What Does “Abstruse” Mean?
The word abstruse refers to something that is difficult to understand, obscure, or complex in meaning. It is often used in academic, philosophical, or technical contexts where ideas are not immediately clear.
Tone: Formal / Academic
Intensity: High complexity and low accessibility
An abstruse concept is one that requires effort, deep thinking, or specialized knowledge to understand. It is the opposite of simple communication. Because of its complexity, it can sometimes feel distant or intellectually heavy.
