n. — Quebec, Alberta, especially Education
a notebook.
Several variants refer to a book of lined paper, often used in school. Boberg's NARVS Survey labelled exercise book as a Newfoundland term, which is not borne out by Chart 2. Boberg also notes that it is a minor variant in Quebec (Boberg 2005: 37), apparently reinforced by the French term "cahier d'exercises" (Boberg 2005: 44). As seen in Chart 1, the term is not more frequent in Canada, but has a regional dimension in Quebec and Alberta, and possibly to a more minor degree in British Columbia (see Chart 2). OED-3 documents the term in British English from 1803, which suggests the term as a preservation from the UK. The more widespread term in Canada is, as in the US, notebook, yet in scribbler and copybook other interesting regional variants exist.
