Original meaning: tattoo the face for a crime committed

Pictograph of a person whose face has been tattooed, now written as 墨. In ancient China criminals were punished by having their faces permanently marked. Later writers reanalyzed the character as a chimney being blackened by fire, so the bottom component was written to look like 炎 (flame).
