second-round

The word "second" originates from the Latin secundus, meaning "following" or "next," derived from the verb sequi (to follow). "Round" entered English via Old French rond, tracing back to Latin rotundus (circular, spherical), which metaphorically extended to mean a completed cycle or stage of activity. Combined as a compound adjective and noun in the 19th century, "second-round" logically denotes the stage immediately following the first, applying the sequential order of "second" to the cyclical concept of a "round" in competitions, elections, or processes. This construction transparently builds its modern meaning from the literal meanings of its components.
