means The application of scientific methods and techniques to collect, analyze, and interpret physical evidence for use in criminal and civil investigations and court proceedings.

from From Latin 'forensis,' meaning 'of the forum' — the public square where Roman trials and debates were held. To be 'forensic' originally just meant to be suitable for public argument or courtroom use, not specifically scientific. The word absorbed its modern lab-coat-and-microscope sense only as science itself became the preferred witness, so 'forensic science' literally means 'science fit to be argued before the forum' — the old Roman marketplace of justice now reimagined as a courtroom.
