I am fairly certain it starts with the letter 'd', but if not, it at least has that letter in it.

Other words that describe it: recondite / cryptic / secret / arcane / "not many people are allowed access."

A friend told me what it was it a ways back. Apparently it was the word-of-the-day on dictionary.com once. (I have not been able to find it there...)

Esconced or niched come to mind, but they're not even credibly obscure. Adytum, perhaps?

  • Thank you! Adytum was the word I was looking for! I would vote you up had I the reputation. Maybe it's not the most obscure word, but at least it's not in Chrome's dictionary... Mar 12, 2014 at 17:04


  • Occult has most of those meanings. Mar 12, 2014 at 5:57
  • The word was adytum, but I really do appreciate this list. I'll remember to use adumbrated some time. Thank you. Mar 12, 2014 at 17:10

Here's a possibility - delitescent?

  • Hello sir, may I enquire... where/how did you find this word? are you a Latin scholar?

  • This is an interesting word that I've not heard of before! I'll have to keep it in mind. @Spehro found the word: adytum. Mar 12, 2014 at 17:07

ar·cane ärˈkān/ adj.
1. understood by few; mysterious or secret.

recondite (rĕk′ən-dīt′, rĭ-kŏn′dīt′) adj.
1. Not easily understood; abstruse. See Synonyms at ambiguous.
2. Concerned with or treating something abstruse or obscure: recondite scholarship.
3. Concealed; hidden.

vocabulary.com on recondite:

It's rather difficult to penetrate the meaning of recondite. Fitting, because it's an adjective that basically means hard for the average mind to understand.

If it's really hard to comprehend, then it's safe to say it's recondite. In the same family as "abstruse," "esoteric" and "totally deep, man," recondite is a very serious word that you could use to describe obscure philosophy books, high level mathematical theory, and the series finale of The Sopranos — you know, things that make your brain hurt.

  • Both those words were given in the question as synonyms of the elusive word. Mar 12, 2014 at 8:28
  • @JanusBahsJacquet Pass the down votes, they can be useful to others. :)
