IPA: /ɪnˈsoʊbrɪəti/
KK: /ɪnˈsoʊbrɪəti/
The state of being unable to think clearly or act normally due to excessive drinking or drug use.
His insobriety led to poor decisions and regretful actions.
Insobriety is formed from "in-" (meaning not) and "sobrius" (from Latin, meaning sober or temperate). The word refers to a state of not being sober, often implying intoxication or lack of moderation.
Think of 'not' ('in-') being combined with 'sober' ('sobrius') to remember that insobriety means a state of not being sober.
