Question

Difference between animosity with and animosity against

Answer 1

First of all, it is Animosity and Enmity not what the question asked. And the meaning of it is ...

Enmity: is a mass noun that speaks of a state of hatred or ill will between two people or groups. This opposition is acted upon and usually mutual. The plural is enmities.

Animosity: means a feeling of hatred or ill will. It is also a mass noun. The plural is animosities.

A related word hostility also means a long-held mutual hatred, but it is usually used to describe the actions taken in response to this feeling. It can also literally mean acts of warfare. The plural is hostilities.

In true fairness, they're both similar to each other.
