IPA: //ˈdʌbəlθɪŋk//
KK: /ˈdʌbəlˌθɪŋk/
A way of thinking where a person accepts two contradictory ideas at the same time, often used to deceive oneself.
In a society where doublethink is common, people may believe that war is peace and freedom is slavery.
Doublethink → It is formed from "double" (from Old English "dūble", meaning twofold or twice) and "think" (from Old English "þencan", meaning to consider or reflect). The word describes the ability to hold two contradictory beliefs simultaneously and accept both as true.
Think of the idea of being 'twofold' ('double') in your thoughts — that's why doublethink means holding two opposing ideas at the same time.
