Etymology

pester = pest<annoyance> + er<agent suffix>

  • pest (from Latin pestis, meaning "plague" or "nuisance")
  • er (agent suffix, often indicating someone who performs an action)

Etymology Origin:
The word "pester" originated in the late 16th century, derived from the noun "pest," which referred to a destructive or annoying force (like a plague). Over time, the suffix "-er" was added to form a verb meaning "to act like a pest"—i.e., to annoy persistently. The evolution reflects how language turns nouns into verbs to describe behavior metaphorically.
