I'm looking for a shorter version of the noun "non-applicability" to complete the following triplet.

Truth is to true as Falsity is to false as X is to na.

What should X be?

Non-applicability has the correct meaning, but I want to find a shorter but equivalent word. For background, I'm writing a programming library and I have subprograms with names corresponding to the names of the above triplet. However, programmers hate long names so I need to find a shorter version of the last subprogram name.

Any suggestions would be appreciated.

  • Perhaps inapplicable? Or just use na, for not applicable. Feb 4, 2014 at 15:07
  • both would be good choices but I'm pretty set on using a noun. Feb 4, 2014 at 15:10

    N/A is a noun when it is used as "null". Feb 4, 2014 at 15:16

Perhaps irrevelance

the quality or state of not relating to or being pertinent to the matter at hand; unimportance

The term is often used dismissively, but that is not intrinsic to the meaning.

  • that's an interesting use of the word. Thank you very much, that finishes the triplet perfectly! Feb 4, 2014 at 15:29
