Ransom money is typically defined as a sum of money paid in order to secure the release of a captive. However, there are several other synonyms that can be used to describe this concept. One such synonym is "ransom payment," which refers to any type of compensation given to secure the release of someone who is being held captive. Another common synonym is "ransom demand," which describes the demand for payment made by the captors in exchange for the release of their hostage. Other synonyms include "ransom fee," "ransom sum," and "ransom cost." Regardless of the term used, the concept of ransom money remains the same - it is the price paid for freedom.
