n.
a public wharf.
Type: 2. Preservation — Government wharf is a wharf built by the government for general use. While previously widespread in many countries, the term has been preserved in New Zealand English and in Canadian English (see Chart 1). In the North American context, Canadian English uses the term in a generic manner, 'any government wharf', whereas in the US the term generally refers to specific places, such as the Government Wharf in Kennebunkport, Maine.
See also COD-2, which uses the label "Cdn".
