Portuguese Conditional Perfect: 'Would Have' (teria feito)
Grammar Rule in 30 Seconds
Use the Conditional Perfect to talk about hypothetical actions that didn't happen in the past.
- Use 'teria' + past participle for most verbs: 'Eu teria comido' (I would have eaten).
- Use 'haveria' only in very formal or literary contexts; 'teria' is standard.
- The past participle must agree with the subject if using 'ser' or 'estar' in passive constructions, but usually remains invariant with 'ter'.
Overview
Ever double-tapped a post on Instagram and instantly panicked? Or maybe you missed a flight and grumbled to your travel buddy, "We would have arrived on time if you hadn't forgotten your passport!" Welcome to the Portuguese Conditional Perfect, known formally as the Futuro do Pretérito Composto. This is the ultimate tense of alternative timelines, missed opportunities, and dramatic regrets.
If you want to talk about what would have happened in the past, but didn't, this is your golden ticket. It's the essential tool for Monday morning quarterbacks and chronic overthinkers alike. We use it constantly in daily life.
Whether you are arguing about a referee's terrible call in a football match, explaining to your boss why your zoom presentation failed, or just imagining a totally different life path, you need this grammar point. It adds a whole new layer of depth to your Portuguese vocabulary. Instead of just stating boring facts about what actually happened, you can finally talk about what could have been.
Grab your favorite cafézinho, sit back, and let's master the art of "woulda, coulda, shoulda" in Portuguese!
How This Grammar Works
ter (which means to have), push it into the conditional tense (teria), and attach the past participle of your main verb (comido, ido, dito). It is a compound tense, meaning it always takes two words working together to do the job of one concept. The truly beautiful part?ter, you basically know the entire tense! The second word, the participle, rarely ever changes. It doesn't care if you are a man, a woman, or a group of fifty people.se), creating a clear cause-and-effect relationship in the past.Formation Pattern
ter in the Conditional tense (Futuro do Pretérito).
Particípio Passado) of your main action verb.
ter:
teria (I would have)
terias (You would have - informal, mainly used in Portugal or parts of Brazil)
teria (He/She/You would have)
teríamos (We would have)
teriam (They/You all would have)
-ado (falar -> falado). For -ER and -IR verbs, drop the ending and add -ido (comer -> comido, partir -> partido).
Eu teria falado (I would have spoken). Nós teríamos comido (We would have eaten).
Fazer (to do/make) becomes feito. Dizer (to say) becomes dito. Escrever (to write) becomes escrito. Ver (to see) becomes visto. Vir (to come) becomes vindo. Abrir (to open) becomes aberto.
teria(s/mos/m) + Participle. Boom. You are now fluent in hypotheticals.
When To Use It
Eu teria estudado mais para aquela prova!).Se eu tivesse dinheiro, eu teria comprado aquele iPhone novo.).Nós teríamos ganhado o jogo se você tivesse passado a bola!).Eu teria chegado mais cedo, mas a ponte estava fechada.).Common Mistakes
ter, the participle NEVER changes. Do not say Ela teria ida! It is strictly Ela teria ido. The participle stays masculine singular, always, regardless of who is speaking.ter. While haver technically exists in Portuguese (haveria feito), it sounds incredibly archaic, like you are a time-traveling poet from the 1800s. Stick to ter for daily life.Eu teria fazido. Fazer is completely irregular. It must be Eu teria feito. Same with abrir (aberto, not abrido). Always double-check your irregulars before speaking.teria feito is the absolute standard for "would have done". But if you go to Lisbon, you will often hear people use the Imperfect tense (tinha feito) to mean the exact same thing! A Portuguese person might casually say "Eu tinha ido à festa, mas choveu" to mean "I would have gone to the party, but it rained." Context is key when traveling!Contrast With Similar Patterns
Simple: Eu faria (I would do). Focuses on a hypothetical present or future. "I would do it right now if I could."
Perfect: Eu teria feito (I would have done). Focuses strictly on a hypothetical past. "I would have done it yesterday, but I completely forgot."
Pretérito Mais-que-perfeito) vs. Conditional Perfect:Pluperfect: Eu tinha feito (I had done). This is an actual fact that happened before another past action. "By the time you arrived, I had already eaten."
Perfect: Eu teria feito (I would have done). This is fake news. It did not actually happen. "I would have eaten, but you took my food."
tinha) is reality. The Conditional Perfect (teria) is pure imagination. (Except in Portugal slang, as mentioned earlier, where lines blur!).Quick FAQ
Do I always need to use the word "Se" (If) with this tense?
Not at all! You can use it totally on its own. Like replying to a friend: "I wouldn't have done that." (Eu não teria feito isso.). No "if" clause is required to make sense.
Can I use this in text messages or is it too formal?
It is extremely common in casual texting! Brazilians abbreviate it all the time. "Eu teria ido fds" means "I would have gone this weekend."
What happens with reflexive verbs? Where does the tiny pronoun go?
In Brazil, the pronoun usually goes right before the auxiliary verb ter. Right: Eu me teria lembrado. Wrong: Eu teria lembrado-me. In formal European Portuguese, it splits the auxiliary: ter-me-ia lembrado.
Is this tense hard to learn?
Nope! Once you nail the 5 forms of teria, it is just plugging in words you already know. You've got this entirely under control!
