Etymology: Novocaine was coined in 1905 by the German chemist Alfred Einhorn, who was looking for a safer local anesthetic than cocaine. The name blends Latin "novellus", meaning "new", with the "-caine" ending taken from cocaine, the drug it was designed to replace. The result is a name that announces both its purpose and its lineage: a new alternative to the older substance. The word's ingredients are plain, but the way they were combined is the point. "-caine" became a naming pattern, so later local anesthetics such as lidocaine and procaine follow the same ending. Few chemical names have been built so openly on the reputation of a predecessor, and the suffix has since outlived the drug it once echoed.
