Synonym discussion

Sense: adjective/1

All four words describe things that are difficult for most people to understand, but each has a different emphasis. Obscure is the broadest and most common term — it simply means not widely known, without implying specialist knowledge (e.g. an obscure village in the mountains). Arcane often suggests knowledge that is ancient, mysterious, or deliberately hidden (arcane rituals of a secret society). Abstruse focuses on intellectual difficulty: the content is hard to follow even for educated readers (abstruse philosophical arguments). Recondite is the rarest and most formal of the four, describing knowledge that is so deeply specialized that only a tiny handful of experts can access it (recondite details of tax law). Esoteric, unlike the others, carries a neutral-to-positive tone: the small group who understands it is seen as an inner circle with privileged access to something meaningful, not just something unnecessarily hard.

Etymology

GreekLatinEnglish

Derived from Greek esōterikos, meaning 'belonging to an inner circle'. This came from esōterō ('further within'), which is the comparative form of esō ('within'). The term passed into Latin as esotericus and entered English in the 17th century, originally describing the secret teachings that were shared only among a select group of disciples within a philosophical school. The modern meaning has broadened to any subject that requires specialist knowledge to appreciate.
