Etymology

The term "first-ever" is a compound adjective formed by combining "first" (Old English fyrst, from Proto-Germanic furistaz, meaning "foremost") and "ever" (Old English ǣfre, meaning "always" or "at any time"). The hyphenated form emphasizes the uniqueness of an event or achievement, highlighting its unprecedented nature. The logic is straightforward: "first" denotes priority, while "ever" extends the scope to all time, creating a sense of historical significance.
