Which term describes an individual being unlawfully carried away or held against their will?

The term that describes an individual being unlawfully carried away or held against their will is "Kidnapping." This term specifically encompasses the act of taking someone by force, threat, or deceit, with the intent to deprive the individual of their freedom. Kidnapping usually implies that the abductor has the intention of holding the victim for some form of ransom, for further criminal purposes, or for use as leverage against another individual.

While "Abduction" is often used in a similar context, it can refer more broadly to the act of taking someone away without consent, and may not always imply the same level of criminal intent or restraint as kidnapping. The term "Hostage" refers to someone who is held captive to ensure compliance with demands or to gain leverage, and does not necessarily include the act of being taken away. "Capture" is a more general term that can describe taking someone or something by force but does not specifically include the unlawful aspects that characterize kidnapping. Thus, "Kidnapping" is the most accurate term in this context.
