Definition of the word incoherence

The word "incoherence" has its roots in 15th-century Latin. The Latin term "incohaerere" means "to stick together badly" or "to be unconnected." This Latin phrase was derived from "in-" (meaning "not" or "opposite of") and "cohaerere" (meaning "to stick together"). In the 1530s, the word "incoherence" was first used in English to describe a state of being disconnected or sundered. Over time, the meaning expanded to encompass a lack of logical connection or unity between ideas, emotions, or actions. Today, "incoherence" is used to describe a lack of sense, consistency, or logic in thought, speech, or behavior. Throughout its history, the word "incoherence" has retained its Latin roots, emphasizing the idea of things falling apart or failing to join together as they should.
