Which term describes the simplified form of an object, figure, or landscape in art?

The term that describes the simplified form of an object, figure, or landscape in art is abstraction. Abstraction involves distilling the essence of a subject, reducing it to its fundamental shapes, colors, or forms, often without representing the subject as it appears in the natural world. This approach allows for greater freedom of interpretation and expression, emphasizing emotions, ideas, or concepts over literal representation.

Realism, on the other hand, focuses on depicting subjects as they appear in everyday life, capturing details and textures accurately without simplification. Hyperrealism takes this a step further by creating artworks that resemble high-resolution photographs, often with an intense focus on detail and precision, which contrasts sharply with the notion of abstraction. Conceptualism emphasizes the idea or concept behind the artwork over the final visual representation, which also does not align with the simplified nature of abstraction. Therefore, abstraction is the best fit for the description given, as it emphasizes simplification in art.
