Translation:Do you want to dance this dance with me?
Because it's "tiun ĉi dancon". If you've already got one o-word as the object ("dancon"), it's a grammatical error to put another one in ("tion").
"Tio" is a general word for "that", whatever "that" might be, and "tio ĉi" is "this", again in a general sense.
"Tiu" means "that specific one (from a list of options)". So "tiu danco" is "that particular dance (from all the dances that we could have done)". And "tiu ĉi danco" is "this dance (that's just starting now, as opposed to any other that's happening this evening)".
Hope that helps!
That is so complicated !!! well for me as a french speaker .
I can barely make the difference between this and that in english . So I just learn the translation of each word in esperanto and english to do my exercices in Duolingo (Esperanto is not available from the french native language). I'm wandering how they translate this and that in the english (or french) course ...? celui-ci and celui-là ? practically no difference...
I thought Esperanto was supposed to be very easy . You will probably think that there is a good reason for this (that?) rule but in certains languages it's not at all !
The complication is not between "this" and "that". The word "ĉi" just adds the idea of "proximity", so "tio ĉi" is "this". It often doesn't actually matter whether you include "ĉi" or not, just as in French there's often very little difference between "ceci" and "celà".
What's different in Esperanto — where the words don't correspond to what you know from English or French — is the difference between "tiu" and "tio". You can use both of them with or without "ĉi", but "tio" is general whereas "tiu" is specific. (We don't have words in English and French that correspond exactly to "tiu" and "tio", so you have to learn how to use them in Esperanto).
"Tio timigas min!" = "That scares me!" (where "that" could be just about anything) [pointing with your finger] "Tiu timigas min!" = "THAT scares me!" (that one right there!) "Tiu ulo timigas min!" = "That guy scares me!" (must be "tiu" because it's a specific person)
Hope that helps. :)
Mi ne povas fari tion.
Tio - it can stand alone as a pronoun. (That is not a meal - Tio ne estas mangxon)
Tiu - it cannot stand alone, it works as an adjective (That water is black! - Tiu akvo estas ❤❤❤❤❤!)
And if you add Cxi you convert them to this.
This is not a meal - Cxi tio ne estas mangxon
This water is black! - Cxi tiu akvo estas ❤❤❤❤❤!
In your statement, Tio is refering to something previosly said in the context (an activity, meal, travel, etc), and that thing is object of the verb "fari". So it gets the n ending. If you want to use tiu you have to add the thing refered and the corresponding ending.
Mi ne povas fari (cxi) tiun vojxagxo - I cannot do (this)/that travel.
Hope this helps.
We need to be careful with what we mean by "specific thing." I'm not sure that expression means the same thing to all people in all contexts. "Rigardu al la mezo de la tablo? Kio estas tio sur la tablo?" is pretty specific, but it's correct to say "tio" there.
"I can't do that" would be "mi ne povas fari tion" in all the context that are springing to mind for me in the moment.
