Sense: noun/2
Swash, surge, wash, and backwash all describe water movement on or near a shore, but each focuses on a different part of the process. Swash is the specific uprush of water after a wave breaks — the moment when the wave's energy pushes seawater up the beach. Surge is broader: it can describe any strong forward movement of water, including large waves or tidal movements, and carries a sense of power and volume. Wash is the most general term, covering any instance of water moving over a surface, from a gentle wave on sand to water sloshing across a deck. Backwash is the opposite of swash — the return flow of water as it drains back down the beach into the sea. In practice, a coastal description might say 'the swash carried shells up the sand, and the backwash pulled them back out,' while surge would describe a storm-driven swell that floods a seawall.

Etymology
The word 'swash' first appeared in English in the late 1500s, probably created from the sound that splashing water makes — an onomatopoeic formation similar to 'swish', 'splash', and 'swoosh'. It was originally used for the sound or movement of water. By the early 1600s, the sense had expanded to describe a person who makes a lot of noise and showy movement, like a swordsman striking and clashing — giving rise to the compound 'swashbuckler' (a person who swashes a buckler, or small shield). The typography sense arrived much later, in the 1800s, referring to the flowing, splash-like decorative strokes on letters.
