I have to admit I have a really really hard time with this word. A friend told me that reau means one in French but doesn’t help me remember how to spell this word.

Even come up with a useful mnemonic is a bit of a challenge. I would really like to build remember this word. And if I pronounce the word correctly the sound BU are might help me remember the first half. So BU – REAu <REAlly>.

Another way to maybe remember this is each of us wants other people to help us to resolve difficult business issues. So the mnemonic might be:
Business resolved each of us
BU R EA U

Perish the thought I would ever consider memorization.

Summary you are very creative people, if you come up with a witty idea of how to remember this wonderful blankety-blank word I would appreciate your input. Thanks.
