Anything which is incapable of being easily discerned, is confusing, or obscure because it lacks clarity: The inscrutableness of many dictionaries makes it very difficult for users to find out what the word entries actually mean; for example, one dictionary (and others) present:

• The word entry: transpositional, of or pertaining to transposition; involving transposition.
• Then when a person looks up the word transposition, he or she gets the following definitions:

  1. The act of transposing.

  2. The state of being transposed.

  3. Something that has been transposed.

• Another well-known dictionary says, The action of transposing something: transposition of word order; a transposition of an old story into a contemporary context.
• Another example: audacity:

  1. The quality or state of being audacious.

  2. An audacious act, remark, etc.
