What is the primary definition of shackles?

The primary definition of shackles relates to their function of restricting movement. Shackles are typically physical restraints used to secure an individual, often around the wrists or ankles, thereby preventing them from moving freely. This concept is rooted in their historical use for detaining prisoners or individuals deemed a flight risk, where controlling movement is essential for safety and security.

While other options may suggest various actions, such as decorating or expediting, these do not accurately reflect the primary purpose of shackles. The role of shackles as a means to confine individuals and control their movement is pivotal in law enforcement and security contexts, emphasizing their role in ensuring compliance and safety in situations where freedom of movement poses a risk.
