Have you ever asked: Why do people knock on wood for good luck?

In many cultures, it is usually a superstition that people knock on wood for happiness or refuse an accident. However, while the term “trokitting on wood” known since the 19th century, there seems to be no universal agreement on how it was born.

One of the most common explanations of this phenomenon is the custom of ancient pagan cultures, such as Celts, who believed that ghosts and gods live on trees. Wood knock is believed to have been practiced in order to stimulate good moods and seek protection from supernatural beings.

This can also be a way of expressing appreciation for the happiness that a person has. Another theory is that people knock on wood to avoid evil spirits or to prevent them from listening when they boast of their happiness, thus preventing the change of good fortune into an accident.

Meanwhile, Christians often associate this practice with the tree of the cross from the intersection of Jesus, according to History.com. In the past, pagan people believed that ghosts live in trees, and by knocking people at trees, they could seek the help of the good spirits, or send away evil spirits with that gesture.
