A formal or official act of approving; praise, usually given with pleasure or enthusiasm.
Example:
The senate signalled its approbation of the new plan by voting for it unanimously.
Approbation indicates both formal recognition of an accomplishment and happy acceptance of it. An official commendation for bravery is an example of approbation. Getting reelected to office usually indicates public approbation. The social approbation that comes from being a star quarterback in high school makes all the pain worthwhile.
