- Describes something (a comment, question, event, idea) that is very unexpected, surprising, random, strange, or seemingly irrelevant to the current context.
Explanation
Origin
Comes from the game of baseball. 'Left field' is one of the outfield positions.
Several theories exist:
- Things happening in or coming from the direction of left field can be unexpected from the perspective of the batter or catcher at home plate.
- Some older baseball stadiums had unusual features near left field (e.g., noisy streets, adjacent mental hospitals like Chicago's West Side Grounds) which led to 'left field' being associated with erratic behavior or unexpected comments (He's out in left field).
- The throw from left field to home plate is long and sometimes unpredictable.
The idiom emerged in American English, likely in the mid-20th century, to mean 'unexpected' or 'strange'.
