Raised flower boarders ? Borders. The ariel power of the defender ? Aerial Defiantly not. Definitely These are not spelling mistakes. Just the use of similar sounding words. Any more please.
I use a Mac and recently upgraded my operating system to Mavericks (it was free, and I did it accidentally) it now has a similar spell check system to the iPhone which guesses the word for you.! all the examples you give above are included and I can understand why they pop up as spelling mistakes for anyone using the same system. Its bloody infuriating sometimes.
