'apodeictical' originates from Greek, specifically the word 'apodeiktikos', where 'apo-' meant 'away/from' and 'deiknynai' (from 'deiknumi') meant 'to show'.

Historical Evolution

'apodeictical' passed into Late Latin as 'apodeicticus' (from Greek 'apodeiktikos'), then appeared via Medieval/early Modern Latin and English forms such as 'apodeictic' before becoming the modern English 'apodeictical'.

Initially it meant 'able to be shown' or 'demonstrable'; over time it retained that sense but also came to be used in philosophy to mean 'logically or necessarily true'.
