Type: 3. Semantic Change — Spinny may be derived from the verb "to spin", which, when applied to a person in phrases such as "my head was spinning", denotes confusion. A Preservation from British English is ruled out on account of its lack of documentation in OED-3; nor did the term originate in the US, because DARE does not list it. At present, the scenario of an independent Canadian semantic development, hence Type 3 - Semantic Change, seems possible.
See also COD-2, s.v. "spinny", which is marked "Cdn".
- This term is not documented in OED-3, DARE or the Canadian dictionaries ITP Nelson or Gage-5, Gage-3. A frequency chart is not possible because of the term's manifold meanings.
