IPA: /ˈsɒv.ər.ən.ti/
KK: /ˈsɑvərənti/
The authority of a state to govern itself or another state without interference.
The country fought for its sovereignty after years of colonial rule.
Sovereignty → It is formed from 'sovereign' (from Old French *soverain*, meaning supreme or highest) and the suffix '-ty' (meaning the state or condition of). The word 'sovereignty' refers to the state of being supreme or having ultimate authority.
Think of 'sovereign' meaning supreme, and '-ty' indicating a state or condition — so sovereignty is the state of being supreme.
