Etymology: "Progerias" is the plural of "progeria," a rare genetic condition in which children age far faster than normal. The noun was formed from Ancient Greek "progḗrōs," meaning "prematurely old," with the suffix "-ia," which in medical terms marks a condition or disease. The Greek roots combine "pro-," meaning "before" or "ahead of," with "gêras," meaning "old age," so the name describes aging that arrives ahead of schedule. The plural form is used when discussing more than one case or type of the condition. Because the word is a modern medical coinage built from classical parts, it describes a disorder that the ancient Greeks themselves did not identify. The Greek ingredients were chosen to name a newly recognized pattern, which is why the term sounds classical while describing something the ancient world had no name for.
