apodeictic
|a-po-deic-tic|
/ˌæpəˈdaɪktɪk/
logically demonstrable
Etymology
'apodeictic' originates from Greek, specifically the word 'apodeiktikos', where 'apo-' meant 'away/from' and 'deiknynai' (root 'deik-') meant 'to show'.
'apodeiktikos' passed into Late Latin/New Latin as 'apodeicticus' and then into English (via scholarly use) as 'apodeictic'.
Initially it meant 'capable of being shown' or 'fit to be demonstrated'; over time it has retained this sense and now means 'logically demonstrable; necessarily true'.
