Other forms: proclamations
A proclamation is a formal public statement. If the mayor of your town issued a proclamation honoring the state champion field hockey team, this is an official statement of praise and celebration.
A major statement made in front of an audience or the authoritative word on some subject is a proclamation. It's usually used in an official or government context, although an ordinary person can also make a proclamation, like your proclamation that you'll never dance again after your embarrassment at last week's hip hop recital. The root is proclaim, declare publicly, though the i is dropped in proclamation.
