IPA: /ˌpaɪrəˈmeɪniæk/
KK: /ˈpaɪrəˌmeɪnɪæk/
A person who has a strong desire to set fires or is obsessed with fire.
The pyromaniac was arrested after starting several fires in the neighborhood.
Pyromaniac → It is formed from "pyro-" (from Greek "pur" meaning fire) and "maniac" (from Greek "mania" meaning madness or frenzy). The word describes a person who has a compulsion or madness for setting fires.
Imagine someone who has a 'frenzy' ('mania') for 'fire' ('pyro-') — that's why a pyromaniac is someone obsessed with fire.
