- engage in a boxing match (verb)
- any one of several designated areas on a ball field where the batter or catcher or coaches are positioned (noun)

- separate partitioned area in a public place for a few people (noun)
- the quantity contained in a box (noun)
- a predicament from which a skillful or graceful escape is impossible (noun)
- a blow with the hand (usually on the ear) (noun)
- a rectangular drawing (noun)
