n. — Atlantic Canada
any container for berry picking; often a small saucepan or pot.
Type: 3. Semantic Change — OED-3 defines dipper, the object, as 'a utensil for dipping up water' (see OED-3, s.v. "dipper" (5)). In Atlantic Canada, however, dipper may refer to any saucepan or pot-like container, especially one used when berry-picking (DNE, s.v. "dipper"). The semantic generalization of dipper from a pan for dipping up water to any container used to collect berries seems to be special to Newfoundland and PEI. While more common in speech than writing, it has reached the level of a linguistic stereotype. Newfoundland and Labrador Tourism, for instance, exploit this stereotype in a video explaining the term for present-day, spoken Newfoundland English (see NL Tourism "dipper" video).
