Since "bonus" = "would be good", could "would be happy" also be phrased as "felicxus"?
Yes, I would think so.
Yes! I put that, and it worked. :)
Also, "moknomo" can mean nickname.
Really? I know kromnomo does, but I haven't heard of "moknomo".
Yes, according to the Esperanto Dictionary by J.C. Wells, nickname is "moknomo" or "ŝercnomo."
Alright, I'll take your word for it.
"Se mi havus kaŝnomon, mi estus ĝoja!" is wrong?
joyful and happy aren't quite the same things.
