It would be nice if there is no need for spelling.
Consider word like:
STOP
The one everyone understands all around the world.
And then consider:
EWE
Female sheep, go figure?
Silent letters, if they are not pronounced why do we need them?
KNIGHT
KNIFE
Do we need double letters,
And then "C" "K" "CC" and so on...
I am happy my name BOB I can spell even backwards
cheers
