IPA: /bɪˈlɛdʒərəns/
KK: /bɪˈlɛdʒərəns/
A tendency to be hostile or aggressive, often associated with a willingness to engage in conflict or war.
The country's belligerence made negotiations difficult and strained international relations.
Belligerence is formed from "bellum" (meaning war) and "-gerent" (from the Latin "gerere", meaning to carry or to bear). The word describes the state of carrying on war or being engaged in conflict.
Think of 'war' ('bellum') being 'carried on' ('gerere') — that's why belligerence means a state of being aggressive or engaged in conflict.
