Overswim

Part of speech: verb

Definitions

1. To swim over or across a distance, stretch of water, or area, going past its limit

3. Crossing a body of water or passing beyond a point by swimming, often farther than intended

Etymology: "Overswim" is a plain compound: the prefix "over-", meaning beyond a proper limit or too much, joined to "swim", the Old English "swimman," which has been used for moving through water since the earliest English. Put together, the verb means to swim too far, too long, or past a point where one should stop. The "over-" prefix has been productive in English for centuries, which is why speakers could coin a form like this on the spot whenever it was needed. Its sense of excess sits alongside related pairs such as "overeat" and "overwork," where the same logic applies: the action is carried beyond its normal bounds.
