Etymology

Origin of forensics

First recorded in 1840–45; plural of forensic ( def. ); -ics ( def. )

Explanation

Forensics is the science behind investigating crimes. Studying evidence left at a crime scene is one part of forensics. Forensics can also be called forensic science. Whenever scientific methods — like fingerprint analysis — are applied to a criminal investigation, that's forensics. The word's Latin root is forensis, "in open court," and today much of the evidence uncovered by forensics is eventually presented in open court, as part of a legal case. Another meaning of forensics is "the formal art of debate." If you're interested in speech and debate, you might join your school's forensics team.
