H.W. Fowler wrote, "Fall is better on the merits than autumn, in every way: it is short, Saxon (like the other three season names), picturesque; it reveals its derivation to every one who uses it, not to the scholar only, like autumn."
"Fall" and "Autumn" were used at the same time both in the UK and USA at one point and it's just an accident that one chose one and not the other. Let's not ... Fall ... out over it.
i mean seriously, are we fighting over a fucking word. sure the majority of America says fall, and the majority of everything else says autumn. but you know what, i don't give a shit. i will sit here and say fall until /i/ fall. fuck you judgmental person. fuck you.
