What does this phrase mean: "reak havoc"?

[Nicole]

Hi, I think I have heard or even seen this phrase on CNN:

to reak havoc

From the context it appeared in, I suppose it means to cause havoc but I can't find the word reak in any of my dictionaries. Why is this?
Thank you,
Nicole

Hi Nicole,

I think you'll find it should be wreak meaning cause or inflict.

Hi Alan,

Yes it makes perfect sense. It's good I haven't wreaked any havoc. Thanks a lot .

The reason you are not finding this in a dictionary is that it is misspelled. The correct spelling is: wreak/color], meaning to cause.
