To begin a yes or no question. Ĉu vi parolas Esperanton?

May 28, 2015


wow it's just like Czy

May 15, 2016


And it is a mix of czech and... and... Uhhh, I don't know.

Thanks for explanation

March 30, 2016


is the sentence "Cu Esperanton parolas vi" correct?

November 27, 2016


There's nothing ungrammatical about it. It's technically correct although people wouldn't normally use that sentence order. It's fine though. :)

November 27, 2016



November 27, 2016


Esperanto doesn't have a word order, and i love this.

November 4, 2017


Thank you so much!

June 8, 2018


Doctor Zamenhof was inspired by his (native?) Polish czy when creating this word. It is also a question particle.

May 29, 2015


In Ukrainian there is a similar particle.

June 17, 2015


Ukranian and polish have simular words and grammar

December 13, 2015


They're both Slavic, like Russian.

January 27, 2016


except russian and ukrainian are both in a different category of slavic languages

May 15, 2016


I'm pretty sure they're both Eastern Slavic languages.

May 27, 2016


If I recall correctly Polish (and Czech) descend from the East Slavic family while Russian and Ukrainian are West Slavic descendants

This word is EXTREMELY unclear as a translation task alone. It could translate to almost any word depending on what you're then going to ask : / If you want to make us translate "really?" then why not put "ĉu vere?"

May 28, 2015


I actually wrote "cxu vere" the first time and it came back as wrong. I agree that the sentence should be changed.

May 28, 2015


This task is unclear. I'm a low-intermediate student who's been learning Esperanto for over a year and I couldn't get this right. It's just not clear what the answer is supposed to be; I think there must be a better way to present this word.

May 28, 2015


Under tips and notes it had phrases with ĉu and one was "ĉu?" meaning "Really".

May 29, 2015


"ĉu" alone is not the short form of "ĉu vere?" (really), but the unpolite form of "Pardonu, kion vi diris?" (Pardon, what did you say?)

"ĉu" is also a conjunction meaning "whether"

September 21, 2015


Well, this word is really a little bit hard to translate. The same would happen if one tries to translate the auxiliary verb "do" in English. In my opinion we could think that, isolated, as a question, it simply denotes surprise.

May 29, 2015


I answered "Does it?" Should it be an acceptable answer?

May 28, 2015


I'm not fluent in esperanto (I just started learning 60 minutes ago) but I think that would be "Ĉu ne?"

May 29, 2015


I thought "Ĉu ne?" meant "Isn't it?" and "Ĉu?" meant "Really?", but I see your way of thinking. In a question it seems to mean "Is this true?" at the beginning of a statement that you can answer yes or no to. I think it is kind of similar to the French question beginning "Est-ce que ..." which cannot be literally translated to English ("Is it that..."), but gives the same feeling. ("He plays." becomes "Does he play?" We could say "Is it true that he plays?" or "Does he really play?") See the tips and notes for this lesson and scroll all the way down: https://www.duolingo.com/skill/eo/Basics-2

May 29, 2015


That's a lot of languages you're learning...

June 1, 2015


That's a lot of languages Duolingo offers to learn. I spend an enormous amount of time, more on some than on others. Of course, it makes perfect sense to learn Esperanto, as it will be impossible to learn every language there is. Sign Language and Braille are the other two essential languages, as I cannot expect a deaf person to listen to me speak or blind person to write to me in English.

June 1, 2015


<- is deaf

Just a friendly reminder to everyone out there that there are many different sign languages, just as spoken! ^^ (Because I find that people are surprisingly ignorant of that...)

June 9, 2015


I just started learning Esperanto but seems to me the literal translation for Cu ne would be "Is it no?".

June 1, 2015



"Ne" means "not" as well as "no" http://esperanto-panorama.net/vortaro/eoen.htm http://www.gutenberg.org/files/16967/16967-h/16967-h.htm#letterC

"Ĉu ne" means "Is it not?" or "Isn't it?" which is simply a contracted form of the same thing.

This expression doesn't really translate word for word. We replace their expression with one of ours. We could say "He plays, is it not so?" or "He plays, doesn't he?" or "He plays, or not?"

June 1, 2015


Ah that makes more sense.

June 1, 2015


No; right before you click "begin," one of the bullet points translates that phrase as "Ĉu ne?" A better translation would be closer to "Doesn't it?"

May 29, 2015


I think this is similar to "acha(s) " in portuguese or "you think..." in english. In portuguese, using this word is kinda optional but it lets the other person know that a question id coming and a feedback is expected. In portuguese, not using a word like this still makes sense but in esperanto things dont seem to "flow" right without it.

Having said, I think thus exercice is not not only wrong but it is also not very friendly for begginers. The next exercice clarifies more the use for this word.

June 22, 2016


In my understanding, "Ĉu" is used at the start of yes/no questions, such as "Ĉu vi volas danci?". I've never seen it being used as to mean "really".

May 30, 2015


Does everything I write have to be in the standard global acrolect when it is a conversational word? I translated it as "eh?"

May 29, 2015


"eh?" is used differently then "Is it so?" or "Really?"

May 29, 2015


How is it used differently apart from being prepositional rather than postpositional?

May 29, 2015


"Eh?" in the US is more like "What did you say?", "Excuse me, could you repeat that?" or "Huh?", "I didn't get that. What?"

"Is it so?" or "Really?" is more like "I heard you, but I am not sure that I believe you.", "You have got to be pulling my leg.", "Are you sure you're not just trying to pull one over on me?", "Are you just kidding?" although it could be "I don't think so. Are you sure?"

Unless you are Canadian, in which case you might just use it for this also. Even then, it is different as it is used for both "Isn't it?" and "Is it so?" It is also used here and there just to see if people are paying attention, as in "Did you get that?", "Did you hear me?", "Are you even still listening to what I am telling you?" You yourself called it a conversational word making me immediately think of this last Canadian use, which is not the same as "Really?" or "Is it so?" : "I was going to the store, eh, when a big truck crashed into the gas station, eh and you should have seen......" Here it is used more like "This is exactly what happened. There is no doubt, but are you listening? Wait until you hear what happened next?"

"Isn't it?" is more like "I thought it was so. Am I wrong?" or "This is the way it is, but perhaps that is not true?"

"It's nice here, eh?" but is it used this way by itself? We would certainly assume the first meaning when it is by itself.


May 29, 2015


I went with 'Is it true?' - which is correct in most contexts.

May 29, 2015


The Jamaican pronunciation of 'true' is 'chu' because tr slurs into ch. But even they would say 'fi chu' what they write as 'for true' or 'a chu' meaning 'is it true'. Its intresting how. Esperanto has so many similarities with creoles, except for being easy to pronounce, and compensating grammatical simplification by being rich in modalities.

May 29, 2015


This word was actually inspired by Polish "Co nie?" (Ĉu ne?), which means something like "Isn't it?".

May 31, 2015


Ĉu might be the only word I know which is shorter than it's English equivalent:)

May 29, 2015


Some people told me that only need 3 months that you can know how to speak Esperanto, Is it true? And so, I'm so excited to learn Esperanto but I only can use Duolingo because I like the way how I can learn languages. Saluton! :D

May 30, 2015


Ĉu estas pli ĝuste tradukita kiel "whether" kion estas "really". Ekzemple ĉu la vetero estas malbona? La alternativo "really" ne funkcias preskaŭ tiel. Ekzemple "vere la vetero estas malbona?"

June 1, 2015


How am I to know what this new word is? Am I missing somewhere on the website?

June 29, 2015


So is it like the Polish " Czy" ?

November 11, 2015


it's kind of like "choo choo train" noises

December 26, 2015


Ah, so it's much like lojban "xu" (is it true that...)

April 2, 2016


How do I type the accent over the c?

November 15, 2017


I cant write that thing on the c

November 20, 2017


I answered, "right," and was marked as incorrect, even though "right?" is a choice.

May 28, 2015


I think that is because it is a stand alone word here. "He plays, right?" could work, but "Right?" is certainly not used much whereas "Really?" works better alone. Like a dictionary, we need to pick the best definition for the situation or sentence. Not all definitions apply to all sentences.

May 29, 2015


I agree. That's why "right" is an acceptable choice for this word, according to the Duolingo definition (when you mouse over the word). Point is, I wrote, "right," and was buzzed wrong.

May 29, 2015


So, you use "Right?" all by itself? I would definitely not, but I would use it at the end of a question. You could try reporting it and see whether Duolingo will add it as an alternative, or not. I personally think it can be used for this word when not used alone, which is why it is listed.

May 29, 2015


Really? Because "whether" or "if", which is how I learned this word really doesn't fit well in a one word sentence.

May 28, 2015


They do state this at the very end of the "tips and notes" in the beginning of this chapter; otherwise I probably would have gotten it wrong as well

May 28, 2015


"if" is listed as "se"

"whether" does list as "Ĉu"

http://www.gutenberg.org/files/16967/16967-h/16967-h.htm (English to Esperanto)

However in this dictionary, which goes from Esperanto to English, more meanings are listed: http://esperanto-panorama.net/vortaro/eoen.htm

"ĉu" is listed as "either", "if", "is it", "whether"

I think an alternate for the stand alone which Duolingo has as "Really?" could be "Is it so?"

May 29, 2015


I have answered "Do?" and it was not accepted as a valid one.

May 31, 2015


I suppose that in a question, ĉu is the equivalent of the french est-ce que, except in that particular sentence there.

June 6, 2015


This question should be removed.

July 17, 2015


Would this be the equivalent of 'do/does/is' in English or 'est-ce que (c'est)' en français?

September 6, 2015


Would an interpretation of
Esperanto "Ĉu?"
English "What?"
(as in the "Can't hear you, say it again! [all politeness polished off]"-variant, and somewhat similar to "Huh?")
be farfetched?

December 14, 2015


Oni povas respondi al ĉua demando nur per aŭ jesa aŭ nesa respondo. Eble la demand-vorto pli taŭga en tia situacio estus: kio? kun demandema intonacio.

December 14, 2015


I actually wrote"isn't it" and it was not correct but I was sure about being correct.why Cu has dual meaning as isn't it or do and really?

January 13, 2016


"Ĉu" is word which makes thing interrogative. 'It is a book' - 'Gxis estas libro', 'Is it a book?'-"Ĉu ĝi estas libro?", By alone 'Ĉu' is itself a question 'weather it's real or not'? 'really' is not exact translation but equivalent or approximate. Real translation for 'really' in Esperanto is 'Vere'.

'Ĉu' may seem odd but such words are exists in other languages. For example, in Hindi word 'kyaa' works exactly like 'Ĉu' .

'Yes kitab hai' - 'Ĝis estas libro', 'Kyaa yeh kitab hai?'-"Ĉu ĝi estas libro?"
Ĉu? - Kyaa? (Kyaa, sach me?) = really?

January 14, 2016


Thanks buddy

January 21, 2016


I always thought that Cu meant something more along the lines of seriously? And not really. Because I was under the impression that Cu could only be used in the context of being surprised, but I'm obviously wrong. Is there another really or something?

January 25, 2016


Ĉu is a question participle. Literally it means "whether", so in this context it means "really", as you could take it as a "please reaffirm whatever you just said" or "could you explain more about that?" if used alone. It's definitely a nuanced word.

"Vere" (literally "truly" from vero, "truth") is used often to mean "really". There's also "reale" (literally "really" from realo, "reality"). These are often interchanged, with "vere" being more common due to its shorter pronunciation, but I feel like there are some situations where you should use one over the other.

A) Mi havas dek katojn. - I have ten cats.

B) Ĉu?! - Really?!, Are you kidding?!

A) Mi ricevis malbonan noton. - I got(received) a bad grade.

B) Vere? - Really?, Truly?, Are you speaking the truth?

A) Estas monstro sub mia lito. - There's a monster under my bed.

B) Reale? - Really?, In reality?

My keyboard doesnt have that letter

December 14, 2016


Mine neither. Idk how to type it correctly

October 2, 2017



February 11, 2017


Like a bad word in my language :0 ;D

March 16, 2017


I think "isn't it?" could also be a correct translation

June 7, 2017


This remembered a dirty word in Portuguese (c) that means "butth**"

July 27, 2017


I just started learning Esperanto like 10 mns ago.

November 13, 2017


Really? is the correct answer, cause if you see the prounouce (plus sorry for my grammar :c) that with cap letter at beginning (example: Then), then its the right answer. Its easily to cheating (for me thought) except if there is two with cap letter. Hope its help for beginners.

December 22, 2017


Which language keyboard do you use for esperanto letters?

January 17, 2018


INTL keyboard allows you to type them

April 8, 2018


I cant wait to use this

February 7, 2018



March 1, 2018


Could this also mean "Oh?"?

March 18, 2018


I dont have such an accent on my keyboard :(

March 20, 2018


I've always interpreted Cxu as a word representing a binary query with implied options. So the way I've been think of this is "Is that so?" It implied that the query implied to the previous statement. The thing that confuses me though is when the course says "Ĉu la bebo estas knabo aŭ knabino?" Following what I thought was the definition, the answer to this question should simply always be "Jes." since the baby IS a boy or a girl. That would be an abridged for of "Is it a boy or a girl?" then "Yes, it is a boy or a girl."

October 14, 2018



May 2, 2019


Sounds like Populous 3.

June 20, 2016


i have completed basics 1 and 2 and then started the skill strengthening exercise. Not sure how I am meant to know that cxu in this context means really? when i have only been taught it as meaning is

July 9, 2016


Really was the only option that had a capital letter like Cxu

September 25, 2016


It is a great work, very useful.

October 28, 2016


Isn't cû for questions?

October 29, 2016



February 17, 2017


lol I thought it meant pikachu
