IPA: /ɪnˈdiːsənsi/
KK: /ɪnˈdisənsi/
The quality or state of being inappropriate or offensive, often in a way that is considered morally wrong or shameful.
The comedian was criticized for his indecency during the performance.
Indecency is formed from "in-" (meaning not) and "decens" (from Latin, meaning proper or decent) and the suffix "-y" (indicating a state or condition). The word refers to a state of being not proper or lacking decency.
Think of 'not' ('in-') being combined with 'proper' ('decens') to remember that 'indecency' means a lack of proper behavior.
