The term "run-in" originated in the early 19th century, combining "run" (from Old English rinnan, meaning "to flow or move swiftly") and "in" (from Old English in, meaning "inside"). Initially, it described physical movement into a space (e.g., "a horse running into a field"). Over time, it evolved metaphorically to denote conflicts (e.g., "a run-in with the law") and later specialized in printing to describe continuous text. The dual meanings reflect both literal and figurative "entry" into a situation.
