Greetings, Jaak!Can you settle the puzzle once and for all?
Did the name "butter" come about because some pronounced "booter" as boo-ter?? I certainly can see how that could happen in German.
BTW, Jaak is a tireless helper. He helped me with some computer problems a couple of years ago that lasted many, many days! I was clueless! He hung in there when others did not.
I guess it's the Flemish in him!!
