Last night CBC had a quiz show on. This version of Test the Nation was called "Watch YOur Language"
IT had spelling questions, word origin questions, language terms, parts of speech, slang, "Made in Canada" and others.
THere was a 70 question quiz which is still available online as of now (not sure how long it will be though). I got 60/70, which should have been 61 since I accidentally clicked on an answer when moving the cursor--darn touch pad.
