"Knock on wood" is a popular idiom used to express a desire to avoid bad luck or jinx. The spelling of "knock" may seem strange because the "k" is followed by a silent "n". However, this is due to the word's origin in Old English, where the "k" and "n" were both pronounced. Phonetically, "knock on wood" can be transcribed as /nɑk ɒn wʊd/, with the "k" and "n" being pronounced separately. So, if you want to avoid tempting fate, be sure to knock on wood!

Derived from a superstition believed to date back to medieval times, the origin of this phrase is attributed to the practice of touching or knocking on wood to ward off evil spirits or misfortune.
