It would be nice to have somewhere a list of which synonyms (e.g. for "amazing") are accepted by Duolingo, since being told "wonderful" is wrong (when that's the most common translation most of my Arab friends use) is irritating.
You may suggest that it may be accepted
Autumn is wonderful in Paris or Autumn in Paris is amazing (if Duo wont accept wonderful) but please not the current Duo translation
Spring is better in Paris.
Apparently autumn is not accepted but fall is
Report it. The more of us who do, the more likely it is that Duo will take notice.
"The fall is amazing at Paris" should also be accepted
Caught out again by not being American, did not recognise out of any context that fall could ve a noun, please add autumn to the list DL
