Interior
/ɪnˈtɪriər/noun
The inside part of something; the inner area or inner nature of a place or person.
Did you know?Interior comes from Latin comparatives built on *inter-* (“between, among”), so its oldest sense is about what lies further inside—not a mystical term, but a precise spatial word that later became a favorite in philosophy and psychology.
