Knocking on wood, naturally, is one of the most prevalent superstitions people talk about.

According to Brewer’s Dictionary of Phrase and Fable, “traditionally, certain trees, such as the oak, ash, hazel, hawthorn and willow, had a sacred significance and thus protective powers.”
Furthermore, the theory goes, Christian reformers in Europe may have deliberately transformed this heathenish belief into a more acceptable Christian one by introducing the idea that the “wood” in “knock on wood” referred to the wood of the cross of Jesus’ crucifixion.
However, no tangible evidence supports these origin stories.
The Oxford English Dictionary traces the phrase “touch wood” only back to the early 19th century, locating its origins in a British children’s tag game called Tiggy-touch-wood, in which children could make themselves “exempt…from capture [by] touching wood.”
Of course, much folklore is learned informally, by word of mouth or customary behavior. So it’s possible – even likely – that the phrase and the ritual predate its first appearance in print
