"The musician plays music."
Translation:La muzikisto ludas muzikon.
"La muzikisto muzikas muzikon" should be accepted. The use of the verb "ludas" clearly follows an English convention, it should not be imposed in esperanto which is supposed to be a universal language. In most languages "to play an instrument" and "to play" are two very different verbs. I cannot imagine myself saying "I'm playing the violin" in Spanish, it would give the impression that I'm pretending that the violin is a toy and maybe I'm pretending that it is a Klingon starship.
Well, Zamenhof was free to grab bits from any language he wanted. And, if this is truly an English-only feature...then it's an English-only feature that the language's developer was comfortable using. And Zamenhof did use ludi in the sense of playing a musical instrument.
“la fratino Anna Kirillovna alveturis al mi kun sia edzo; Ivan Kirilloviĉ tre dikiĝis kaj ĉiam ludas violonon...”
I checked on the interwebs and it seems that "ludas" has the same two meanings in Esperanto as in english (which is something I find quite annoying tbh)
"La muzikista muzikas" should be accepted too (which it isn't yet). I reported it and hopefully this (and other options?) will be added too.
