If you're a fan of quick dips in the water, you may want to expand your vocabulary beyond "brief swim." Here are some other synonyms to describe your refreshing aquatic activities: 1. Dip: This simple word is perfect for describing a quick, shallow swim. 2. Plunge: If you're feeling brave, you can go for a deeper, more dramatic swim and call it a plunge. 3. Jump: Whether you're hopping off a diving board or leaping into a nearby lake, a jump can be a refreshing way to cool off. 4. Splash: If you're not actually swimming, but just splashing around in the shallow end, this is the perfect word. 5. Paddle: If you're not heading out into a deeper area to swim, but staying close to shore, you can call it a paddle.
