What does abstruser mean?
Abstruser is the comparative form of the adjective 'abstruse', meaning more abstruse — that is, harder to understand, particularly because the subject matter is deep, complex, or obscure. It is used to compare two things in terms of their difficulty of comprehension: one lecture, argument, or text can be described as abstruser than another when it demands still greater effort to grasp. The word belongs to formal, often academic registers, appearing in criticism, philosophy, mathematics, and scholarly prose where writers assess the accessibility of ideas. Because English adjectives of three or more syllables typically form the comparative with 'more' rather than with an '-er' suffix, many writers prefer 'more abstruse'; nevertheless, 'abstruser' is an established form and appears in edited prose. Its connotations are neutral to slightly negative, implying not fault in the reader but genuine opacity in the material itself.

Etymology of abstruser
Abstruser derives from 'abstruse', which entered English in the late sixteenth century from Latin 'abstrusus', the past participle of 'abstrudere', meaning 'to conceal, thrust away'. That Latin verb combines 'ab-' ('away') with 'trudere' ('to thrust, push'), the same root seen in 'obtrude', 'intrude', and 'extrude'. The comparative suffix '-er' was added within English following the standard pattern of adjective comparison.
