I can't see what all the confusion is about. You Americans can't spell, and you use incorrect terms to describe things.... Simple.
Now, where's that sarcasm button........dammit!
Why? Because we don't add an extra, unneeded letter (U) to some words. Which also to us would totally change the pronunciation.
Incorrect terms? Oh, here we go about bonnets again!!! And BTW a boot is something worn on the foot.
So then, where is actually the confusion? Maybe it's not us?
Oh yeah, least I forget,,,,Sarcasm off.
