Which term refers to something that comes from another source or is external?

The term "aliunde" is derived from Latin, meaning "from another place" or "from elsewhere." In legal contexts, it refers to information, evidence, or materials that originate from an external source, rather than being generated from within the primary subject or argument at hand. This can often apply in situations where evidence or testimony is brought forth to support a claim or an argument, coming in from an outside perspective or different context.

This understanding is crucial in various legal frameworks, as it establishes the importance of considering external evidence when evaluating a case or a contractual agreement. External sources can provide additional insights or context that might not be available within the main subject, thereby enriching the overall understanding of the matter.

The other terms serve different functions: "caveat emptor" refers to the principle of "let the buyer beware" in transactions, "ancillary" pertains to something that is supplementary or secondary, and "ante" refers to something that occurred before a certain point in time. These definitions do not relate to the notion of external or sourced origins, which is the key reason why "aliunde" is the appropriate choice in this context.
