AWKWARD SYNONYMS
obscure; abstruse; recondite
Obscure is the general term for something that is unclear or not easy to understand; abstruse and recondite are more formal terms.
Obscure often expresses dissatisfaction at one's ignorance of or inability to identify something (causation of much mental handicap is obscure | some obscure, niggling, unexplained bitterness), or, more critically, refers to something that's not sufficiently clearly expressed (the legislation is ambiguous or obscure). A reference to an obscure back-bench MP is a dismissive comment, suggesting that this is someone not only little known but deservedly so.
Abstruse means difficult to understand: the most abstruse philosophical inquiry.
Recondite denotes topics that are known and understood by only a few experts: recondite though her theme may be, she demonstrates that it is not without relevance. There is often a critical suggestion that difficulty or obscurity has been deliberately sought out or magnified.
