1. Infatuated or smitten: This is the most common meaning. Someone who is "sprung" is deeply and often suddenly attracted to someone else, often in a way that seems obsessive or unrealistic.
Example: "He's totally sprung on her, even though she barely notices him."
2. Caught or arrested: This meaning is less common than the first, and is usually used in the context of law enforcement.
Example: "The thief got sprung after a daring escape."
3. Released: This meaning can be used in a similar way to "caught" or "arrested" but also in other situations where someone is freed from confinement.
Example: "The prisoners were sprung from their cells during the riot."
4. To break free: This meaning is less common but can be used to describe something escaping a constraint.
Example: "The spring on the door sprung and slammed shut."
The meaning of "sprung" will usually be clear from the context of the sentence.
