What does the term "latent fingerprint" mean in Latin?

The term "latent fingerprint" derives from the Latin word "latent," which means "hidden." In the context of forensic science, latent fingerprints are those that are not immediately visible to the naked eye and are typically left behind on surfaces through the natural oils and sweat produced by the skin. These prints require specific techniques, such as powdering or chemical treatments, to be made visible for analysis and identification. This understanding of the word "latent" emphasizes the nature of these fingerprints as not readily seen or obvious, making the choice of "hidden" particularly appropriate.

The other terms would not accurately convey the meaning of "latent" in this context. For example, "visible print" refers to prints that are easily seen, while "recorded print" and "identified" imply that the prints have already been processed or matched, which differs significantly from the initial state of latent fingerprints. Thus, "hidden" captures the essence of what a latent fingerprint is.
