Knocking on wood, also touch wood, is an apotropaic tradition of literally touching, tapping, or knocking on wood, or merely stating that one is doing or intending to do so, in order to avoid "tempting fate" after making a favorable prediction or boast, or a declaration concerning one's own death or another unfavorable situation. In some versions of the tradition, only one person, the speaker, is meant to "knock on wood".[citation needed]


The origin of the custom may be in Celtic or German folklore, wherein supernatural beings are thought to live in trees, and can be invoked for protection. One explanation states that the tradition derived from the Pagans who thought that trees were the homes of fairies, spirits, dryads and many other mystical creatures.[1] In these instances, people might knock on or touch wood to request good luck, or to distract spirits with evil intentions. When in need of a favour or some good luck, one politely mentioned this wish to a tree and then touched the bark, representing the first "knock". The second "knock" was to say "thank you". The knocking was also supposed to prevent evil spirits from hearing your speech and as such stop them from interfering. Alternatively, some traditions have it that by knocking upon wood, you would awaken and release the benevolent wood fairies that dwelt there.[citation needed]

Another explanation links the practice to wooden crucifixes.[1] A more modern theory from a folklore researcher suggests it derives from a form of tag called "Tiggy Touchwood" in which players are safe from being tagged if they are touching wood.[1]

  • In Brazil and Portugal, bater na madeira ("knock on wood") is something actually done physically, three knocks are required after giving an example of a bad thing eventually happening. No verbalization is required, just the three knocks on the closest piece or object of wood. In the absence of wood, someone can say bate na madeira, to prevent the bad thing to happen. People do not actually believe knocking three times on a piece of wood will really protect them, but it is a social habit and it is polite to do so to demonstrate that one doesn't want that bad thing one is talking about to actually happen.[citation needed]
  • In Bulgaria the superstition of "knock on wood" (чукам на дърво chukam na dǎrvo) is reserved for protection against the evil, and is not typically used for attracting good luck.

In most cases the nearest wooden object is used (in some areas, however, tables are exempt); if there are no such objects within immediate reach, a common tongue-in-cheek practice is to knock on one's head. Knocking on wood is often followed by lightly pulling one's earlobe with the same hand. Common phrases to accompany the ritual are "God guard us" (Бог да ни пази Bog da ni pazi) and "may the Devil not hear" (да не чуе Дяволът da ne chue Djavolǎt).
