It’s about to get really moist in here. But first, some background is in order. The phenomenon of word aversion—seemingly pedestrian, inoffensive words driving some people up the wall—has garnered increasing attention over the past decade or so. In a recent post on Language Log, University of Pennsylvania linguistics professor Mark Liberman defined the concept as “a feeling of intense, irrational distaste for the sound or sight of a particular word or phrase, not because its use is regarded as etymologically or logically or grammatically wrong, nor because it’s felt to be over-used or redundant or trendy or non-standard, but simply because the word itself somehow feels unpleasant or even disgusting.”[…]
Word aversion is marked by strong reactions triggered by the sound, sight, and sometimes even the thought of certain words, according to Liberman. “Not to the things that they refer to, but to the word itself,” he adds. “The feelings involved seem to be something like disgust.”
Participants on various message boards and online forums have noted serious aversions to, for instance, squab, cornucopia, panties, navel, brainchild, crud, slacks, crevice, and fudge, among numerous others. Ointment, one Language Log reader noted in 2007, “has the same mouth-feel as moist, yet it’s somehow worse.” In response to a 2009 post on the subject by Ben Zimmer, one commenter confided: “The word meal makes me wince. Doubly so when paired with hot.” (Nineteen comments later, someone agreed, declaring: “Meal is a repulsive word.”)
The opposite of this is when a word or phrase is particularly pleasant-sounding, for no particular reason. The classic example of this is “cellar door”, although I’m not sure if it has a name paralleling “word aversion”.
