A person or device that combs, or a large ocean wave that breaks on shore.
From 'comb' plus the agent suffix '-er.' The 'wave' meaning developed separately from the 'one who combs' meaning, though both use the same root, possibly because the wave's foam resembles combed hair.
A 'comber' wave can reach 30 feet high and is the surfer's dream — the word suggests the wave's rhythmic, comb-like breaking pattern as it approaches the shore in perfect parallel lines.
