Google Spell Checker

I can’t spell, never have been good at it. I put it down to be ever so slightly dyslexic. So basically when working on a computer I just type the way it sounds and the spell checker does the rest. However I have found Microsoft’s spell checker to be woefully inadequate at times. For example I was trying to type: deliberately obstreperous this morning but when I typed in my close approximation: derlibertatly obstrepidus, I had Mr Gates stumped!
So I always copy and paste into Google and sure enough it says, “Did you mean: deliberately obstreperous” and yes Google I did mean that, thank you!
