The future perfect tense (Futuro Composto do Indicativo)
When you want to talk about an action that will be completely finished before a certain deadline in the future, you use the future perfect tense. In English, this is the equivalent of saying "will have done" or "will have finished".
To form the futuro composto, combine the future tense of the auxiliary verb ter (or occasionally haver) with the past participle of your main verb.
| Pronoun | ter (future) | Past Participle |
|---|---|---|
| eu | terei | projetado / recebido |
| tu | terás | projetado / recebido |
| ele/ela/você | terá | projetado / recebido |
| nós | teremos | projetado / recebido |
| eles/elas/vocês | terão | projetado / recebido |
Note: Regular past participles end in *-ado for -ar verbs, and -ido for -er and -ir verbs. When used with "ter" or "haver", the past participle never changes its ending to match gender or number.*
Actions completed by a future deadline
The future perfect is almost always paired with a time expression—such as até dezembro (by December), daqui a dez anos (in ten years), or até amanhã (by tomorrow)—to set the specific future timeframe.
| Ten years from now, the metropolis will have changed a lot. | Daqui a dez anos, a metrópole terá mudado muito. |
| They will have designed the new skyscraper by December. | Eles terão projetado o novo arranha-céus até dezembro. |
| Since pollution is increasing, we will have implemented renewable energy. | Visto que a poluição aumenta, teremos implementado energia renovável. |
| A year from now, this skyscraper will have received renewable energy. | Daqui a um ano, este arranha-céus terá recebido energia renovável. |
Just as in English, you can also use this tense to ask questions about what will have been achieved by a certain date:
| Will the government have implemented the underground transport by tomorrow? | O governo terá implementado o transporte subterrâneo até amanhã? |
