Usage Note: Traditionally, aberrant is pronounced with stress on the second syllable (ă-bĕr′ənt). A more recent pronunciation, with stress on the first syllable (ăb′ər-ənt), has begun to compete with the older one. In 2009, 57 percent of the Usage Panel preferred the newer pronunciation and 43 percent the older. Nonetheless, both pronunciations should be considered acceptable.
