It will take you to the issue of whether grammar and the meaning of words is simply a matter of convention -if so the differences between the English and American uses of the word "traditional" are not matters of absolute but conventional usage. Accordingly the same song might be traditional in America but no in the UK. Likewise, since ignorance is more common than knowledge, it will always be right to be wrong....

So

A woman's reticule is a "'ambag" (at least in Chatham), one does not fall from or off a bicycle, but "off of" it, and a lavatory is a toilet.

Light blue touch paper and retire.
