IPA: /ɪmˈmɒdəsti/
KK: /ɪmˈmɒdəsti/
A situation where someone does not show modesty or behaves in a way that is not humble or reserved.
Her immodesty was evident in the way she boasted about her achievements.
Immodesty is formed from "im-" (meaning not) and "modestus" (from Latin, meaning moderate or restrained). The word describes a lack of moderation or restraint, particularly in behavior or appearance.
Think of 'not' being moderate or restrained — that's why immodesty means a lack of modesty.
