If I Have Time: The Future Subjunctive of 'Ter' (tiver)
tiver to express future conditions or timing involving 'having' something when the outcome is still uncertain.
Grammar Rule in 30 Seconds
Use 'tiver' instead of 'ter' when talking about a future condition that depends on having something.
- Use 'tiver' for 'if I/he/she/you have' (e.g., 'Se eu tiver tempo').
- Use 'tiverem' for 'if they/you all have' (e.g., 'Se eles tiverem dinheiro').
- Always use the future subjunctive after 'se' (if) or 'quando' (when) for future events.
Overview
The Portuguese Future Subjunctive of ter (to have), specifically the form tiver, is a critical grammatical construction for B1-level learners and beyond. It serves to express a future condition or a future temporal circumstance related to the act of 'having,' where the fulfillment of that condition is uncertain or yet to occur. Unlike the Present Indicative, which describes factual or habitual occurrences, or the Present Subjunctive, which conveys desires or doubts about the present, the Future Subjunctive inherently projects into the future, signaling contingency.
Mastering tiver allows you to articulate nuanced future scenarios in Portuguese that English often conveys with the simple present tense. For instance, while in English you might say "If I have time...", Portuguese requires Se eu tiver tempo... to correctly convey the conditional and uncertain nature of 'having' that time in the future. This grammatical precision is fundamental for sounding natural and communicating effectively, as it reflects a core linguistic mechanism for managing expectations and possibilities.
How This Grammar Works
Se(if): Introduces a conditional clause. Example:Se você tiver dúvidas, me pergunte.(If you have doubts, ask me.) Here, the act of asking depends on the future possibility of having doubts.Quando(when): Introduces a temporal clause, referring to a future moment. Example:Quando eu tiver o relatório, enviarei.(When I have the report, I will send it.) The sending is contingent on the future possession of the report.Assim que(as soon as): Similar toquando, emphasizing immediacy after a future event. Example:Assim que ele tiver a resposta, nos avisará.(As soon as he has the answer, he will let us know.)Enquanto(while, as long as): Indicates a duration contingent on a future state. Example:Enquanto tivermos paciência, tudo ficará bem.(As long as we have patience, everything will be fine.)
ter is particularly common in this construction due to the frequent need to discuss future possession, availability, or circumstance.Formation Pattern
ter is irregular, diverging from the typical pattern for regular -er verbs where the Future Subjunctive often mirrors the infinitive form. Instead, ter derives its Future Subjunctive stem from the Pretérito Perfeito Indicativo (Simple Past Indicative).
ter:
ter, this form is tiveram (they had).
-am ending: Removing -am from tiveram yields the stem tiv-.
tiv- stem.
ter in the Future Subjunctive:
I) | - | tiver |
You sing., informal) | -es | tiveres |
He/She/You sing., formal) | - | tiver |
We) | -mos | tivermos |
You plur., informal/archaic) | -des | tiverdes |
They/You plur., formal) | -em | tiverem |
eu, ele/ela, and você. Context and subject pronouns are crucial for disambiguation. For example, Se eu tiver um carro... (If I have a car...) versus Se ele tiver um carro... (If he has a car...).
tu (tiveres) and vós (tiverdes) forms are common in European Portuguese but less frequent in Brazilian Portuguese, especially in casual spoken language where você and vocês are predominantly used for second-person references, defaulting to the você/vocês forms of the verb.
i in tiver is a crucial identifier for this tense, distinguishing it from the infinitive ter and the Present Subjunctive tenha.
When To Use It
ter is employed in subordinate clauses where the act of 'having' is a future condition or a temporal reference point that must be met for the action in the main clause to occur. Its usage is highly dependent on specific conjunctions that introduce these contingent clauses.- 1Conditional Clauses with
se(if): This is perhaps its most common application. It sets up a hypothetical future scenario involving possession, availability, or a state of being. The condition is not yet fulfilled and may or may not happen.
Se eu tiver tempo amanhã, te ligo.(If I have time tomorrow, I'll call you.) — The call is conditional on future time availability.Eles não vão sair se não tiverem o ingresso.(They won't leave if they don't have the ticket.) — Their departure is contingent on future ticket possession.Se tivermos sorte, encontramos um bom lugar.(If we are lucky, we'll find a good spot.) — Finding a spot depends on future luck.
- 1Temporal Clauses with
quando(when),assim que(as soon as),depois que(after),enquanto(while/as long as),até que(until): These conjunctions introduce clauses that specify a future time at which the main action will take place, contingent on the 'having' event.
Quando você tiver idade, poderá viajar sozinho.(When you are old enough, you can travel alone.) — Traveling depends on reaching a future age.Assim que ele tiver a confirmação, começaremos.(As soon as he has the confirmation, we will start.) — Starting is immediate upon future confirmation.Vou esperar até que eu tiver tudo pronto.(I will wait until I have everything ready.) — The waiting period ends when future readiness is achieved.Você pode usar o carro enquanto tiver combustível.(You can use the car as long as it has fuel.) — Car usage is conditional on future fuel presence.
- 1Clauses of Purpose or Concession (less common but possible): Sometimes, though less directly, it can appear in clauses expressing purpose or concession when that purpose or concession relates to a future contingent 'having'.
Ela estuda muito para que, quando tiver a oportunidade, possa viajar.(She studies a lot so that, when she has the opportunity, she can travel.)
- 1Implicit Conditions: In some contexts, particularly in spoken language, the trigger word might be omitted, but the conditional or temporal nature remains clear from context.
Você não pode reclamar. Tiver dinheiro, compra.(You can't complain. If you have money, buy it.) – Here,seis implied.
ter signals that the event of 'having' is not a certainty but a possibility or a prerequisite that lies ahead in time. This makes it distinct from:- The Present Indicative of
ter(tenho), which describes current or habitual possession/states:Eu tenho um carro.(I have a car.) orQuando tenho tempo, leio.(When I have time [habitually], I read.) - The Present Subjunctive of
ter(tenha), which expresses wishes, doubts, emotions, or commands related to current or general states of 'having':Espero que você tenha um bom dia.(I hope you have a good day.)
Common Mistakes
ter. Understanding these common errors and their underlying reasons is crucial for achieving fluency and accuracy.- 1Confusing
se eu tenhowithse eu tiver: This is the most prevalent error for English speakers. In English, we use the simple present for future conditions ("If I have time"). In Portuguese,se eu tenhoimplies a factual, habitual, or certain present condition.
- Incorrect:
Se eu tenho tempo amanhã, te ligo.(Implies: If I always have time tomorrow, which is illogical, or if I definitely have time, which removes the contingency). - Correct:
Se eu tiver tempo amanhã, te ligo.(Implies: If the future condition of 'having time' materializes, I will call you.)
Se + Indicative for facts/habits; Se + Future Subjunctive for future possibilities.- 1Using the infinitive
terinstead oftiver: Some learners, aware that some regular verbs' Future Subjunctive forms look like their infinitives (e.g.,falar->quando eu falar), mistakenly apply this toter.
- Incorrect:
Quando eu ter o resultado, aviso. - Correct:
Quando eu tiver o resultado, aviso.
Ter is an irregular verb, and its Future Subjunctive stem tiv- must be used. Always remember the i in tiver.- 1Mixing up
tiverwithtenha(Present Subjunctive): While both are subjunctive moods, their temporal focus differs.
Tenha(Present Subjunctive) expresses wishes, doubts, or emotions about the present or a general state:Espero que você tenha saúde.(I hope you have health.)Tiver(Future Subjunctive) expresses a condition or temporal event in the future:Se você tiver saúde, viajará.(If you have health [in the future], you will travel.)
- 1Mixing up
tiverwithtivesse(Imperfect Subjunctive): These forms are distinct in meaning and usage.
Tivesse(Imperfect Subjunctive) refers to hypothetical, counterfactual, or past conditions:Se eu tivesse dinheiro, compraria um carro.(If I had money [but I don't], I would buy a car.)Tiver(Future Subjunctive) refers to a possible future condition:Se eu tiver dinheiro, comprarei um carro.(If I have money [in the future], I will buy a car.)
- 1Incorrect usage of
tuandvósforms: In Brazilian Portuguese,tuandvósforms are less common in daily speech, often replaced byvocêandvocês. However, in European Portuguese,tuforms are standard. Be mindful of the regional context when conjugatingtiveresortiverdes.
Real Conversations
Far from being an overly formal or academic construction, the Future Subjunctive of ter is a cornerstone of natural Portuguese communication. It appears across all registers, from casual texts to professional emails, allowing speakers to manage expectations, propose plans, and discuss possibilities with appropriate nuance. Its ubiquity reflects the Portuguese language's emphasis on distinguishing between certainty and contingency, especially when projecting into the future.
1. Everyday Planning and Logistics (Informal):
In text messages or casual conversations, tiver is essential for making flexible plans.
- Oi! Se você tiver um tempinho depois, me avisa pra gente conversar. (Hi! If you have a little time later, let me know so we can chat.) – This is a common, polite way to suggest meeting without demanding immediate availability.
- A gente faz churrasco no sábado se tiver sol. (We'll have a barbecue on Saturday if it's sunny.) – The event is contingent on future weather.
2. Professional and Academic Contexts (Formal/Semi-Formal):
In work emails or meetings, tiver maintains professionalism by acknowledging variables and avoiding premature commitments.
- Prezado(a) [Nome], assim que tivermos os dados completos, enviaremos a análise final. (Dear [Name], as soon as we have the complete data, we will send the final analysis.) – Signals that the analysis is pending future data acquisition.
- Se o projeto tiver orçamento extra, poderemos contratar mais pessoal. (If the project has extra budget, we can hire more staff.) – Discussing future possibilities for resource allocation.
3. Social Media and Online Interactions:
Even in quick online posts or comments, the Future Subjunctive is used to express conditions.
- Posto a receita completa quando tiver 10k likes! (I'll post the full recipe when it gets 10k likes!) – A common influencer tactic, setting a future condition.
- Alguém sabe onde tem? Se tiver link, me mandem! (Does anyone know where it is? If there's a link, send it to me!) – A quick request on a forum.
4. Cultural Insight: Politeness and Indirection:
The frequent use of the Future Subjunctive can also be seen as a reflection of a cultural tendency towards politeness and indirectness in Portuguese-speaking societies. By saying Se você tiver tempo... instead of Se você tem tempo..., you subtly acknowledge that the other person's time is not guaranteed or at your disposal, offering a softer, more considerate approach to making requests or suggestions. It manages expectations by embedding uncertainty directly into the grammar, rather than asserting a factual (and potentially demanding) condition.
Quick FAQ
ter instead of tiver in these contexts?No. Using the infinitive ter where the Future Subjunctive tiver is required is a grammatical error for this irregular verb. Ter only functions as the Future Subjunctive for regular -er verbs. Always use tiver for the future subjunctive of 'to have'.
tiver?The core usage and meaning of tiver are consistent across Portuguese-speaking regions. The main difference lies in the frequency of the tu (tiveres) and vós (tiverdes) forms. European Portuguese uses tiveres regularly when addressing a single informal 'you', while Brazilian Portuguese largely opts for você tiver.
tiver always need a trigger word like se or quando?Almost always. The Future Subjunctive is typically dependent on a conjunction or adverb that introduces a conditional or temporal clause. While sometimes implied in very casual speech, explicitly including the trigger word ensures grammatical correctness and clarity.
tiver?Yes. The use of the Future Subjunctive doesn't necessarily reflect your personal certainty about an event, but rather the grammatical structure required for a contingent future clause. Even if you are personally confident, if the clause expresses a condition or a future time reference for 'having' something, tiver is the correct form.
It's called "Future" because the action or state of the subjunctive verb itself (in this case, 'having') is projected into the future, and its fulfillment is pending. The English translation using the present tense (if I have) is simply a common idiomatic shortcut in English that doesn't reflect the same grammatical nuance as Portuguese. In Portuguese, the form explicitly marks that the 'having' is a future possibility, not a present reality or an accomplished fact.
tiver relate to other verbs' Future Subjunctive forms?For most regular verbs ending in -ar and -er, their Future Subjunctive forms are identical to their infinitive forms (e.g., falar -> quando eu falar; comer -> quando eu comer). For regular -ir verbs, it's also based on the infinitive (e.g., partir -> quando eu partir). However, ter is one of a group of highly irregular verbs (like ser -> for, estar -> estiver, ir -> for, vir -> vier) that have unique and irregular Future Subjunctive stems. This makes tiver a special case.
ter considered formal?Not at all. It is standard, grammatically correct Portuguese used in all registers of speech and writing. Using tiver correctly makes your Portuguese sound natural and accurate, not overly formal. Avoiding it by using the indicative (se eu tenho) would be considered incorrect or highly informal in the wrong context.
