Which word signifies a feeling of intense dislike?

The term that signifies a feeling of intense dislike is "antipathy." This word derives from the Greek "anti-" meaning "against" and "pathos" meaning "feeling." When someone experiences antipathy, they have a strong aversion or hatred towards something or someone, highlighting a deep-seated hostility.

In contrast, "apathy" denotes a lack of interest or concern, which does not convey dislike but rather indifference. "Sympathy" refers to feelings of compassion or understanding towards someone else's situation, showing empathy rather than distaste. "Affinity," on the other hand, indicates a natural liking or attraction towards someone or something, the opposite of dislike. Thus, "antipathy" is clearly the correct choice, as it captures the essence of intense aversion.
