Other forms: representationally
In art, anything that's representational depicts things as they are. A representational portrait of your mom will accurately depict the shape of her face, her hair color, and her eye color.
Representational art depicts recognizable, real-world things, people, or events. A sketch of boats on the ocean, gulls flying overhead in a sky full of clouds, is representational, with every element of the drawing representing something physical. Other types of art are much more abstract, reflecting emotions or ideas — like a Jackson Pollock canvas splattered with paint. Representational comes from the Latin repraesentare, "show or display."
