Does ‘Uninhibited’ Contain a Double Negative?
The verb inhibit means “to refrain from doing something” or “to hold in check,” as in “climate conditions that inhibit plant growth.” In the fields of psychology and sociology, the participial adjective inhibited often describes those who are unable to express their thoughts and feelings freely:
People with type-D personality tend to have a negative outlook on life and suppress their feelings. They're also likely to be reserved and socially inhibited.

David's left arm is squarely wrapped around his son's narrow frame, his smile classic dad-pride: tight-lipped and composed in the way that fathers smile around sons they don't want to embarrass with sincere displays of emotion, even as their less inhibited children smile, the way Nic does, as if happy laughter isn't far behind.

You might see the in- at the beginning of inhibit and ask yourself: would someone who can express their thoughts and feelings freely therefore be “hibited?” The answer is no—because the in at the beginning of inhibit is not a negative prefix.
Inhibit was borrowed into English in its whole form from the Latin verb inhibēre. The in- part is a Latin prefix, meaning “in” rather than “not,” that combined with the verb habēre (“to have”).
Habēre led to other words in English, including habit and inhabit, but since in- is not a negating prefix, hibited would not be the opposite of inhibited. That honor would go to uninhibited:
There is something exhilarating about seeing an artist have so much uninhibited fun, truly lost in the soundscapes of her own music.
