Knock on wood

18/12/2025

Knocking on wood is traditionally considered a way to ward off envy when hearing good or unbelievable news, particularly if it involves wealth or unexpected success. This simple gesture is thought by many to act as a talisman against bad luck and a way for protection from harm or misfortune. In English-speaking countries, people usually say “Touch wood,” which is more common internationally than the phrase “Knock on wood” used in our countries. Regardless of wording, the underlying purpose remains the same - to protect the person experiencing good fortune and prevent potential misfortune.

However, where did this mysterious superstition originate? One of the most common explanations traces back to ancient pagan beliefs, particularly among the Celtic peoples of Europe. According to legend, certain sacred trees, such as oak and hazel, were considered dwelling places for holy spirits. Knocking on the trunks of these trees may have been a way to awaken the spirits and ask for their protection.

However, there is no concrete evidence directly linking these ancient practices to the modern superstition. Some also associate touching wood with Christian belief, since the cross of Jesus was made of wood. However, folklore experts note that these interpretations are speculative, as they are not mentioned in any medieval writings or sermons.

The most likely explanation is that the first recorded use of the phrase “touch wood” appeared in 1805. Since the 19th century, it has been linked to the English language through a British children’s game called “Tiggy Touchwood.” Touching wood was believed to provide a safe hand and prevent children from being knocked out of the game, which involved chasing one another. From Britain, the practice spread to its colonies and beyond.

The Oxford Dictionary of English Folklore supports this view. The dictionary’s editors found no trace of this custom before the 19th century, and dismissed theories about tree spirits or the Christian cross as romantic inventions. Over time, the superstition, along with the phrases “touch wood” or “knock on wood,” spread almost worldwide. In Turkey, people knock on wood twice or pull on one earlobe to ward off bad luck.

In Italy, the equivalent practice is “touching iron.” Even those who claim not to believe in superstitions often find themselves reaching for the nearest table, door frame, or desk after making or hearing an optimistic comment. The persistence of this custom may reveal more about human psychology than ancient religion. Whether or not we imagine spirits in trees, performing a small action to protect ourselves or our loved ones from misfortune, brings a sense of comfort. Knocking on, touching, or grasping wood provides a charming, albeit slight, illusion of control in a world full of uncertainties.
