They Used the Wrong Word

I gleaned these malapropisms from correspondence or websites. No spell checker will catch these:

"…without further adieu."
"Please review the attached daft proposal."
"We will give you a program you can sue."
"A deep-seeded desire for national sovereignty"
From the Research Channel, which should know better: “Barbara Cochran: Wither broadcast news?”
"Make sure the message of the e-card or e-mail that you are sending is apropos to the environment in which you know the recipient."

Finally, I found my horrifying favorite on a web page that advises people about business writing:

"Further, in the absence of adequate communication, colleagues would find themselves working at Coors purposes and perhaps pursuing opposing goals." http://business.clayton.edu/arjomand/business/writing.html
