Etymology

RBI is an initialism from baseball terminology, standing for "Runs Batted In." It originated in the late 19th to early 20th century as baseball statistics became standardized. Unlike morphemes in compound words, each letter represents a standalone word ("Runs," "Batted," "In"), making it a purely abbreviational construct rather than a morphologically segmented term.

  2. A high RBI count often reflects strong offensive performance.

  3. His walk-off hit resulted in two crucial RBI.
