unascertainable

/ˌʌnæsəˈteɪnəbl̩/ adj

That cannot be ascertained; uncertain, unable to be determined or discovered.

Word Origin Unascertainable is un- 'not' + ascertainable. Ascertain comes from Latin ad- 'to' + certus 'certain,' from cernere 'to separate, sift, decide.' So to ascertain is to make certain by sifting through evidence. Unascertainable means impossible to determine. The root cernere also gives us discern, concern, secret (sifted apart), and certain. It's a word that suggests something beyond our ability to sift out.
