IPA: /əˈfɜːrməns/
KK: /əˈfɜrməns/
A decision that supports or confirms a previous decision made by a lower court or organization. It can also refer to the act of stating something is true or valid.
The court's affirmance of the lower court's ruling was a significant victory for the plaintiff.
Affirmance is formed from "affirmare" (meaning to make firm or strengthen) and the suffix "-ance" (indicating a state or quality). The word refers to the state of affirming or confirming something.
Think of 'making firm' ('affirmare') to remember that 'affirmance' means the state of confirming or strengthening something.
