Etymology: "Perinatal" is a modern medical compound, built from the Greek prefix "peri-" meaning "around" or "about," attached to "natal," which comes from Latin "natalis," meaning "of birth." The Latin "natalis" is itself formed from "natus," the past participle of "nasci," "to be born," and the word reaches English through Middle English "natal," so the sense of "around birth" is literal in its construction. The surprise lies in how little of the word is ancient. Its Greek element "peri-" was a common preposition and prefix in classical times, but nothing in antiquity described the stretch of time that medicine now calls perinatal. The term was assembled in English from these older pieces to name a specific clinical window, so the classical parts supply the meaning while the combination itself is recent.
