In the context of writing, what is an example of an abstract concept?

An abstract concept refers to ideas or qualities that cannot be perceived through the senses and are not tied to specific physical instances. The phrase "It was a lovely day" exemplifies an abstract concept because "lovely" describes a subjective quality that represents emotions or feelings about the day rather than a physical observation.

Contrastingly, the other choices provide more concrete descriptions. "The sun shone brightly" and "The air felt warm" provide specific sensory details that can be directly observed or experienced. Lastly, "a specific event" implies a distinct occurrence or instance, which also focuses on tangible details. Therefore, the correct choice reflects a broader and more emotional interpretation of an experience, aligning with the definition of an abstract concept.
