harass , a 17th-century French borrowing, has traditionally been pronounced [har-uh s] /ˈhær əs/ (Show IPA)
with stress on the first syllable. A newer pronunciation, [huh-ras] /həˈræs/
has developed in North American (but not British) English. While this newer pronunciation is sometimes criticized by older educated speakers, it has become the more common one in the U.S., especially among younger educated speakers, some of whom have only minimal familiarity with the older form.
