IPA: //ˈbaɪfeɪs//
KK: /ˈbaɪfeɪs/
A type of stone tool that has been worked on both sides to create a sharp edge, commonly used in prehistoric times.
The archaeologist discovered a biface while excavating the ancient site.
**Biface** → It is formed from "bi-" (meaning two) and "facere" (meaning to make or do). The word "biface" refers to an object that has been worked on both sides, typically in the context of stone tools.
Think of 'two' ('bi-') sides that have been 'made' ('facere') into a tool — that's why a biface is a tool worked on both sides.
