presents an action or state as hypothetical, conditional, purposeful, concessive, or desired, rather than as a concrete fact.
Consequently, the verb within this dependent clause must shift from the indicative to the subjunctive mood. This linguistic mechanism reflects a fundamental aspect of Portuguese: the mood of a verb is determined not just by the speaker's attitude but often by the structural elements that introduce its clause. Understanding these triggers is paramount for B2 learners to articulate complex thoughts, engage in sophisticated argumentation, and navigate the subtleties of native communication.
Think of these conjunctions as traffic signals: they direct the grammatical flow, dictating a mood change to accurately convey the speaker's perspective on the subordinate action. For instance, stating "He studies" (Ele estuda) is a simple fact using the indicative. However, if you add purpose, such as "so that he learns," the verb aprender must become aprenda in the subjunctive: para que ele aprenda.
The conjunction para que inherently introduces intention, a non-factual state, thereby demanding the subjunctive. This consistent application of the subjunctive after specific conjunctions is a cornerstone of Portuguese syntax, ensuring clarity in complex sentence structures.
How This Grammar Works
para que (purpose), embora (concession), or caso (condition) inherently frame the subordinate action as something intended, hypothesized, conceded, or not yet realized.Ele trabalha para que a família viva bem (He works so that the family may live well) expresses intention.Ele trabalha para que a família vive bem, it would sound jarring and grammatically flawed because the conjunction para que demands the subjunctive to correctly express purpose. The structure is always Main Clause + Conjunction + Subjunctive Verb.Formation Pattern
eu) form of the Present Indicative. The process involves dropping the -o ending and adding specific new endings based on the verb's conjugation group.
eu form of the Present Indicative.
-o ending.
falar (to speak)
eu falo (Present Indicative) -> fal- -> que eu fale, que tu fales, que ele/ela/você fale, que nós falemos, que vós faleis, que eles/elas/vocês falem.
comer (to eat)
eu como (Present Indicative) -> com- -> que eu coma, que tu comas, que ele/ela/você coma, que nós comamos, que vós comais, que eles/elas/vocês comam.
partir (to leave/depart)
eu parto (Present Indicative) -> part- -> que eu parta, que tu partas, que ele/ela/você parta, que nós partamos, que vós partais, que eles/elas/vocês partam.
eu form, which then carries over to their subjunctive conjugation. These must be memorized.
eu (Present Indicative) | que eu (Present Subjunctive) | que ele/ela/você (Present Subjunctive) | que nós (Present Subjunctive) | que eles/elas/vocês (Present Subjunctive) |
ser | sou | seja | seja | sejamos | sejam |
estar | estou | esteja | esteja | estejamos | estejam |
ir | vou | vá | vá | vamos | vão |
ter | tenho | tenha | tenha | tenhamos | tenham |
haver | hei | haja | haja | hajamos | hajam |
fazer | faço | faça | faça | façamos | façam |
poder | posso | possa | possa | possamos | possam |
querer | quero | queira | queira | queiramos | queiram |
saber | sei | saiba | saiba | saibamos | saibam |
vir | venho | venha | venha | venhamos | venham |
dar | dou | dê | dê | demos | deem |
dizer | digo | diga | diga | digamos | digam |
trazer | trago | traga | traga | tragamos | tragamos |
para que, embora, or caso, the verb immediately following it, within the subordinate clause, must be conjugated into one of these Present Subjunctive forms. The presence of que is a strong indicator, but not all que clauses trigger the subjunctive (e.g., Eu sei que ele vem - indicative). With these specific trigger conjunctions, however, the subjunctive is mandatory.
When To Use It
para que(so that, in order that)a fim de que(in order that – more formal thanpara que)de modo que / de forma que(so that, in such a way that – when expressing purpose or intention, not factual result)
Estudo muito para que passe no exame.(I study a lot so that I pass the exam.)Ele se esforça a fim de que seus filhos tenham uma boa educação.(He strives so that his children have a good education.)Organizamos o evento de forma que todos se sintam incluídos.(We organize the event in such a way that everyone feels included.)
para + infinitive (or a fim de + infinitive), not para que + subjunctive.- Different subjects:
Eu te ajudo para que tu aprendas.(I help you so that you learn.) - Same subject:
Eu estudo para aprender.(I study to learn.) — NotEu estudo para que eu aprenda.
embora(although, even though)ainda que(even if, even though)mesmo que(even if, even though)posto que / conquanto(although – more formal/literary)
Embora chova, vamos caminhar na praia.(Even though it rains, we're going to walk on the beach.)Ainda que ele seja rico, não é feliz.(Even if he is rich, he isn't happy.)Mesmo que tu não queiras, tens de ir.(Even if you don't want to, you have to go.)
caso(in case, provided that)contanto que(provided that, as long as)desde que(provided that, as long as – distinguish from temporaldesde que)a menos que / a não ser que(unless)salvo se(unless, except if)sem que(without – implies an unexpected or undesirable lack of action, often a negative condition)
Leva um casaco caso faça frio.(Take a jacket in case it's cold.)Posso emprestar-te o livro contanto que devolvas amanhã.(I can lend you the book provided that you return it tomorrow.)Você terá sucesso desde que se esforce.(You will succeed as long as you make an effort.)Não sairei a menos que me digas a verdade.(I won't leave unless you tell me the truth.)Ele saiu sem que ninguém o visse.(He left without anyone seeing him.)
desde que: When desde que means "since" (referring to time), it uses the indicative: Desde que cheguei, não vi nada. (Since I arrived, I haven't seen anything.) When it means "provided that" (condition), it uses the subjunctive: Desde que estudes, passarás. (Provided that you study, you will pass.)quando, depois que), some inherently imply anticipation or a pre-condition using the Present Subjunctive.antes que(before)até que(until – when the action is anticipated or dependent on a future event)
Termina o trabalho antes que anoiteça.(Finish the work before it gets dark.)Esperarei até que ele chegue.(I will wait until he arrives.)
até que with the indicative implies a factual duration or completed action in the past/present: Esperou até que ele chegou. (He waited until he arrived - implies he actually arrived).Common Mistakes
para que. Remember the rule: different subjects = subjunctive, same subject = infinitive.- ❌ Incorrect:
Eu ligo para tu saber.(I call for you to know.) - Explanation: The subject of
ligariseu, and the subject ofsaberistu. Subjects are different, so the subjunctive is required. - ✅ Correct:
Eu ligo para que tu saibas.(I call so that you know.) - ✅ Correct (same subject):
Eu ligo para saber.(I call to know.)
Se vs. Caso Confusion:Caso always triggers the Present Subjunctive for the condition, whereas se typically uses the Indicative for real conditions, or the Imperfect/Future Subjunctive for hypothetical/future conditions.- ❌ Incorrect:
Caso tiver dúvidas...(Using Future Subjunctivetiveraftercaso) - ✅ Correct:
Caso tenhas dúvidas, pergunta.(In case you have doubts, ask.) - Compare with
se: Se tens dúvidas, pergunta.(If you have doubts, ask. - Real condition, Indicative)Se tiveres dúvidas, pergunta.(If you have doubts, ask. - Future condition, Future Subjunctive)
embora or ainda que. This is grammatically incorrect in formal contexts and can sound uneducated.- ❌ Incorrect (colloquial BP):
Embora ele está cansado, vai trabalhar. - ✅ Correct (EP and formal BP):
Embora ele esteja cansado, vai trabalhar.(Even though he is tired, he will work.)
desde que with Conditional desde que:Desde que can mean "since" (time) or "provided that" (condition). The meaning dictates the mood.- Temporal (
since) = Indicative: Desde que chegamos, não parou de chover.(Since we arrived, it hasn't stopped raining.)- Conditional (
provided that) = Subjunctive: Podes ir, desde que me digas onde vais.(You can go, provided that you tell me where you're going.)
ser, estar, ter, and ir.- ❌ Incorrect:
...para que ele ser feliz. - ✅ Correct:
...para que ele seja feliz.
Real Conversations
Understanding how these subjunctive triggers are used in authentic communication is vital for B2 learners. Beyond textbook examples, the structures appear naturally across various registers of Portuguese.
1. Texting and Social Media (Informal):
Even in informal digital communication, the subjunctive remains crucial for clarity, though some abbreviations or slight colloquialisms might appear.
- Mando-te o link pra q vejas. (BP for para que vejas) - Sending you the link so you see it.
- Tudo bem, msm q chegues atrasado. (mesmo que chegues) - It's fine, even if you arrive late.
- Qq coisa avisa, caso precises. (qualquer coisa avisa, caso precises) - Let me know anything, in case you need it.
2. Work Emails and Professional Communication (Formal):
In professional settings, precise use of the subjunctive is expected to convey politeness, intention, and specific conditions.
- Anexei o documento a fim de que V. Exa. possa revisar. - I have attached the document so that Your Excellency may review it.
- Certifique-se de que o relatório esteja completo antes que o envie. - Make sure the report is complete before you send it.
- A reunião será adiada a não ser que todos os participantes confirmem. - The meeting will be postponed unless all participants confirm.
3. Casual Conversation:
Native speakers seamlessly integrate these structures. Listen for the que and the mood shift.
- (EP): Embora esteja frio, apetece-me ir à esplanada. - Even though it's cold, I feel like going to the outdoor café.
- (BP): Ele sempre fala baixo para que ninguém o ouça. - He always speaks softly so that no one hears him.
- Podes ficar em minha casa contanto que ajudes com as tarefas. - You can stay at my place provided that you help with the chores.
Cultural Insight
para que or a fim de que in requests or directives can often soften the tone, making them sound less direct and more polite, by framing the action as a beneficial outcome rather than a command. For instance, Por favor, complete este formulário para que possamos processar o seu pedido (Please complete this form so that we can process your request) is more courteous than a direct command.Quick FAQ
The conjunctions that trigger the subjunctive inherently introduce a clause that expresses non-factuality, subjectivity, contingency, or intention concerning the action. The subjunctive is the mood of unreality, hypothesis, desire, or opinion. Conjunctions that express certainty, direct cause-and-effect, or simple temporal sequence without anticipation usually take the indicative.
quando (when)? Does it take the Present Subjunctive?For future events, quando takes the Future Subjunctive, not the Present Subjunctive. Example: Quando eu for ao Brasil, visito-te. (When I go to Brazil, I'll visit you.) If referring to a habitual or past event, quando takes the Indicative: Quando ele fala, eu ouço. (When he speaks, I listen.) Our current trigger words, however, mandate the Present Subjunctive.
para que and a fim de que?Yes, a fim de que is generally more formal and less common in everyday spoken Portuguese, especially in Brazil. Para que is universally used across all registers, from casual to formal. You will often encounter a fim de que in written documents, academic texts, or very formal speeches.
pra instead of para que?In highly informal contexts, particularly in Brazilian Portuguese, para que is often reduced to pra que or even just pra. The grammatical rule for the subjunctive, however, still applies. The mood is governed by the underlying conjunction's function, not its abbreviation: Estudo pra que aprenda mais rápido. (I study so that I learn faster.)
Generally, yes, the core grammatical rules for these subjunctive triggers are the same in both variants. The main difference might be in frequency of use (e.g., a fim de que might be slightly more common in formal EP than BP) and the occasional informal colloquialism in BP where the indicative might be heard incorrectly with conjunctions like embora, as discussed in "Common Mistakes." Always adhere to the subjunctive for formal and grammatically correct usage in both variants.
