Twice in two days we've come across an incorrect use of the verb "coin." Today's misuse appeared in Maureen Dowd's column.
To coin a phrase or word means to invent it.
Sarah Palin did NOT coin the phrase "bass-ackwards." The spoonerism has been around for years. For years! Let's not give Palin any more credit than she deserves. Feel free to interpret that as you will.
