sormenjäljellä

Sormenjäljellä is a Finnish term that literally means "on the fingerprint" or "with fingerprints." In forensic practice it describes a situation in which a fingerprint, or its traces, is found at a crime scene or on an object, functioning as physical evidence that can link a person to an event. The term is built from sormenjälki (fingerprint) and the adessive suffix -llä/-llä, indicating presence on a surface.

In forensic science, the discovery of fingerprints leads to steps such as documentation, collection, development of latent prints, and comparison with known prints in a database. The quality and completeness of a print determine whether it provides a positive identification or a contextual association. Modern techniques, including powder dusting, chemical development, and digital matching, are used to recover and analyze prints that are visible or latent.

In everyday Finnish, sormenjäljellä can also be used metaphorically to indicate that someone has left a trace or become identifiable through evidence, not only in criminal contexts but also in journalism, storytelling, or investigations. The phrase conveys that actions leave marks that can be traced back to a person, underscoring the persistent nature of evidence in determining accountability.
