While descriptivists argue that prescriptivism is an unnatural attempt to dictate usage or curtail change, prescriptivists argue that to indiscriminately document "improper" or "inferior" usages sanctions those usages by default and causes language to "deteriorate". Although the debate can become very heated, only a small number of controversial words are usually affected. But the softening of usage notations, from the previous edition, for two words, ain't and irregardless, out of over 450,000 in Webster's Third in 1961, was enough to provoke outrage among many with prescriptivist leanings, who branded the dictionary as "permissive."
