...I enjoy hearing the term bralle (spelling ?),or bumberchute for what we call umbrella...

Do you mean Braille? Embossed characters for the blind. Never heard of the second one

I think the obvious confusing one is 'chips' [fries to you] and 'crisps' [chips to you I think], though perhaps jam/jelly
