néprouvant
Néprouvant is a rare or proposed French term that would function as an adjective meaning “not proving” or “lacking proof.” It is not listed in major dictionaries and is generally considered a fringe or speculative neologism. The word is formed from the negation prefix ne- combined with prouvant, the present participle of prouver (to prove), but its status as an established term remains unsettled and can be confused with né, the past participle of naître, when written with a space.
In theoretical contexts such as philosophy of language, logic, or rhetoric, néprouvant could be used to describe
Cette hypothèse est néprouvante, car elle n’apporte aucune preuve nouvelle.
Son raisonnement apparaît néprouvant et ne soutient pas la conclusion.
Note: as a coinage outside standard vocabulary, the term may seem unusual to many readers.
probant, preuve, preuve probante, non probant.
There are no widely recognized references for néprouvant; usage remains confined to occasional theoretical or stylistic
