scarify (v.)

mid-15c., scarifien, "make incisions in the bark of a tree," from Old French scarifier "score, scrape" (leather or hide), 14c., from Late Latin scarificare, from Latin scarifare "scratch open," from Greek skariphasthai "to scratch an outline, sketch," from skariphos "pencil, stylus," from PIE root *skribh- "to cut, separate, sift." The sense "cover with scars" (1680s) is a sense-shift from influence of scar (v.). Related: Scarified; scarifier; scarifying.
