The outside part or surface of something, such as a building or object.

**Exterior** → It is formed from "ex-" (meaning out of or from) and "terior" (from Latin *terius*, meaning outer or further). The word "exterior" refers to something that is situated on the outside or outer part.
Think of something that is 'from outside' ('ex-') and 'further out' ('terior') — that's why exterior means the outer part.
