Which word would be associated with a warm feeling of friendship?

Camaraderie is the term that best captures a warm feeling of friendship. It refers to a spirit of friendly good-fellowship and is often used to describe a bond that exists between people who share experiences or challenges together, thus fostering a sense of closeness and mutual support. This word encompasses the idea of warmth and friendship effectively, making it the most appropriate choice among the given options.

In contrast, the other terms convey negative or distant feelings. Antagonism suggests hostility or opposition between people. Enmity refers to the feeling of being actively opposed or hostile, and isolation denotes a state of being separated from others or being alone, which contradicts the notion of friendship. Thus, camaraderie stands out as the clear choice that aligns with the idea of a warm and friendly relationship.
