There’s a lot of hostility out there towards certain words, especially when the complainer sees them as recent innovations, and especially when the words fit certain patterns. For instance, Mark Liberman reported (in “Centuries of disgust and horror”, here) on hostility towards some uses of the suffix –ize, as in incentivize. And direct, or zero, conversion of words to verbs or nouns (which I’ll call verbing and nouning for short) gets a lot of bad press: verbing weirds language (and so does nouning).
The usual objection to zero conversions is that they’re unnecessary: the language already has phrasal equivalents to the innovations, or has existing single-word equivalents. And the usual response to such objections is that the innovations are often shorter than the alternatives (brevity is good) and they almost always express subtleties not conveyed by the alternatives.
But sometimes people object to zero conversions simply on the grounds that they change categories.
Case in point: the nouning of the verb fail.
