harasser noun

harassingly adverb

early 17th century: from French harasser, from harer ‘set a dog on’, from Germanic hare, a cry urging a dog to attack.

Traditionally, the word harass has been pronounced with stress on the first syllable, as “HAR-us.” But the newer pronunciation that puts the stress on the second syllable ("huh-RAS") is increasingly more widespread and is considered standard. This is also true for harassed and harassment.
