A more thorough explanation:

Definition: A manacle is a type of shackle or handcuff used to restrain someone's hands or feet.

• The police officer put the man in manacles before putting him in the back of the patrol car.
• The prisoner was unable to escape because his hands were bound in manacles.

These examples illustrate how manacles are used to physically restrain someone's movements. They are often used in law enforcement or in situations where someone needs to be kept from escaping or causing harm.
