Irregular Future: Fazer (To do -> I will do)
fazer is irregular in the future tense, changing its stem to far- before adding standard endings (farei, farás, fará).
Grammar Rule in 30 Seconds
The verb 'fazer' (to do/make) changes its stem to 'far-' in the future tense instead of using the infinitive.
- Drop the '-zer' from 'fazer' and add the stem 'far-'.
- Add the standard future endings: -ei, -ás, -á, -emos, -eis, -ão.
- The first person singular is 'farei', not 'fazerei'.
Overview
Mastering the future tense of the Portuguese verb fazer (to do, to make) is a crucial step for intermediate learners aiming for fluency and comprehensive understanding. While its present and past forms are frequently used, its future manifestation often presents a challenge due to its inherent irregularity. Unlike most Portuguese verbs that form their simple future by adding specific endings directly to the infinitive, fazer undergoes a significant stem change, transforming from fazer to far- before accepting the standard future suffixes.
This irregularity is not an arbitrary quirk but rather a linguistic inheritance, reflecting centuries of phonetic evolution from its Latin roots. Recognizing and correctly employing farei, farás, fará, faremos, fareis, and farão distinguishes a learner from a proficient speaker, enabling deeper engagement with formal texts, nuanced communication, and a richer appreciation of the language's structure. Understanding the "why" behind this change helps cement the "how," providing a more robust grasp of Portuguese verb morphology.

How This Grammar Works
fazer in the simple future tense stems from its historical development from Latin. The Latin verb facere (to do, to make) evolved into Old Portuguese fazer. When forming the future tense in Latin, the infinitive was often combined with forms of habere (to have), which eventually fused into the synthetic future endings.fazer, the original stem was essentially shortened, and the final e of the stem dropped, allowing the future tense suffix, which historically included an r, to attach directly to the shortened form. This process effectively yielded fa- plus the r from the future suffix, resulting in far-.far- instead of fazer- before the endings. The standard simple future endings in Portuguese (e.g., -ei, -ás, -á) are consistent across all verbs, both regular and irregular. The key distinction for fazer, as well as dizer and trazer, is that their infinitive stem itself modifies before these regular endings are applied.farei, the stress is on the ei, and in fará, it's on the á. This consistent stress pattern is crucial for correct pronunciation and comprehension, as it often differentiates simple future forms from other verb tenses or even other words.Ela fará a apresentação amanhã (She will do the presentation tomorrow) highlights the far- stem and the stressed á ending. This structure clearly expresses a future action that is typically more formal or definite than its periphrastic counterpart. Similarly, Nós faremos o possível para ajudar (We will do our best to help) demonstrates a commitment or strong intention using the irregular future, maintaining the stressed ending on faremos.Formation Pattern
fazer follows a precise, albeit exceptional, pattern. The key is to internalize the unique stem change before applying the regular future endings. This is not about memorizing each conjugated form individually, but rather understanding the single stem transformation and the consistent set of suffixes.
fazer:
fazer.
fazer, you completely bypass the original infinitive stem fazer-. Instead, the irregular future stem is far-. This is the crucial step; do not try to derive far- by removing parts of fazer as you would with a regular verb. Simply know that fazer transforms into far- for its simple future forms. This unique stem is far-.
far-, you append the regular future endings that are consistent across all verbs in this tense. These endings always attach to the stem and determine the subject pronoun:
Eu (I): -ei
Tu (You, informal): -ás
Ele/Ela/Você (He/She/You): -á
Nós (We): -emos
Vós (You all, formal/archaic): -eis
Eles/Elas/Vocês (They/You all): -ão
Eu: far- + -ei = farei. Example: Eu farei a reserva esta noite. (I will make the reservation tonight.)
Eles: far- + -ão = farão. Example: Eles farão um ótimo trabalho. (They will do a great job.)
fazer by attaching endings directly to fazer-, which would incorrectly yield forms like fazerei. Always remember the distinct far- stem for the simple future.
When To Use It
ir + infinitive, e.g., vou fazer) dominates casual spoken Brazilian Portuguese, the simple future of fazer (farei, etc.) remains indispensable for specific registers, nuances, and contexts. Its usage often signals formality, certainty, or a literary flair, making it vital for comprehensive language proficiency. You’ll find it prominent in situations demanding precision and a more elevated tone.- Formal Writing and Speech: The simple future is the preferred tense in official documents, academic papers, legal texts, formal emails, public speeches, and professional correspondence. It lends an air of seriousness and authority. For instance, in a business context,
Nós faremos o pagamento até a data limite.(We will make the payment by the deadline.) sounds more professional and committed thanNós vamos fazer o pagamento.... Similarly, a politician might declare,Faremos todo o necessário para o progresso do país.(We will do everything necessary for the country's progress.)
- Predictions and Certainty: Use the simple future to express predictions about the future that carry a higher degree of certainty or conviction from the speaker. It suggests a more definitive outcome than the
ir + infinitiveconstruction, which can sometimes imply immediate plans or general intentions.O relatório fará uma análise aprofundada dos dados.(The report will make an in-depth analysis of the data.) – this implies a guaranteed characteristic of the report.
- Fixed Expressions and Impersonal Constructions: Certain common phrases, especially those related to weather or time, frequently employ the simple future. These often use
fazerimpersonally in the third person singular (fará). For example,Amanhã fará sol.(Tomorrow it will be sunny.) orNo inverno fará muito frio.(In winter it will be very cold.) You’ll also hear it in expressions likeIsso fará sentido mais tarde.(That will make sense later.)
- Literary Contexts and Journalism: Due to its conciseness and formal register, the simple future is ubiquitous in literature, poetry, and journalistic reporting. News headlines and articles often favor it to convey future events efficiently. For example, a newspaper headline might read,
Presidente fará visita oficial à Europa.(President will make an official visit to Europe.) Authors use it to create a sense of narrative flow and to describe future actions or states with a sense of classical elegance.O herói fará a escolha que o destino lhe impôs.(The hero will make the choice destiny imposed upon him.)
- Concessive/Hypothetical Contexts (Less Common): In highly formal or archaic language, the simple future can sometimes appear in concessive clauses, implying a possibility or concession, often translatable as
