Both of these correct options this gives are incredibly awkward in English
Agreed. This was just awkward and redundant.
Why have "although" and "however" in the same sentence?!
Kial oni bezonas "tamen" en tiu ĉi frazo?
Non sequitur of the year.
"Though she does not speak Japanese, she speaks Chinese" should be accepted. Either "although" or "though" can be used at the beginning of a sentence.
This is the first phrase I had to skip. I had no idea what was trying to be said, talking way too fast for me.
Agree with all the above comments
Could you have put the tamen before the ŝi?
