Harmony is to discord as friendship is to what?

The analogy draws a comparison between two opposing concepts. Harmony is associated with a state of agreement, peace, or pleasantness, while discord represents conflict, disagreement, or disharmony. In this context, the second pair of words should reflect a similar relationship where one word embodies a positive connection and the other conveys a contrast or negativity.

Friendship typically represents a positive and supportive relationship between individuals. The corresponding opposite of friendship is enmity, which signifies hostility or opposition between individuals. Therefore, just as discord is fundamentally opposed to harmony, enmity is fundamentally opposed to friendship, making it the most fitting choice in this analogy.

The other choices—support, companionship, and trust—are all aspects or positive attributes of a friendship rather than oppositional concepts. They do not capture the same degree of contrast necessary to complete the analogy effectively.
