The fact that Google doesn't recognize debatably as a word is, to put it simply, outrageous. Not to mention many other online services, such as Discord, don't recognize it, and just want you to put debatable instead. Debatable is an ADJECTIVE! IT ISN'T EVEN THE SAME TYPE OF WORD. I was so unbelievably and through roughly peeved when I found this out. I've played debatably in Scrabble before, and you know what, IT WAS LEGAL BECAUSE DEBATABLY IS IN THE SCRABBLE DICTIONARY!

SCRABBLE, A BOARD GAME, HAS A MORE DIVERSE DICTIONARY THAN GOOGLE.COM, THE MASSIVE CORPORATION WITH BILLIONS OF DOLLARS THAT IS CONSTANTLY UPDATING IT'S SERVICES, YET IT STILL CAN'T ADD DEBATABLY! 

This is atrocious on Google's part and to be completely honest I don't know what other good, common words could be left out of Google's dictionary, but I do know this, if we allow words like debatably to be ignored by Google, I would be really upset, so please sign this petition so GOOGLE can fix their god forsaken dictionary!
