noun
enmity
EN-muh-tee/ˈenməti/
Deep hostility or ill will.
The neighbors’ hostile stares reveal their enmity.

Etymology
Latin inimicitia named hostility and came from inimicus, literally an “unfriend.” Enmity thus expresses the opposite of amity: an enemy's hostile feeling rather than friendship or goodwill.
In context
