Did You Know?
Enjoin has the Latin verb jungere, meaning "to join," at its root, but the kind of joining expressed by enjoin is quite particular: it is about linking someone to an action or activity by either requiring or prohibiting it.
When it's the former at hand—that is, when enjoin is used to mean "to direct or impose by authoritative order or with urgent admonition"—the preposition to is typically employed, as in "they enjoined us to secrecy."
When prohibition is involved, from is common, as in "signs enjoin attendees from photographing the event."
In legal contexts, enjoining involves prohibition by judicial order, through means of an injunction, as in "the judge enjoined them from selling the contract."
