The wishbone is a popular tradition every Thanksgiving. This fork-shaped bone can be found in poultry. It is believed that if two people pull the ends of the wishbone, the one who has the bigger piece will have their wishes granted. However, there are various synonyms for this term such as furcula, merrythought, and lucky bone. The furcula is the scientific term for the wishbone in birds which refers to its fork-like appearance. The merrythought is another term for the wishbone, which comes from the merry (or happy) feeling experienced during the breaking of the bone. Lastly, the lucky bone is a common term for the wishbone as it is often associated with good luck and fortune.
