Animosity is a strong feeling of dislike or hatred, often lasting for a long time. It can exist between people, groups, or even countries.
From Latin 'animositas' meaning 'spirit' or 'boldness', from 'animus' meaning 'mind' or 'spirit'. Over time, the word shifted from strong feeling in general to specifically hostile feeling.
It’s interesting that a word once about strong spirit turned into one about strong hatred. It’s a reminder that high energy plus a negative direction can harden into long-term grudges between people or groups.
