in an abstruse manner; in a way that is difficult to understand or obscure; with dense or complex reasoning.
From abstruse (Latin abstrusus, 'hidden, concealed') + -ly adverb suffix. Abstruse originally meant 'thrust away' or 'hidden from sight.'
Academic papers often begin 'abstrusely' with dense jargon, but ironically, the smartest researchers usually explain things simply—true mastery means you understand something well enough to make it clear, not obscure.
