n. — Newfoundland
a submerged or partially submerged rock over which waves break.
Type: 3. Semantic Change — In Newfoundland, breaker can refer to a rock over which waves break, rather than to the waves themselves, as the OED-3 definition of breaker: 'a heavy ocean-wave which breaks violently into foam against a rocky coast or in passing over reefs or shallows'. Clarke (2010b: 110) notes that because outport communities in Newfoundland had experienced little change from their beginnings in the 18th century up until the mid-20th century, a significant number of fishery-related lexical items has been preserved in the present-day English of the province, including breaker.
