enjoin

To enjoin someone often means to formally order them not to do something, most often through a court of law. Think of it as a very strong "don't." It is more than a polite request; it carries legal force. A judge might enjoin a company from polluting a river or enjoin protesters from blocking an entrance. However, you can also enjoin someone to do something, meaning to strongly urge or instruct them to do it. For example: "She enjoined him to take better care of himself." The word sounds formal and a little old-fashioned in everyday speech, but it is still useful when you want to express strong authority or serious advice.

The word "enjoin" carries the weight of formal command and legal authority. Primarily, it means to prohibit or restrain someone from doing something, usually through a court order. This is known as an injunction—a judicial decision that requires a person or group to either do or refrain from doing a specific act. For example: "The judge enjoined the construction company from further damaging the wetlands."

However, "enjoin" also has a less common but important meaning: to strongly urge, direct, or encourage someone to do something. This use is more literary and often suggests a serious request, a duty, or a moral instruction. A sentence such as "He enjoined his troops to fight bravely" gives a sense of leadership and obligation.

Historically, "enjoin" comes from Old French roots meaning "to bind" or "to put under obligation." This origin explains why it implies a strong directive—whether legally binding or morally persuasive. It is often found in legal contexts, formal writing, and historical narratives where authority and command are central themes. While not frequently used in casual conversation, understanding "enjoin" unlocks a nuanced way to describe powerful requests or legal prohibitions.
