Etymology: "Prefrontal" is a plain compound: the prefix "pre-", meaning "before" or "in front of," joined to "frontal," which comes from Latin "frons," meaning "forehead" or "front." Put together, the term describes what lies in front of the frontal region of the brain, the part of the forebrain that sits just behind the forehead. The prefix has a long pedigree. It descends from Latin "prae," "before," which English picked up in its own right and also through Middle English "pre-." Medical and anatomical writers have used the "pre-" form freely for centuries to mark something as earlier, anterior, or preceding, which is why it attaches so easily to terms like "frontal" to name a specific region.

Synonyms: anterior, frontal, forebrain, cerebral, higher-order
