injicio

Injicio is a term used in some scholarly and speculative discussions to denote the act of introducing or inserting an external element into a system, organism, or data stream. It derives from the Latin injicere, meaning "to throw in, to impose." Unlike widely used terms such as injection or insertion, injicio is not a standardized technical term in any major field; it appears primarily as a neo-Latin coinage in cross-disciplinary texts and fictional or theoretical contexts.

In medicine, the basic operation is injection; injicio is sometimes used historically or poetically to refer to the act of delivering a substance into the body, but modern medical terminology prefers injection or inoculation. In materials science or analytics, injicio can be used informally to describe introducing a tracer or reagent into a system for observation.

In computing, the standard concept is injection (for example, SQL injection or code injection). Some proponents have used injicio in speculative writing to emphasize the verb-like nature of injecting data into a program, but it remains nonstandard.

In linguistics and philosophy, injicio may appear in thought experiments about how inputs are embedded into a system or a process, treating "injicio" as a general operation of insertion that transcends domain boundaries.
