Etymology: A wavebreaker is about as literal as English compounds get: a "wave" and a "breaker," the agent noun from "break." The "breaker" element is the older and more striking one. In English, a breaker was first a wave that breaks, the surf that crashes onto a shore, and later came to name the thing that does the breaking. So the word for the barrier is built from a name for the wave itself, and the sense of "breaker" as the wave came before its use for the structure. The compound describes what the structure does: it stands between open water and the coast, so the swell hits it first and loses its force. Breakwaters, groynes and jetties all share this job, and "wavebreaker" is a more general, plainly descriptive term for the same idea.
