O Futuro do presente ( Indicativo )
I've noted that several people are having a hard time grasping this tense.
Here's my attempt to elucidate:
"Eles terão pensado na partida."
Translation:They will have thought about the match.
To understand the present future tense you gotta understand that there's two types, Simple and compound:
Simple: A fact that will probably happen in the future.
"Ele estudará amanhã" ( He will study tomorrow )
"Ele jogará a partida amanhã" (He will play the match tomorrow )
Compound: A fact that will happen in the future but that will end before another future fact.
"Antes do sinal bater, os alunos já terão terminado o teste." (Before the bell rings, the students will have ended their test".
"Antes do fim da copa, os jogadores terão pensado no resultado da partida." (Before the end of the cup, the players will have thought about the match result)
It's the same for Simple past tense:
Simple: A fact that started in the past and is finished.
"Ele estudou ontem." (He studied yesterday)
"Eles pensaram sobre os jogos ontem" (They thought about the games yesterday)
Compost: A fact started in the past but that can extend until the present.
"Eu tenho estudado muito para os exames." (I've been studying for the exams.)
"Eles tem pesando sobre os jogos passados" (They have been thinking about the past games)
Somene in this question posted:
[Does this mean "They must have been thinking about the match"? or "They were probably thinking about the match?" or "I bet they were thinking about the match?"]
But here's why not:
"They must have been thinking about the match" = "Eles deviam estar pensando sobre a partida" (this is a compound simple-past tense, "deviam")
"They were probably thinking about the match" = "Eles provavelmente estavam pensando sobre o jogo" (also, simple past, "estavam").
"I bet they were thinking about the match" = "Eu aposto que eles estavam pensando sobre o jogo" (also simple past, "estavam", and "aposto" is on present.)
As you can see, both past and future tenses in compound form need something beside itself to happen, and I think that's why people are struggling since Duolingo doesn't give more context.
Hope this can help anyone.
Feel free to comment if you have a better example or mine are wrong. :)
The people are having trouble doing what? Ans: grasping the tense. I interpret "grasping" as a gerund functioning like an object. However, this is an area in grammar where there is debate as to whether some "...ing" words are gerunds or participles - one such debate took place in the NY Times' grammar column written by the late Willliam Safire. Anyway, I see it as a gerund.
I asked my question because in Spanish you can use the future and conditional to suggest certainty or probablility in present time, as in the English: "Where is she?" "Right now she will have finished teaching and will be at home." [I am sure] Or "Where do you suppose she is?" "Well, normally she would have finished teaching by now and would be at home." [But can't say for sure.]
