IPA: /ˌdɪsɪnfəˈmeɪʃən/
KK: /dɪsˌɪnfərˈmeɪʃən/
False information that is spread intentionally to mislead people, often to influence opinions or hide the truth.
The campaign was filled with disinformation aimed at confusing voters.
Disinformation is formed from "dis-" (meaning apart or away) and "information" (from Latin "informare", meaning to shape or form). The word refers to information that is deliberately shaped or formed to mislead or deceive, hence the idea of separating the truth from falsehood.
Think of 'dis-' meaning apart and 'information' as shaping knowledge — disinformation is knowledge that is shaped to mislead.
