What word describes a feeling of disgust or revulsion?

The word that describes a feeling of disgust or revulsion is "repulsive." "Repulsive" conveys a strong emotional reaction to something that is deeply offensive or distasteful, capturing the essence of feeling disgusted. This aligns perfectly with the concept of revulsion, as both words signify an aversion to something that is found to be gross or unappealing.

In contrast, "nauseous" refers to a physical sensation often associated with the urge to vomit, which can be related to feelings of disgust but does not exclusively convey the broader emotional concept of revulsion. "Pleasant" and "attractive" are completely opposite in meaning, suggesting enjoyment or appeal rather than disgust. Therefore, "repulsive" is the most accurate choice for describing a feeling of disgust or revulsion.
