Sense: noun/1
Incomprehensibility is the broadest term, describing anything that cannot be understood — from complex academic writing to whispered speech. Unintelligibility focuses specifically on speech or writing that fails to communicate meaning, often because of noise, damage, or poor articulation. Obscurity is milder and suggests something is hard to grasp because it is vague or not well-known, rather than truly impossible to understand. Impenetrability is a vivid metaphor from the idea of a wall you cannot get through; it is used for texts or arguments that resist all attempts at understanding. For example, a foreign language is incomprehensible to a beginner, a faint recording is unintelligible, a poet's private symbolism is obscure, and a badly written academic paper is impenetrable.

Etymology
From Latin 'in-' (not) + 'comprehendere' (to grasp together, understand) + '-ability' (the quality of being able). The word entered English through French in the late 1500s, originally as 'incomprehensibility'. The core idea of 'grasping with the mind' comes from the Latin verb 'comprehendere', which literally means to seize or catch hold of.
