Why “loathsomeness” is a great word

LOATHSOMENESS — [Noun] The quality or state of being extremely repulsive and causing intense disgust. From Middle English lothsomnesse, loþsumnes, from loathsome (from Middle English lothsum, from loth 'loath' + -sum '-some') + the suffix -ness, indicating a state or quality. Unlike "repulsiveness," which suggests a broader, often physical offensiveness that drives away, or "odiousness," which primarily signifies hatefulness of character, loathsomeness focuses on a visceral capacity to provoke profound revulsion. It is the cold, gelatinous touch of something unseen in the dark; the sweet, cloying stench of rot that clings to the back of the throat; the guttural, wet sound of a sickness from the next room. It is disgust made manifest, a quiet horror at the proximity of decay.
