What does abstruseness mean?
Abstruseness is a formal noun describing the quality of being difficult to understand. It applies chiefly to written or spoken material — philosophical treatises, legal documents, scientific papers, dense poetry — whose meaning resists ready comprehension. The word derives from the adjective 'abstruse', which entered English from Latin 'abstrusus', meaning 'hidden away'. In use, abstruseness often carries a subtly critical tone: it can suggest that a writer's obscurity is needless or self-indulgent rather than a necessary consequence of complex subject matter. A reviewer might lament the abstruseness of an academic monograph, while a devoted reader might defend it as inseparable from the depth of the ideas involved. Related terms such as 'obscurity', 'opacity', and 'impenetrability' overlap with it, but abstruseness specifically connotes deliberate or inherent remoteness from ordinary understanding. Its antonyms include clarity and lucidity. Though uncommon in everyday speech, it remains a precise and useful term in literary criticism, philosophy, and scholarly discourse generally.

"The abstruseness of the philosopher's prose left most of his students bewildered."
"Critics complained about the abstruseness of the novel's dense, allusive prose."
"Despite its abstruseness, the paper was hailed as a landmark contribution to theoretical physics."
Rarely used in the plural; the word normally functions as an uncountable mass noun denoting a quality.
"The book's various abstrusenesses made it a challenging read from start to finish."
The word 'abstruseness' is itself a bit abstruse — a rare case where a word's meaning and its own difficulty align perfectly.

Etymology of abstruseness
Abstruseness derives from the adjective 'abstruse', which English borrowed in the late sixteenth or early seventeenth century from Latin 'abstrusus', the past participle of 'abstrudere', meaning 'to hide away' or 'to conceal'. That Latin verb combines 'abs-' (away) with 'trudere' (to thrust), so the underlying image is of something thrust out of sight. The noun 'abstruseness' formed regularly from the adjective, sharing its root with words like 'obtrude' and 'intrude', which also descend from 'trudere'.
