Etymology
Etymology Information

'nonverifiability' originates from English, specifically the prefix 'non-' and the word 'verifiability', where 'non-' meant 'not' and 'verifiability' comes from 'verify' (from Latin roots) meaning 'to make or show true.'

Historical Evolution

'nonverifiability' changed from the combination of the negative prefix 'non-' + the noun 'verifiability'. 'Verify' comes into English via Old French 'verifier' (from Latin elements 'verus' meaning 'true' and 'facere' meaning 'to make/do'), through Middle English forms such as 'verifien' and modernized to 'verify'; 'verifiability' developed with the suffix '-ability', and 'nonverifiability' is the negative formation of that noun.

Meaning Changes

Initially the roots conveyed 'to make/show true'; over time 'verify' came to mean 'establish truth or accuracy by evidence or proof', and 'nonverifiability' evolved to mean 'not capable of being established as true or confirmed by evidence.'
