I wonder what language that might be..
Yet another Esperantido, presumably, that "fixes" things that somehow, all the other ones have missed.
When do you put ĉu by itself without ne at the end after a comma? Seems like I saw that but I have no idea where.
When the main verb is negative, I think it sounds better not to have "ne" in the tag question - as in English.
Kaj lia nomo estas Zamenhofo!
