"Θα έχω πει την αλήθεια."

Translation: I will have told the truth.

[Glossmad]

I was marked wrong for 'I will have spoken the truth'. Pretty much the same thing.

[Dimitra956826]

I just added this one, thank you ^.^

[BenjaminDe540650]

Is there another, more correct way to say the "spoken" sentence vs the "told" sentence? Μίλησε vs πει?

[jaye16]

If you used "speak" it would change the meaning. Here we are referring to imparting information...." telling something"

[Nicole966706]

Why « I will have told the truth» instead of « I shall have told the truth»?

[jaye16]

"I shall have told the truth." is an accepted translation and should have been accepted. If it wasn't it might be due to a technical problem please report that directly here:

I shall have told / I will have told?

[Vemund63]

These sentences are weird. "Will have told" - ? I can understand "would have told", but "will have told" -. I cannot make such sentences in norwegian.

[jaye16]

I can understand that. This is not a very common tense. the Future Perfect describes something that will happen in the future and will have finished by a certain time/date.

For example...."By the time my mother gets home, I will have finished all my lessons."
