Which of the following terms is used interchangeably with 'capias'?

The term 'capias' is often used interchangeably with 'warrant of arrest' because both involve legal orders for the apprehension of an individual. A capias specifically directs law enforcement to take a person into custody who is failing to comply with a court order, such as appearing for a scheduled court date. Similarly, a warrant of arrest serves the purpose of authorizing law enforcement to arrest an individual. This close relationship in function and purpose is what allows the two terms to be used interchangeably in legal contexts.

The other terms listed—'undertaking,' 'indictment,' and 'verdict'—have distinct meanings and do not serve the same function as a capias or warrant of arrest. An undertaking typically refers to a promise or commitment, often related to bail conditions. An indictment is a formal charge or accusation of a serious crime, while a verdict is the decision made by a jury or judge at the end of a trial. Each of these terms operates within a different phase of the legal process and for different legal purposes than a capias or arrest warrant.
