An injunction is an official court order telling someone to do something or to stop doing something. It is used to prevent harm or to protect rights.
It comes from Latin “injungere,” meaning “to join to” or “to impose,” from “in-” (on) and “jungere” (to join). The idea became a command “laid onto” someone by authority.
An injunction is law’s version of a hard stop or a forced action—backed by the power of the court. It can freeze a construction project, stop a book release, or force someone to follow a contract. The word shows how language plus authority can physically change what people are allowed to do.
