IPA: /ˈdɛm.əˌɡɒɡ/
KK: /ˈdɛm.əˌɡɔɡ/
A person, often a political leader, who seeks support by appealing to popular desires and prejudices rather than by using rational argument.
The politician was criticized for being a demagog, as he often stirred up emotions instead of discussing real issues.
Demagog is formed from "demos" (meaning people) and "agōgos" (meaning leader or one who leads). The word describes a leader who seeks to gain popularity by appealing to the emotions and prejudices of the people.
Think of a 'leader' ('agōgos') who speaks to the 'people' ('demos') — that's why a demagog is someone who leads by stirring the emotions of the crowd.
