KK: /kəʊbɪˈlɪdʒərənt/
A person or nation that helps another in a war, often without being in a formal agreement.
During the conflict, several countries acted as cobelligerents, supporting their allies against a common foe.
Cobelligerent → It is formed from "co-" (meaning together) and "belligerent" (from Latin "belligerare", meaning to wage war). The word describes parties that are waging war together or allied in conflict.
Think of 'together' ('co-') and 'waging war' ('belligerent') to remember that cobelligerent refers to those who are allied in warfare.
