insubstantiality JUST WRITTEN FOR YOU

/ˌɪnsəbˈstænʃiˈælɪti/ · in·sub·stan·tial·i·ty
noun
  1. The quality or state of being insubstantial; lack of substance, solidity, or material weight. The insubstantiality of the argument became evident when the lawyer could not produce any concrete evidence.
Did you know? Philosophers such as John Locke used the term to discuss the insubstantiality of ideas that lack empirical grounding, and it later appeared in legal jargon to describe evidence that is too flimsy to support a claim.
