The state of being free and open in behavior or expression, without restraint or social limitations.
Her uninhibitedness allowed her to express her thoughts and feelings freely in front of others.
Uninhibitedness → It is formed from "un-" (meaning not), "inhibited" (from Latin "inhibere", meaning to hold back or restrain), and "-ness" (meaning the state of being). The word describes the state of being not held back or restrained, indicating freedom of expression or behavior.
Think of 'not' ('un-') holding back ('inhibited') — that's why uninhibitedness means the state of being free and expressive.
