Definition of joint

The word "joint" has a fascinating etymology! Initially, it referred to a physical articulation or connection between two bones, as in a joint of the body. This sense of the word dates back to the 14th century, derived from the Old English words "geɣ" (joint) and "jō" (to join). Over time, the meaning of "joint" expanded to include other types of connections, such as a joint of wood (a meeting point where two pieces of wood are fastened) or a joint stock company (a type of business structure where multiple owners invest and share profits). In the 19th century, the word "joint" also took on a new connotation in the slang sense, referring to a pub or tavern where people would gather to socialize and drink – hence, a "joint" is still a common term for a nightclub or bar. Throughout its evolution, the word "joint" has maintained its core meaning of connection or union, reflecting its adaptability and versatility in language.
