While "animus" itself isn't commonly used in English, it is the root of many words related to feelings and emotions, such as:
* Animate: To give life to.
* Animal: A living being.
* Magnanimous: Generous and forgiving.
* Unanimous: In complete agreement.
The "osity" suffix in "animosity" signifies a state or quality, making the word mean "a state of hostility or strong dislike."
