KK: /ˌɪntəˈrɪəriˌti/
The condition of being focused on one's inner thoughts and feelings rather than external things.
The artist's work reflects a deep sense of interiority, exploring the complexities of human emotions.
Interiority is formed from "interior" (from Latin "interior", meaning inner or within) and the suffix "-ity" (meaning the state or quality of). The word refers to the state or quality of being inner or internal.
Think of 'interior' meaning something 'inner' and '-ity' indicating a state, so interiority refers to the state of being inner.
