"I go to bed at eleven."

Translation: Vado a letto alle undici.

[shaunalouise]

Why not 'al letto'?

[jgbachand]

idiomatic?

[MagnesiumSodium]

why is it "alle undici" not "a undici"?

[allangottlieb]

What is wrong with "alle ventitre'". I would guess the 11 is pm.

[mmseiple]

I just added this to the system, but you need an accent mark: ventitré.

[Bill98991]

ventitré was not accepted 20 ottobre 2018

[AndesSky]

Thanks. Vado a letto alle ventitré, with the accent mark, still not accepted in Apr-2019.

[mmseiple]

Oops, I had added it, but just to the version with "io" at the beginning. It should be accepted for both now.

[Ariaflame]

And I'm fairly sure we were told that Italians tend to use a 24 hour clock.

[tuna0tseb]

Nowadays, sometimes, we use the 12 hour clock too. I think duolingo tells that to say ventitrè anziché (sorry, idk how to translate) undici is wrong, because it'basically wrong: you cannot say OH, ELEVEN IS THE SAME AS TWENTYTHREE, BC I'M ME AND EVERYTHING I SAY IS RIGHT .
Understood?

[greg1881]

why is it "alle undici" and not "agli undici"

[mukkapazza]

Telling time is done in the feminine. Che ore sono? È l'una. È la mezza. Sono le tre e un quarto. Ci troviamo alle ventuno. Tempo is masculine, but ora is feminine. Hope that helps :)

[CicelydAut]

Another voice for twenty three instead of eleven. We have been using a 24 hour clock, so this sentence says the writer goes to bed at 11am. More editing, please.

[sesundbackl]

Perché " Io vado a letto alle undici>" non è giusto?

[RonMoore12]

Both answers 1 and 3 are correct as above....aren't they?

[rjjacob]

Italian prepositions are driving me nuts!

[manaf34711]

Why can you not say "all'undici"

[mmseiple]

You don’t shorten “le” in front of a vowel, so you also can’t contract “alle.” It’s an articulated preposition (preposition + article, in this case a + le), so it follows the rules for the article. So:

l’una (because it’s “la,” singular to go with “una”) / all’una

Le undici / alle undici

[Tomas258654]

I go to bed at the eleven. Al vs. Alle?

[Dan878472]

hours are feminine

[john631799]

Bad bad drop down suggestions. Exact same alle a choices. What's the rule here?

[anna684111]

The dictionary says 'to go to bed' is 'andare a letto' but 'ando a letto alle undici' wasn't accepted. Why not?

[Dan878472]

Ando is not a word. Andò means he/she went in the Passato remoto. I think you want Vado a letto
