Use the adjective abstract for something that is not a material object or is general and not based on specific examples.
Abstract is from a Latin word meaning "pulled away, detached," and the basic idea is of something detached from physical, or concrete, reality. It is frequently used of ideas, meaning that they don't have a clear applicability to real life, and of art, meaning that it doesn't pictorially represent reality.
