benediction - blessing
The formal word ‘benediction’ originally referred to a Christian prayer invoking divine help or protection for you or somebody you care about. However, it has since been adapted so that it is now also used in a more general sense to mean any expression of good wishes, or to refer to something that promotes goodness or well-being.
