to take a customary action to ward off misfortune
- (idiomatic, US) Hopefully; a self-directive to undertake the customary action to ward off bad luck.
- I do a lot of walking, and I have never had any knee problems yet, knock on wood.
- Synonym: touch wood (UK, Australia, South Africa, New Zealand)
- The expression is used superstitiously to avert the possibility that something just mentioned (if bad) might not occur, or (if it is a good thing) might occur. The action may or may not be performed, depending on how literally the speaker adheres to the superstition. If it is taken literally, it is usual to attempt physically to touch some wooden object whilst, or shortly after, exclaiming knock on wood. Failure to find and touch a wooden item within a short time may be considered ominous, and cause mental distress to the person involved.
hopefully; used when undertaking such a customary action
