IPA: /mɪsˈprɪʒən/
KK: /mɪsˈprɪʒən/
A failure to report or prevent a crime, especially treason, or a disregard for official duties.
The official was charged with misprision for failing to report the corruption he witnessed.
Misprision is formed from "mis-" (meaning wrong or badly) and "prision" (from Latin "prensio", meaning to seize or take). The word refers to the wrongful or bad understanding or interpretation of something, particularly in a legal context.
Think of 'mis-' meaning wrong and 'prision' relating to taking or seizing — this helps you remember that misprision refers to a wrong understanding or interpretation.
