It's interesting how a word in English can have opposite meanings. "That event is sanctioned by the governing organization." "He was sanctioned for not following proper procedures."
Several years ago, in my days as a technical writer, I had an officemate who was a lesbian Wiccan Pagan who regularly participated in Episcopal worship. (She still is and still does. Not relevant to the current topic, but it informed her personality and my relationship with her. We're still friends.) We had a manager who, in my opinion, was not the best of managers and who would not always react rationally to a given situation.
My officemate was planning on doing something I had my doubts about, and I told her, "You better get sanction for that, or you might be sanctioned."
No wonder many of those who learn English as their second language often find it frustrating!
(P.S. If you're interested in such things, go to Bartleby.com, select the American Hertiage Dictionary, and look up "sanction." A very interesting word history note there.)
