Autumn. You mean autumn.

"Fall" sounds ambiguous. I think "Autumn" is better in this case

I think u mean autumn

Perhaps autumn and fall could be acceptable

Fall is American only Australians and English people call it autumn

Of course there is American English. I am from the UK but see no issue with calling autumn 'fall' as 330 milllion people are already doing so and should be free to do so. This app is not about trying to retrain native speakers to suit the prejudices of other learners.

Both autumn and fall are the correct english in both britain and america/canada, both originated in england and were used there aswell, just autumn took over fall in britain in 18th century for some reason... feel free to use either one

Why is it "the fall"?
