A person or company that displays their products or art at a fair, trade show, or museum.
From exhibit (Latin exhibere, 'to hold out, present') + -or (Latin agent suffix). The -or ending came directly from Latin and is common in English for professional or role-based nouns.
English actually has two forms—'exhibiter' and 'exhibitor'—but 'exhibitor' is strongly preferred because of its Latin heritage and association with formal settings like museums and trade shows.
