"Is that true?"

Translation: Ĉu tio estas vera?

[SciuroRato]

Is it also acceptable to say 'Ĉu tio estas verE'?

[Rae.F]

That's basically saying "Is that truly?"

[Jaerivus]

Do esperantists not say "Ĉu estas vera?"

I thought I'd seen or heard that omission of the "tio," but I could be mistaken all around.

[salivanto]

No. I think "vere" here is explained elsewhere in the thread.

[Ael-wen]

I was wondering about that too. But in the tips of previous lessons, it is explained that "estas" alone can also be used to state the existence of someone or something, like in "Estas viro en la parko". I guess we need a nouns after "estas" and not simply an adjective?

[DavidLamb53073]

They do say, "Ĉu vere?" to mean "Really?"

[randypg]

Perhaps " Ĉu tio estas la vero ?

[Rae.F]

That's "Is that the truth?"

[randypg]

And please tell me the difference in meaning . Is that true ? It that the truth ?

[Rae.F]

There is not much difference in meaning, but Duolingo prefers strict translations because the focus is on understanding how the grammar works.

• "Is that true?/Ĉu tio estas vera?" true/vera is an adjective
• "Is that the truth?/Ĉu tio estas la vero?" the truth/la vero is a noun phrase

[squelettus]

What's the difference between tiu and tio? Is tiu used when pointing something, like closer to this than that?

[vikungen]

Basically:

If you use tiu by itself it will be understood as referring to a person:

Tiu portas ruĝan ĉemizon = that one wears a red shirt

if you're talking about a thing, you use tio:

Tio estas bona.

If you're being specific like saying that stone (that + stone) then you use also use tiu:

Tiu ŝtono estas peza.

Never two O's after each other, so don't say: Tio ŝtono

In all simplicity use tio on it's own and tiu with a noun.

Why veras and not vera?

[BioJess]

Veras = to be true (verb + adjective); vera = true (adjective)

[Soulfire86]

Could "Ĉu ne?" not be an acceptable translation here?

[servigo]

can translation cxu vere be used? it is not word by word but i've already heard it

[smile.and.the]

Is there a particular reason it can't be Kion veras?

[Rae.F]

"kio" is the correlative "what", not the demonstrative "that".
"kion" is in the accusative, but this needs to be in the nominative.
You need the "ĉu" to make it a question.

Why not tion?

[Rae.F]

Because it's the subject of the sentence, not the direct object of a transitive verb.

[Hendrik_olin]

could tio be interchanged with gxi?
